SOS: Audio Interfaces - Why Does My Audio Software Only See 2 Outputs From My 8-Channel Interface?

Wed, 05 Nov 2025 16:28:22 GMT

It’s tech week. Your show is built. You’ve got cues for the main PA, for the on-stage monitors, for the subs, and for the lobby speakers. You plug in your trusty 8-output USB audio interface, open your cueing software—be it QLab, Show Cue Systems (SCS) , Canvas , Multitracks Playback , or even OBS for video—and... it only sees two outputs. "Speakers (L/R)".

You're losing time, the director is asking to hear the cue again, and you just need it to work.

Don't panic. This is one of the most common and frustrating problems in pro audio, and the fix is almost always the same. Your hardware is not broken. The problem is your drivers and configuration.

This guide will walk you through the fix for both Windows and MacOS .

For MacOS Users (QLab): The Answer is Audio MIDI Setup

On a Mac, the problem is different. MacOS uses "Core Audio," which is inherently multi-channel, so you don't need ASIO. If QLab only sees 2 outputs, it's almost always a configuration issue, not a driver issue.

Your 2-Step Action Plan (MacOS)

Step 1: Configure the Device in "Audio MIDI Setup"

This is the most critical step. You need to tell MacOS that your device is a multi-channel surround sound unit, not just a simple stereo headphone jack.

Plug in your audio interface.
Open "Audio MIDI Setup" (find it in Applications > Utilities).
In the "Audio Devices" window, select your USB audio interface from the list on the left.
Click the "Output" tab.
Find and click the "Configure Speakers..." button at the bottom right.
A new window will pop up. In the "Configuration" dropdown, change it from "Stereo" to "7.1 Surround" (or "Octaphonic," or whatever the highest channel count is).
Click "Apply." You can leave the speaker assignments as they are.

Step 2: Map Your Outputs in QLab

Now that MacOS is exposing all 8 channels, QLab will see them.

Open QLab and go to Settings > Audio.
Select your interface as the device.
Go to the "Device Routing" tab.
You will now see a beautiful grid with all 8 (or more) outputs available. Map QLab's patch outputs (1, 2, 3, 4...) to the corresponding device outputs.

For Windows Users (SCS, Canvas, OBS): The Answer is ASIO

On Windows, this problem is almost always a driver issue.

The Problem: WDM vs. ASIO

When you plug in your interface, Windows tries to be helpful by using its built-in drivers (WDM, DirectSound, WASAPI). These are consumer-grade drivers designed to do one thing: let all your apps (Spotify, YouTube, system alerts) play sound out of one "Default Playback Device," which is almost always a 2-channel stereo pair.

Your professional cueing software (SCS, Canvas, etc.) looks at what Windows is offering, and Windows is only offering "Speakers (L/R)."

The Solution: ASIO

To get all 8, 16, or 32 outputs, you must bypass the Windows system mixer entirely. You need a dedicated "highway" that lets your cueing software talk directly to your audio interface. That highway is called ASIO (Audio Stream Input/Output).

When you use an ASIO driver, your software will no longer see "Speakers (L/R)". It will see the real hardware: "Interface Out 1," "Interface Out 2," "Interface Out 3"... all the way to your final output.

Your 3-Step Action Plan (Windows)

Step 1: Get the Manufacturer's ASIO Driver

This is the most important step. Do not rely on Windows "Plug and Play."

Unplug your USB audio interface.
Go to the manufacturer's website (Focusrite, PreSonus, Roland, Behringer, etc.).
Navigate to the "Support" or "Downloads" section and find your exact interface model.
Download the latest "Driver" or "Software" package for your version of Windows.
Run the installer. This package is what installs the all-important ASIO driver.
Restart your computer, then plug your interface back in.

Step 2: Tell Your Cueing Software to Use ASIO

This is the most common place to get stuck, as every program hides this in a different menu.

