When setting up a home studio, getting ready for a live show, or making a podcast, it’s helpful to know how to connect your audio mixer to other gear. The mixer is the main part of your setup. You can improve your sound once you know how to connect different things. In this article, we’ll go over the most popular ways of mixer connectivity, such as XLR, USB, Bluetooth, and more, so you can get the most out of your gear.
Why XLR is Essential for Professional Audio Setups
What is it?
XLR doesn’t officially stand for “External Line Return.” It’s commonly referred to by the initials of its original manufacturer (Cannon X series, Latch, Rubber), but it’s now just known as “XLR.”
Why it’s great:
- When music is balanced, noise is cut down over long wire runs.
- A locking device stops the link from being lost by accident.
- Gives 48V of phantom power to condenser mics.
When to use it:
For mics, use XLR hookups, especially when recording in the studio or live. It guarantees the best sound clarity and reliability.
RS vs. TS: The 1/4-Inch Connectors You Need to Know
What is it?
They come in two different kinds:
- For uneven mono sounds, like those from electric guitars, use TS (Tip-Sleeve).
- TRS stands for “Tip, Ring, Sleeve.” It is used for balanced mono or unbalanced stereo signals, like those from headphones or an audio interface.
Why it’s great:
- It works with a lot of different singing instruments.
- This unit is simple to use and connect to interfaces, mixers, and amps.
TRS cables work best with line-level sources like keyboards and outboard gear, while TS cables are more popular with guitars and other solo instruments.
RCA: Old School But Still Useful
What is it?
Radio Corporation of America (RCA) plugs are color-coded jacks that are popular in home audio and video equipment. They are usually red and white.
Why it’s great:
- Simple and not too expensive.
- It’s on DJ controls, home stereos, and other older gear.
When to use it:
It’s best to use it to connect mixers to CD players, turntables (with an amplifier), or other low-end audio sources.
Digital Audio Made Simple: USB Mixer Connections
What is it?
Your mixer can connect directly to a computer or mobile device via USB, letting you play and record digital audio.
Why it’s great:
- Allows recording and playing back on multiple tracks.
- It’s great for making songs, livestreaming, and podcasts.
- Digital Audio Workstations (DAWs) often let you just plug them in and play.
When to use it:
If you’re recording on a DAW, podcasting, or livestreaming, a USB mixer is a must. It simplifies digital routing and makes recording setups far more efficient.
Bluetooth: The Ease of Wireless
What is it?
Mixers that have Bluetooth let you play music from phones, tablets, or computers without wires.
Why it’s great:
- No need for wires.
- Easy to play for fun, listening or during breaks in live sets.
When to use it:
Bluetooth is great for quick playing of music, background tracks, or simple wifi links. Keep in mind that Bluetooth might have delay problems, so it’s not the best for real-time use.
Ethernet or Network (AVB, Dante, etc.): For More Complex Setups
What is it?
Network methods like Dante, AVB, or AES67 are used by some mixers, especially digital or live sound mixers, to send stereo audio over Ethernet.
Why it’s great:
- It can handle many radio sources at once with little delay.
- The sound is great for big events and television sets.
- Allows for long wire runs without any problems.
When to use it:
If you’re managing a large-scale production or planning to expand your system in the future, networked mixers can scale easily. Learn about upcoming mixer technology trends for 2025 to see how Ethernet and digital protocols are becoming the new standard.
How to Use Aux Sends and Returns for Custom Sound Control
What is it?
With aux sends and returns, you can send sound to outside devices, like effects processors or stage speakers, without mixing it with the main sound.
Why it’s great:
- Allows artists to make their own monitor mixes.
- Allows control of outside events in real time.
When to use it:
Aux sends are necessary for live sound when artists need their own monitor mixes or when you want to add effects like reverb, delay, or other noise to certain channels.
High-Fidelity Expansion for Digital I/O (S/PDIF, ADAT, etc.)
What is it?
Sony/Philips Digital Interface (S/PDIF) and Alesis Digital Audio Tape (ADAT) are two examples of digital audio interfaces that let you move digital audio from one piece of equipment to another.
Why it’s great:
- Keeps the quality of the music without any extra changes.
- Allows connecting additional gear or increasing the number of inputs and outputs.
When to use it:
These are great for adding to studio sets or connecting digital processors so that the sound stays clear and the delay is low.
Conclusion
When picking a mixer, it’s important to consider a few key factors. Start with the gear you already have—such as microphones, instruments, and your computer setup. Then, think about how you plan to use the mixer: is it for live performances, recording sessions, or streaming? Also, consider your future needs, like extra channels or built-in effects. Modern mixers often combine multiple features, so understanding the different types of connections, like XLR, USB, or Bluetooth, will help you get the best performance and avoid surprises. Mastering your mixer’s inputs and outputs is essential for achieving professional-level sound.
