Using a USB Mixer as an Audio Interface

Mixing console with cables plugged in for recording

At some point in your recording journey, you’ll want to consider an audio interface or a mixer as the core hardware for your digital recording setup. Many mixers now have a USB connection so you can record directly into your computer.

What is the difference between a mixer and a recording interface?

If you’re solely focused on recording, then a dedicated recording interface will generally give you better audio quality, but have less features. All of the audio processing like EQ, compression, and adding effects will be done in the post-production and mixing stage from within your DAW (Digital Audio Workstation).

A dedicated recording interface is generally smaller as it doesn’t have a full strip of controls for each channel like a mixer does. I’ve written a detailed article on the best 2 channel audio interfaces which you should definitely check out.

A mixer by contrast offers many more features for ah… mixing your different audio inputs. These can include EQ, panning, effects (like delay and reverb) and sometimes even gating and compression. A mixer’s primary use is for mixing live performances – but these days there are some excellent mixers available with multi-channel digital outputs that enable you to connect to your DAW for recording also.

Should I get a mixer or an audio interface?

The answer depends on what sort of projects you’ll be working on, the number of instruments you need to record – and to some degree, your available budget. If you’re just recording acoustic guitars and vocals at home, a standard USB recording interface with just a couple of inputs is probably all you need.

If you’re recording a full band you could consider either a multitrack recording interface or a mixer with multitrack digital outputs.

If you plan on performing or recording live then a mixer provides more flexibility. These days there are some great mixers available that also have digital connectivity via USB so they double as a recording interface. In this article we’ll talk about some of the things to consider so you can choose a mixer that suits your needs and look at a few of the good ones available on the market.

Can I use a USB mixer as an audio interface?

Yes you can absolutely use a USB mixer as an audio interface to record directly to your computer. There are now many excellent mixers that have USB connectivity and can record a stereo mix from your mixer, or in some cases record multiple tracks directly into your DAW / recording software.

In this article we’ll review a few of them and provide you with some key things to consider so you can choose one that’s best for you.

Things to consider when choosing a mixer for recording

1. Number of Inputs

The first thing to consider is the number of inputs. Think about how many instruments you could possibly want to use at the same time – then add a couple extra just to be safe! 

If you’re a solo artist for example, you might need a channel for an acoustic guitar, a channel for a vocal microphone and perhaps a stereo channel for a backing track or keyboard. So you could consider a 4 channel mixer. If you can afford it, it’s usually a good idea to go slightly bigger than what you need right now – maybe you’ll do a duo with someone and want to add another microphone input or instrument track.

If you’re planning on recording a full band, the channels you need could look like the following

  1. Kick
  2. Snare Top
  3. Hi hat
  4. Tom 1
  5. Tom 2
  6. Tom 3
  7. Overhead 1
  8. Overhead 2
  9. Bass Guitar
  10. Guitar 1
  11. Guitar 2
  12. Keyboard L
  13. Keyboard R
  14. Vocal 1
  15. Vocal 2

So in this case, a 16 channel mixer would probably be about the right size for your needs.

2. Number of channels for multitrack recording

As well as the actual number of channels that the mixer has, you should also consider how many individual tracks of audio the mixer can record simultaneously. Some mixers only record a stereo mix of the master output from the mixer, while others allow you to record a track for each channel individually. If you’re planning on doing lots of post-production editing and mixing, then you should select a unit that has multiple outputs for multitrack recording, not just a stereo mix.

3. Physical Size

Some mixers are more compact than others. If you’re on the road a lot and want a quick compact setup, then you may want a smaller footprint for easy portability. This may come at the expense of some functionality, so if portability isn’t so important, then a physically bigger mixer will probably have more features.

4. Price

Your available budget is an important consideration. Mixers with digital recording capability start at under $100 for a basic 2 channel USB mixer, to around the $500 for an 8 to 12 channel mixer, around $900 for a good 16 channel mixer and the sky’s the limit at the top end for adding more channels and features!

5. Digital vs Analog

In recent years, digital mixers have become more common. The difference between a digital mixer and an analog mixer is that in a digital mixer, all of the audio is processed using digital circuitry, while in an analog mixer, the audio is processed and routed using analog circuitry. Digital mixers can include many other features like the ability to save presets and settings for a quick recall and certain processing tools that can only be provided via digital like feedback suppression.