For Show Cue Systems (SCS): Go to Options in the main toolbar and select Audio Driver - ASIO (using BASS) . This is the correct setting for multi-channel playback.
For Multitracks Playback / Canvas: Look in Settings > Audio. Ensure the "Audio Device" is set to your interface's ASIO driver, not WDM or DirectSound.
For OBS Studio: OBS's native ASIO support is tricky. You will often need a third-party plugin (like "ASIO for OBS") to add "ASIO Input/Output Capture" sources. In the plugin's properties, you can then select your ASIO driver and see all 8+ channels.

Step 3: Map Your Outputs in the Software

Just selecting the driver gives you access; it doesn't route the sound. Your final step is to tell the software where to send each cue.

In SCS: Go to the Editor > (Click the top "Production" icon) > Production Properties. Under the Devices > Audio Output tab, you will build your logical devices ("Mains," "Monitors," "Lobby") and map them to the "Physical Device" (e.g., "ASIO: Out 1-2," "ASIO: Out 3," "ASIO: Out 4").
In Canvas: Go to Settings > Audio. You'll find an output mapping grid to assign your buses (like "Tracks," "Click," "Guide," "Pad") to your hardware outputs (1, 2, 3, 4...).

Still Stuck? Check the Hardware Itself (All Platforms)

If your software still won't see all the channels, the problem is on the hardware.

Check Your Sample Rate: Some interfaces (like the Roland Octa-Capture) have a "high-quality" mode that reduces the channel count. If your interface is set to 192 kHz, it may be physically limiting itself to 4 outputs [cite: 8908, 8910-8912]. Check the hardware's settings or its software control panel and set the sample rate to 48 kHz or 96 kHz [cite: 8899-8907].
Check Your Interface's Control Panel: Open the interface's own control panel (the software you downloaded in Step 1). It may have an internal "Patch Bay" or "Mixer." Ensure that the audio from your computer (often labeled "WAVE OUT" or "DAW") is routed to your physical outputs [cite: 7999-8001, 8007, 8227-8228].
Check for "Streaming Mode": Many modern interfaces have a switch (physical or in software) that mixes everything down to 2 channels for streaming to Zoom or OBS. Make sure this mode is turned OFF .

That's it. 99% of the time, the path from 2-channel frustration to multi-channel glory is: Install/Check Driver -> Configure Software -> Map Outputs.

Now go run your cues.

Frequently Asked Questions (FAQ)

Bright Ideas for Outdoor Film Screenings and Theatre Off-Seasons: Portable 4K Projectors

Mon, 03 Nov 2025 16:18:39 GMT

The way we watch movies is changing. Audiences are increasingly skipping the traditional big-box cinema, looking for a unique experience without the sticky floors and high-priced junk food. This shift has sparked a boom in pop-up screenings, from outdoor film festivals and municipal "movie in the park" nights to live theatres using their off-seasons to generate new revenue.

No matter the venue or the season, the challenge for all these groups is the same: sourcing projection that is portable, bright enough to compete with ambient light, and delivers the stunning 4K experience audiences now expect.

The 4K "Mirror Trick" Explained

How do these projectors achieve 4K in a small box? Many, including the models we'll see, use an innovative technology called pixel shifting.

They start with a native 2K (or similar) high-speed chip. Tiny mirrors then shift the image imperceptibly between frames, effectively displaying a full 4K UHD resolution on the screen. This "mirror trick" delivers a sharp, 4K-perceived image without the cost, size, and power draw of a massive native 4K chip. It's the key that unlocks portable 4K.

The Budget-Friendly Leader: Barco i600 Series

For organizations starting out or on a tight budget, the i600 series is a compelling choice. It uses this pixel-shifting (which Barco calls SuperShift®) to deliver a premium 4K experience from a compact and affordable projector. It's a clever way to deliver a premium experience while protecting the bottom line.

The Road-Tested Workhorse: Christie HS Series

This is the proven standard in the rental and staging world. The HS series is a robust, road-tested platform. Its main advantage is a significantly larger ecosystem of lens and rigging options . This adaptability is critical for festivals and rental inventories where the setup changes every night, from ultra-short-throw to long-throw applications.

The Next-Gen Powerhouse: Christie Jazz (JS) Series

For those needing maximum brightness, the Jazz (JS) series is the new powerhouse. It's built on a next-gen platform with high-efficiency blue laser technology. This results in a lighter chassis (under 65 lbs) with a massive lumen output , perfect for large screens and competing with the lingering Canadian sunset.

