When it comes to music production, having a solid understanding of the tools at your disposal is crucial to creating a professional-sounding mix. One often overlooked feature in PreSonus’ Studio One is the AUX channel. But what exactly is an AUX channel, and how can it take your mixes to the next level?
What is an AUX Channel?
In Studio One, an AUX channel is a type of auxiliary bus that allows you to process a group of tracks or an entire mix, without affecting the original audio. Think of it as a “helper” channel that enables you to add additional processing power to your mix, without altering the original tracks. AUX channels are essentially virtual buses that can be used to create complex processing chains, route audio, and even create sub-mixes within your main mix.
The Benefits of Using AUX Channels
So, why would you want to use an AUX channel in the first place? There are several benefits to incorporating AUX channels into your workflow:
- Increased processing power: By using an AUX channel, you can add additional processing to your mix, such as compression, EQ, or reverb, without compromising the original audio.
- Improved organization: AUX channels allow you to group tracks together and process them as a single entity, making it easier to manage complex mixes.
- Enhanced creativity: With the ability to create sub-mixes and process groups of tracks, AUX channels open up new possibilities for creative processing and sound design.

Using AUX Channels in Practice
Now that you know how to create an AUX channel, let’s explore some practical applications for using them in your mixes.
Vocal Sub-Mixing
One common use for AUX channels is creating a vocal sub-mix. By grouping all the vocal tracks together and processing them as a single entity, you can create a cohesive and balanced vocal sound.
| AUX Channel Settings | Processing Chain |
|---|---|
| Input: Vocal Tracks 1-5 | Compressor: 3:1 ratio, 10ms attack, 100ms release |
| Send Level: -20dB | EQ: Boost 100Hz by 3dB, Cut 5kHz by 2dB |
| De-esser: 5kHz, -20dB reduction |
Drum Buss Processing
AUX channels can also be used to create a drum buss, allowing you to process the entire drum kit as a single unit.
| AUX Channel Settings | Processing Chain |
|---|---|
| Input: Drum Tracks 1-8 | Compressor: 4:1 ratio, 10ms attack, 100ms release |
| Send Level: -15dB | EQ: Boost 50Hz by 2dB, Cut 200Hz by 3dB |
| Parallel Compression: 10:1 ratio, 10ms attack, 100ms release |
Advanced AUX Channel Techniques
Now that you’re familiar with the basics of AUX channels, let’s explore some advanced techniques to take your mixing skills to the next level.
Using AUX Channels for Creative Processing
AUX channels can be used to create unique, creative processing chains that add character to your mix.
| AUX Channel Settings | Processing Chain |
|---|---|
| Input: Guitar Track | Distortion: Drive 30%, Tone 500Hz |
| Send Level: -10dB | Delay: 100ms, 30% feedback, 50% mix |
| Reverb: Room size 100%, Decay 2s, Dampening 5% |
Using AUX Channels for Automation
AUX channels can also be used to create complex automation curves, allowing you to dynamically process your mix.
Example: Automated Drum Buss Compression
Create an AUX channel with the drum tracks as input, and set up a compression chain with a high ratio and fast attack. Then, automate the threshold to duck the compression during the loudest parts of the song, allowing the drums to breathe.
By now, you should have a solid understanding of what an AUX channel is, how to create one, and some practical applications for using them in your mixes. Remember, AUX channels are like having an extra pair of hands to help you shape and refine your sound. Experiment with different processing chains, and don’t be afraid to push the boundaries of what’s possible!
What are AUX channels in Studio One?
AUX channels, short for Auxiliary channels, are additional channels in Studio One that allow you to process audio signals in various ways before sending them to the main mix. They provide a way to create submixes, add effects, and process individual tracks without affecting the main mix. This flexibility makes AUX channels a powerful tool for shaping your sound and expanding your mix.
By using AUX channels, you can create complex audio routings and processing chains that would be difficult or impossible to achieve with traditional mixing techniques. Additionally, AUX channels can help you to declutter your main mix and focus on the overall balance of your tracks, rather than getting bogged down in individual track processing.
How do I create an AUX channel in Studio One?
To create an AUX channel in Studio One, simply click on the “AUX” button in the Console view and select “New AUX Channel” from the dropdown menu. You can also use the keyboard shortcut “Shift + Ctrl + A” (Windows) or “Shift + Command + A” (Mac) to create a new AUX channel. Once you’ve created the AUX channel, you can start sending audio signals to it from your tracks using the “Send” function.
You can also create an AUX channel by dragging and dropping a track to the AUX channel area in the Console view. This will automatically create a new AUX channel and send the audio signal from the track to the AUX channel. You can then start processing the audio signal on the AUX channel using effects and plugins, and adjust the level and pan to taste.
What’s the difference between a BUS and an AUX channel in Studio One?
A BUS and an AUX channel in Studio One are often confused with each other, but they serve different purposes. A BUS is a type of subgroup that allows you to combine multiple tracks into a single channel, whereas an AUX channel is used to process audio signals in various ways before sending them to the main mix. BUSes are typically used to create submixes of drums, vocals, or other groups of tracks, whereas AUX channels are used to add effects, process individual tracks, or create complex audio routings.
While both BUSes and AUX channels can be used to process audio signals, the key difference lies in how they’re used and routed within the mix. BUSes are typically routed to the main mix, whereas AUX channels can be routed to the main mix, other AUX channels, or even back to individual tracks.
How do I send audio to an AUX channel in Studio One?
To send audio to an AUX channel in Studio One, you’ll need to use the “Send” function. To do this, select the track you want to send audio from, and then click on the “Send” button in the track’s channel strip.

By using multiple AUX channels, you can create a wide range of effects, from simple parallel processing to complex multi-band compression and EQ.
To use multiple AUX channels, simply create a new AUX channel and send the audio signal from the previous AUX channel to the new one. You can then add effects and processing to the new AUX channel, and adjust the levels and panning to taste. By chaining multiple AUX channels together, you can create a wide range of tonal colors and textures that can elevate your mix to the next level.
Can I use AUX channels to create a parallel mix in Studio One?
Yes, you can use AUX channels to create a parallel mix in Studio One. A parallel mix is a technique where you create a duplicate of the main mix, but with different processing and effects. This allows you to create a more contemporary and polished sound, with a separate mix that can be blended with the main mix to create a unique sound.
To create a parallel mix using AUX channels, simply create a new AUX channel and send the entire mix to it using the “Send” function. You can then add different effects and processing to the AUX channel, such as compression, EQ, and reverb, to create a unique sound. Finally, you can blend the parallel mix with the main mix using the fader, to create a larger-than-life sound.
Can I use AUX channels to create a stem mix in Studio One?
Yes, you can use AUX channels to create a stem mix in Studio One. A stem mix is a collection of grouped tracks that are mixed together to create a smaller group of tracks, often used in film and television production. By using AUX channels, you can create stems for drums, vocals, guitars, and other groups of tracks, and then mix them together to create a cohesive and balanced sound.
To create a stem mix using AUX channels, simply create a new AUX channel for each stem, and then send the relevant tracks to each AUX channel using the “Send” function. You can then add effects and processing to each stem, such as compression and EQ, to create a balanced sound. Finally, you can mix the stems together to create a cohesive and professional-sounding mix.