Who Are These For?

Outdoor Film Festivals: Need reliable, bright, 4K-quality projection that can be set up and torn down quickly and adapt to various venues.
Municipalities & Public Venues: Ideal for "movie in the park" nights or adding a new, high-value service for corporate and private venue rentals.
Live Theatres and Performing Arts Centers: A smart off-season investment. Generate new revenue by renting the unit out or hosting your own premium film nights.

The key is versatility. The right investment isn't just a projector; it's a new revenue stream, a tool for community engagement, and a way to bring cinematic magic to new audiences.

At-a-Glance: 4K Projector Comparison

Find the Right Projector for Your Unique Experience

Choosing the right projector involves balancing brightness, portability, picking the right lenses, and all while trying to stay within your budget. At Tech Direction, we specialize in helping organizations find the perfect fit for their needs, from film festivals to live theatres.

How to Stream to Multiple Platforms Simultaneously with OBS

projects@techdirection.com (Projects Team) — Mon, 04 Mar 2024 18:09:47 GMT

Reach your audience across platforms

In the ever-evolving world of live streaming, content creators are constantly looking for ways to maximize their reach. One effective strategy is multi-streaming — broadcasting live to several platforms at once. While OBS Studio, a popular choice among streamers for its powerful and free-to-use broadcasting capabilities, doesn't natively support simultaneous streaming to multiple destinations, there's a seamless workaround: leveraging third-party services. Today, we're diving into how you can extend your live streaming presence across various platforms using OBS Studio in conjunction with services like Restream, Castr, or Streamlabs Prime.

The Power of Third-party Services

Getting Started with Multi-streaming

1. Choose Your Service : Begin by selecting a third-party service that suits your needs. Restream is a popular choice, offering a user-friendly interface and a broad selection of supported platforms. However, Castr and Streamlabs Prime are also excellent options, each with its unique features and pricing plans.

2. Set Up Your Accounts : Once you've chosen your service, the next step is to set up your accounts on the platforms you intend to stream to. Ensure that your profiles are complete and optimized for live content.

3. Configure OBS Studio : With your accounts ready, configure OBS Studio to stream to your chosen third-party service. Navigate to Settings > Stream in OBS, select "Custom..." as the service, and enter the RTMP URL and stream key provided by your multi-streaming service. This links OBS directly to the service, enabling it to redistribute your stream.

4. Start Streaming : With everything set up, you're ready to go live. As you start your broadcast in OBS, your stream will be sent to the third-party service, which then simultaneously broadcasts it to all your selected platforms.

Considerations and Best Practices

While multi-streaming can significantly amplify your online presence, it's essential to be mindful of a few key points. Firstly, check the terms of service for each platform to ensure you're not violating any exclusivity agreements, particularly if you're part of affiliate or partner programs. Secondly, assess your internet connection's upload bandwidth to ensure it can handle the demands of streaming to multiple destinations. Lastly, always conduct test streams to troubleshoot any potential issues before your official broadcast.

Conclusion

Multi-streaming with OBS Studio and third-party services offers a straightforward solution for content creators aiming to maximize their live streaming reach. By following the steps outlined above, you can efficiently broadcast your content across multiple platforms, engaging with a wider audience and maximizing your streaming potential. Remember to choose the right service for your needs, keep an eye on bandwidth requirements, and always test before going live to ensure a smooth streaming experience.

Addressing Audio Issues: Does Removing Ground Plugs Work?

admin@techdirection.com (Dan Nagle) — Thu, 20 Jul 2023 03:41:23 GMT

Dealing With That Pesky Ground Hum

Electrical grounding plays a critical role in the safe operation of any electrical system, including professional audio equipment. Faulty grounding can lead to audio disturbances, electrical shocks, or in worst-case scenarios, electrocution. A common misconception is that removing ground plugs can rectify these issues. Let's dive into the facts and debunk this myth.

In an electrical system, the ground connection provides a safe pathway for electrical energy to dissipate, typically via a physical connection to the Earth. If this connection is not in place, equipment such as microphones, guitars, or amplifiers can become electrically charged, causing a condition known as a "hot chassis". This occurs when normal leakage currents are unable to dissipate, leading to a voltage bias on the equipment.

If a performer, while being in contact with the hot equipment, also touches another object that is grounded, they may experience an electrical shock. The severity of this shock can vary from a mild sensation to a severe jolt, unconsciousness, or even fatality, depending on variables such as the voltage level, the skin's moisture level, and the fault current's impedance.

It's crucial to understand that while electrical safety measures are usually robust on professional stages, occasional oversights can occur. For instance, equipment with a missing or broken ground wire, improperly grounded outlets, and damaged power cords can all contribute to a hot chassis condition.

Moreover, the risk is not limited to the stage alone. Standing in water while handling electrical equipment can also pose a significant hazard. In these cases, the usage of wireless microphones is strongly recommended to minimize risk.

To detect a hot chassis condition and avoid potential accidents, a Non-Contact Voltage Tester (NCVT) can be used. This affordable device can quickly and safely test equipment for voltage biases.

Another essential safety measure is the use of Ground Fault Circuit Interrupter (GFCI) outlets. While not mandatory everywhere, these outlets can prevent severe electrical shocks by detecting and interrupting fault currents.

It's essential to treat any electrical shock as a warning sign of a potential safety ground wire failure. Such incidents necessitate immediate investigation and remediation. Never resort to removing or bypassing ground plugs as a solution to audio disturbances. It's not only ineffective but can also put lives at risk.

In conclusion, ensuring electrical safety in professional audio setups requires proper grounding, routine safety checks, and immediate action in case of irregularities. Prioritizing these aspects can guarantee a safe and sound performance, quite literally!

Limitations of HDMI Signals and A Problem-Solving Guide

Today, we're addressing an intriguing issue one of our readers has been grappling with. They have a long HDMI cable connecting their security camera system to their TV but are running into some puzzling difficulties. Despite working fine when hooked to a computer monitor, the same setup seems incompatible with their TV.

Before diving into a potential solution, let's first understand the basics and the limitations of HDMI cables and signal extensions.

Understanding HDMI Cables and Signal Extension

HDMI (High-Definition Multimedia Interface) cables are commonly used to transmit both audio and video signals between devices. This digital interface offers a superior audiovisual experience without the need for multiple cables, contributing to its popularity in modern home and business setups.

However, HDMI cables come with some limitations:

Cable Length:
The HDMI specification does not define a maximum cable length. However, the longer an HDMI cable is, the more signal degradation occurs, which could eventually lead to loss of picture or sound quality. In practice, the maximum effective length of a standard HDMI cable is often considered to be about 50 feet. Our reader's 100 feet cable is pushing these limits, which may lead to signal degradation or other unexpected issues.
Device Compatibility
HDMI cables should ideally be compatible with all HDMI-enabled devices, but certain technical differences between devices can sometimes cause issues. For example, TV screens and computer monitors handle incoming signals differently, which can occasionally lead to compatibility issues.
Version Differences
HDMI has several versions (e.g., HDMI 1.4, HDMI 2.0, HDMI 2.1, and so forth), each with different capabilities. Not all devices and cables will support all features available in newer versions. Be sure to check the version supported by your cable, as well as the devices you're connecting.

Addressing the Issue at Hand

From the description provided, the problem could be due to one of three factors: cable length, device compatibility, or HDMI version compatibility.

Cable Length
The cable in question is 100 feet long, which is considerably beyond what most HDMI cables can reliably handle. The signal might be reaching the computer monitor but not strong enough for the TV, especially if it's more susceptible to signal degradation.
Device Compatibility
TVs and computer monitors handle HDMI signals differently. Even though they both use HDMI, a signal that works on a monitor might not necessarily work on a TV due to these internal processing differences.
HDMI Version Compatibility
If the TV and the security camera box use different HDMI versions, they might not be fully compatible, especially over a long cable. The computer monitor might have a more compatible HDMI version, allowing it to work with the security camera box.

Potential Solutions

To overcome the above limitations, you may want to consider the following:

HDMI Extenders
HDMI extenders can be used to boost the signal strength over long distances, making them ideal for situations where the cable length exceeds 50 feet.
Signal Converters
If your issue is due to device compatibility, a signal converter could help. These devices can adapt the HDMI signal to a form more easily processed by the receiving device.
HDMI Version Adapters
If the issue is due to HDMI version differences, an HDMI version adapter can help bridge the gap, allowing devices with different HDMI versions to communicate more effectively.

In conclusion, while HDMI cables are a convenient way to connect audiovisual devices, they come with their own set of limitations and potential compatibility issues. As technology advances, we hope to see these issues become less prominent, but for now, understanding these limitations can help troubleshoot and prevent potential problems.

If you're still facing issues, it might be worthwhile to seek professional advice. In many cases, the root of the problem can be tricky to identify, and professional technicians would be equipped with the necessary tools and expertise to diagnose and solve the issue. Happy troubleshooting!

Taming Rogue Frequencies: A Guide to Multiband Compressors for Live Productions

admin@techdirection.com (Dan Nagle) — Thu, 06 Jul 2023 16:30:00 GMT

A Guide to Multiband Compressors

Let's explore one of professional audio engineers' secret weapons: the Multiband Compressor. This is a powerful tool in the audio engineer's arsenal, especially in live productions. But what exactly are they, and how are they used? Let's break it down.

What is a Multiband Compressor?

A multiband compressor is an audio processing tool that allows engineers to compress different frequency bands independently. This means that instead of applying the same compression to the entire frequency spectrum of a sound, different settings can be applied to the lows, mids, and highs. This granularity can be critical in shaping and balancing the sound in a live context.

Common Uses in Live Productions

1. Vocal Clarity and Smoothness

One of the most common uses for multiband compressors in live settings is to manage vocals. They can help keep the vocals clear and smooth, reducing the harshness from excessive sibilance (those 's' and 'sh' sounds) or plosives (the 'p' and 'b' sounds). By only compressing the frequency ranges where these sounds typically reside, the overall vocal performance remains dynamic and natural, while the problematic frequencies are controlled.

2. Instrument Balancing

Multiband compressors can also be used to balance the sound of different instruments. For example, in a live band performance, the low-end frequencies from the bass guitar might conflict with the kick drum. With a multiband compressor, you can compress only the conflicting frequencies, allowing both instruments to coexist harmoniously in the mix.

3. Taming Feedback

Feedback is a common issue in live sound situations, especially with open microphones on stage. Multiband compressors can be used as a preventative measure, compressing the specific frequencies where feedback is likely to occur without affecting the rest of the audio.

4. Mastering the Mix

Finally, multiband compressors are often used on the master bus to glue the mix together. By subtly compressing each frequency band as needed, they can help to achieve a balanced and cohesive sound across the whole mix.

The Art of Compression

While the technical aspects of multiband compression are important, it's also an art form. It's about listening and making adjustments to serve the music. The goal is to enhance the live experience, capturing the spirit of the performance while ensuring that every note, every beat, every voice comes through with clarity and impact.

Glossary of Key Terms

- Frequency Bands: Ranges of frequencies in the audio spectrum. Common bands include lows (bass), mids (midrange), and highs (treble).

- Threshold: The level at which the compressor starts to work. If the signal level exceeds the threshold, it will be compressed.

- Ratio: The amount of compression that is applied to signals that exceed the threshold. A ratio of 4:1 means that for every 4 dB the input level exceeds the threshold, the output will only increase by 1 dB.

- Attack: The speed at which the compressor starts to work after the signal exceeds the threshold.

- Release: The speed at which the compressor stops working after the signal falls below the threshold.

- Output Gain (or Makeup Gain): An adjustment to the output level of the compressor to compensate for the reduction in level caused by compression.

- Bypass: A function that allows you to turn off the compressor (or individual bands) temporarily, so you can compare the processed and unprocessed sound.

- Compressor: An audio processing tool that reduces the dynamic range of a signal, making the loud parts quieter.

- Multiband Compressor: A type of compressor that allows different frequency bands to be compressed independently.

Steps to Set Up a Multiband Compressor

1. Identify the Frequency Bands:

Start by splitting your signal into different frequency bands. Most multiband compressors come with presets that divide the frequency spectrum into lows, mids, and highs. You may need to adjust these based on the specific needs of your mix.

2. Set the Threshold:

For each frequency band, set the threshold at which compression will start to be applied. Any signal that exceeds this level will be compressed.

3. Adjust the Ratio:

This determines how much compression is applied once the signal exceeds the threshold. A higher ratio results in more compression.

4. Set the Attack and Release:

The attack controls how quickly the compressor responds once the threshold is exceeded, and the release determines how quickly the compressor stops compressing after the signal drops below the threshold.

5. Fine-Tune the Output Gain:

After compression, you may need to adjust the output gain of each band to balance the overall sound.

6. Bypass Bands and Compare:

To evaluate the effect of your compression, bypass individual bands or the whole compressor and compare the processed and unprocessed sound.

Remember, these are just basic guidelines. The specific settings will depend on your mix and what you're trying to achieve.

Understanding EQ and How to Use It: Your Guide to Mastering Frequency Charts and Professional Audio Mixing

admin@techdirection.com (Dan Nagle) — Wed, 14 Jun 2023 14:44:36 GMT

How to Use PEQ (Parametric Equalizer)

When it comes to professional audio, a deep understanding of EQ (Equalization) is crucial. The ability to manipulate the balance of different frequencies in an audio signal allows you to craft a mix that is both clear and balanced. In this blog post, we'll delve into the intricacies of frequency charts, explore the frequency ranges of different instruments and human vocals, and share tips on how to use EQ on an audio console to tailor the Parametric EQ (PEQ) on each input channel to its sound source.

Frequency Charts and How They Work

A frequency chart, also known as an audio frequency spectrum chart, is a graphical representation of the audible frequency range that human beings can hear, typically from 20 Hz to 20,000 Hz (20 kHz). The chart is split into three main regions: the lows (bass), mids, and highs (treble).

Low frequencies (20 Hz - 250 Hz) are where the bass resides, including the low-end thump of a kick drum or the deep resonance of a bass guitar. Mid frequencies (250 Hz - 4 kHz) are where most of the characteristics of musical instruments are found. High frequencies (4 kHz - 20 kHz) contain the sparkle and clarity of the sound, including the brightness of cymbals and the sibilance in vocal sounds.

Frequency Ranges of Different Instruments and Vocals

Understanding the frequency range of different instruments and vocals can help you make better EQ decisions. Here's a quick guide to the "core" frequencies created by common instruments and vocals, keeping in mind there are exceptions outside of this and most sources will create harmonics that might land outside of these ranges:

1. Kick Drum: 60 - 250 Hz

2. Snare Drum: 120 - 300 Hz (body), 2 - 4 kHz (snap)

3. Bass Guitar: 60 - 250 Hz (body), 700 - 1.5 kHz (pick)

4. Electric Guitar: 80 - 1.2 kHz (body), 700 - 1.5 kHz (pick)

5. Acoustic Guitar: 80 - 1.2 kHz (body), 700 - 1.5 kHz (pick)

6. Piano: 80 - 4.2 kHz

7. Violin: 200 - 2.8 kHz

8. Male Vocals: 100 - 1 kHz (fundamental frequencies)

9. Female Vocals: 250 - 1.5 kHz (fundamental frequencies)

NOTE: For vocals, these ranges are also very important:

2 - 4 kHz (presence/recognition)
4 kHz - 9kHz (sibiliance, "ess" and "tee" sounds")
10 kHz - 16 kHz (breath or "air" sounds, often referred to as "brightness" or "airyness"

Remember, these are just approximate values, as the frequency range can vary depending on the specific instrument or voice.

Using EQ on an Audio Console

Let's now move on to the practical application of EQ on an audio console. Here are some tips on how to use EQ to tailor the PEQ on each input channel to its sound source:

1. Identify the Frequency Range: The first step is to identify the frequency range of the sound source. Use your ears and refer to the frequency ranges above to figure out where the instrument or voice sits in the mix.

2. Cut Before You Boost: It's generally a good idea to cut (reduce) frequencies before boosting them. This is because boosting can often bring unnecessary noise up too or cause feedback or a harsh sound.

3. Use High-Pass and Low-Pass Filters: High-pass filters cut off all frequencies below a certain point, while low-pass filters cut off all frequencies above a certain point. Use these to remove unnecessary low or high frequencies from the sound source only when you are certain the sound source won't contain it.

4. Sweep and Destroy: If you can't quite figure out what frequency is causing issues, boost a narrow band of frequencies and "sweep" the PEQ frequency adjustment across the spectrum until you find the frequency that is causing the problem. Once you've found it, reduce (cut) that frequency.

5. Be Subtle: Subtle changes often work best when it comes to EQ. Extreme cuts or boosts can make the sound unnatural or unbalanced.

6. Use Your Ears: Ultimately, your ears are the best judge. Trust your instincts and make adjustments based on what sounds good in the mix.

Conclusion

Mastering EQ is a key aspect of professional audio mixing. By understanding how frequency charts work and the characteristic frequency ranges of different sound sources, you can use EQ effectively to create a clear, balanced mix. It may take a bit of practice, but with time and experience training your ears, you'll find that EQ is an incredibly powerful tool in your audio engineering toolkit.

To set up a matrix on an audio console using the most common use case, follow these general steps (specific console operations may vary):

Step-by-Step Guide To Setting Up A Matrix

1. Access the matrix routing section on the audio console, typically found in the routing or output section.

2. Determine the number of inputs and outputs you require for your matrix. For example, if you want to create a matrix to distribute audio to delay speakers, you may have multiple inputs (e.g., main mix, vocal group, instrument group) and multiple outputs (e.g., delay speakers 1, delay speakers 2).

3. Assign your desired input signals to the matrix inputs. This can usually be done by selecting the source channel or bus and routing it to a specific matrix input.

4. Assign your desired output destinations to the matrix outputs. For instance, route the matrix outputs to the appropriate delay speakers, foldback systems, or other desired destinations.

5. Adjust the levels or routes for each matrix crosspoint. Set the appropriate levels or panning positions for each combination of input and output, ensuring the desired audio mix and distribution.

6. Test the matrix setup by playing audio and monitoring the output at each destination to ensure proper routing and balance.

7. Save the matrix configuration as a preset or scene if the console supports it, allowing for quick recall in future performances

8. Fine-tune the matrix settings as needed. During rehearsals or performances, you may discover the need to adjust individual input levels, output levels, or routing configurations within the matrix. Make these adjustments to achieve the desired audio balance and distribution.

9. Label and document your matrix setup. It's essential to label each matrix input and output to maintain clarity and facilitate future troubleshooting. Additionally, document your matrix settings, including the assigned inputs, outputs, and levels, for reference in subsequent shows or if you need to recreate the setup.

10. Test the matrix setup thoroughly before the live performance. Run through different audio scenarios, such as various input combinations and output destinations, to ensure the matrix functions as intended and that all audio signals are properly routed and balanced.

Remember, these steps provide a general guideline for setting up a matrix on an audio console. The specific procedures may vary depending on the console manufacturer and model.

Using QLab to Fire Your Lighting Console Cues

admin@techdirection.com (Dan Nagle) — Mon, 27 Feb 2023 20:26:01 GMT

Step-by-Step Guide to Setting up OSC Control Between QLab and Your ETC Eos Console or Software (ETCnomad)

Theatrical productions often require the seamless integration of numerous technical elements. Two crucial components of this process are QLab, a very popular control software, and ETC Eos consoles, industry-leading lighting control consoles. In this post, we will discuss how to connect these two systems using Open Sound Control (OSC), allowing you to trigger specific scenes with Network cues in QLab which, in turn, command the Eos console to "Go" on a specific scene.

Preparations

Before we start, make sure you have:

1. A Mac running QLab (make sure you have the latest version installed).

2. An ETC Eos console with the latest software update.

3. Both devices connected to the same network.

4. A basic understanding of OSC (Open Sound Control), a protocol used for networking sound synthesizers, computers, and other multimedia devices for purposes such as musical performance or show control.

Setting Up ETC Eos Console

First, you'll need to enable OSC in your Eos console and set up your cues.

1. Open the Eos software on your console.

2. Navigate to the shell settings (Settings > Show Settings > OSC).

3. Enable OSC and note the port numbers for OSC transmit and receive. Typically, the default port is 3032 for transmit and 3033 for receive.

4. Create your lighting scenes within the Eos software, each with a unique cue number.

Setting Up QLab

With your Eos console ready, let's move on to QLab.

1. Open QLab on your Mac.

2. Create a new workspace or open an existing one.

3. For each lighting scene you want to trigger in the Eos console, create a new Network cue in QLab.

4. In the settings for each Network cue, select 'OSC Message' as the type.

5. Set the destination IP to the IP of your Eos console and the destination port to the OSC receive port you noted from the Eos settings.

6. In the message field, enter the OSC command for recalling a cue in the Eos software. The syntax typically is `/cue/{cue number}/go`, where `{cue number}` is replaced with the number of the cue you want to trigger.

Triggering Scenes

With everything set up, triggering your lighting scenes from QLab is now as simple as firing the corresponding Network cue. The OSC message will be sent to the Eos console, which will interpret the command and execute the desired cue.

Conclusion

By integrating QLab with ETC Eos consoles using OSC, you can streamline your production workflow, automating complex audio, video, and lighting cues with a single command. This efficient and powerful setup allows you to focus more on the artistic aspects of your production and less on the technical details.

How To Use a Compressor in Live Sound

admin@techdirection.com (Dan Nagle) — Wed, 18 Jan 2023 20:31:25 GMT

Compressors In Live Sound - A Step-by-Step Guide

One crucial tool in your audio engineer toolkit is the compressor. This little device can be a game changer when it comes to managing the dynamics of your mix. But what exactly is a compressor, and how do you use it? Let's dive in!

What is a Compressor?

In the simplest terms, a compressor is a device that controls the dynamic range of an audio signal. The dynamic range is the difference between the loudest and softest parts of a sound. By using a compressor, you can ensure that your quiet parts aren't too soft, and your loud parts aren't too loud, leading to a balanced and pleasant listening experience.

Controls on a Compressor

Understanding the controls on a compressor is key to using it effectively. Here are the basic controls you will find on most compressors:

1. Threshold: This is the level at which the compressor starts to work. If the signal level goes above the threshold, the compressor kicks in.

2. Ratio: This control determines how much compression is applied once the signal goes above the threshold. For example, a ratio of 4:1 means that for every 4dB above the threshold, the output will only increase by 1dB.

3. Attack: This is how quickly the compressor starts working after the signal exceeds the threshold.

4. Release: This control sets how long it takes for the compressor to stop compressing after the signal drops below the threshold.

5. Make-up Gain or Output: After compression, the level of the signal is often lower than the original. The make-up gain allows you to boost the compressed signal back up to a desired level.

How to Use a Compressor in Live Sound

Now that you're familiar with the controls, let's discuss how to use a compressor in a live sound context.

1. Set the Threshold: Start with your threshold at 0dB (or the maximum value), and then lower it until the compressor starts to react to the loudest parts of the input signal.

2. Choose a Ratio: A good starting point might be a ratio of 3:1 or 4:1. This is enough to tame the dynamics without squashing them too much.

3. Adjust the Attack and Release: For vocals, a fast attack and a medium release might be a good starting point. For drums, you might want a slower attack to let the initial 'hit' come through and a faster release.

4. Set the Make-Up Gain: After setting the other controls, adjust the make-up gain so that the output level matches the input level when the compressor is bypassed.

Remember, every voice and instrument is different, so there's no one-size-fits-all setting for compressors. The best way to learn is by experimenting and using your ears.

The Magic of Compression

The magic of compression lies in its ability to smooth out the dynamics of a performance. This can help to prevent feedback, reduce vocal strain, and bring out subtle details in the music. When used correctly, compression can help to create a more polished and professional sound in your live mixes. So, don't be afraid to dive in and start experimenting with this powerful audio tool! Just maybe try it first in rehearsal, practise, or with a music track with no live performance happening and a good pair of headphones.

Happy mixing!