8. Other built in features like effects, audio processing

Some mixers also have built in effects like delay and reverb as well as processing tools like equalization, gating and compression. 

7. SD or USB flash recording

The ability to record multiple tracks direct to an SD card or USB stick is useful for recording live performances if you don’t want to carry a dedicated recording computer around to live gigs.

The Selection

We’ve chosen a number of mixers to review that are made by reputable manufactures, they are well-built and offer a good range of features in their range.

Let’s get into the reviews!

Alesis Multimix 4 USB FX Review

Alesis MultiMix 4 USB FX | 4 Channel Compact Studio Mixer with Built In Effects & USB Audio Interface for Home Studio Recording

The Alesis Multimix 4 USB is a compact little 4 channel mixer that is perfect for getting started. You can use it as a stand alone live mixer, or you can record the stereo output from the built-in USB port directly to a computer.

It has two XLR mic preamps so you can run up to two microphones simultaneously. Channel 1 and 2 also provide line level inputs so you can plug in other instruments if you need. Channel 2 has a dedicated high impedance input switch so you can plug a guitar or bass directly in. Channel 3 and 4 are blended together as a stereo channel – perfect for keyboards or backing tracks.

Each channel features a 2 channel EQ (high and low), a pad knob and an FX send. Channel 1 and 2 also have a dedicated gain control knob.

There’s a built in FX processor with 15 built in DSP effects including reverb, delay, chorus and a flanger.

The stereo master outputs are ¼” jack line level and there is also a stereo headphone ¼” jack output.

A standard USB type B socket on the back provides the digital interface for connecting to your computer. The Multimix 4 USB can also connect and record to iPad’s using Apple’s Camera Connection Kit.

Alesis Multimix 4 USB FX Features

  • 4-channel mixer with stereo (2) 1/4″ inputs and 
  • Master Stereo 1/4″ outputs
  • 16-bit, 44.1/48 kHz signal stereo in / stereo out via USB for easy recording and playback
  • (2) XLR inputs with gain trim, switchable high-pass filters, and 48V phantom power

Alesis MultiMix 8 USB FX Review

Alesis MultiMix 8 USB FX – 8 Channel Compact Studio Mixer with Built In Effects & USB Audio Interface for Live Sound and Home Studio Recording

Next on our list is the Alesis MultiMix 8 USB FX which has two extra XLR microphone inputs, an extra stereo line input channel and a stereo auxiliary return. This is still very affordable at only around the $150 mark at the time of writing this review.

The MultiMix 8 also provides a 3 band EQ on channels 1-4 (sweepable mids on channels 1-2). Like the MultiMix 4 USB FX there’s a built in DSP effects module. The MultiMix also provides a dedicated auxiliary send with a stereo aux return if you want to run audio through an external processor or effects unit.

Although the MultiMix 8 offers the USB interface, you can still only record a 2 channel stereo mix, not an individual recording for each channel.

If you need a few more inputs over and above what the Alesis MultiMix 4 provides, this is a great option. In fact, the MultiMix 8 has significantly more options than the Behringer Xenyx Q802USB – and in my opinion offers better value for money.

Alesis MultiMix 8 USB FX Features

  • 4 XLR microphone inputs with dedicated gain control , 48V phantom power and switchable 80hz high pass filter
  • High-impedance input switch on channel 2 for connecting a guitar or bass
  • 8 ¼” jack line level inputs
  • Dedicated auxiliary send and stereo return (or 2 extra channels if you prefer)

  • 3 band EQ on channels 1-4
  • Multicolour LED metering for visual level feedback;

  • Stereo USB recording and playback to and from your computer
  • Plug and Play USB connection with both Mac and PC
  • Compatible with iPad’s via Apple’s USB adapter (sold separately)

Allen & Heath ZEDi-10FX Review

They’ve been around for decades now and they are known for designing and building excellent analog mixing consoles with quiet preamps – used in many professional studios around the world.

In more recent years they have entered the consumer audio space and introduced digital technology to their range – bringing us to the ZEDi-10FX. This attractively designed unit provides a 4 input/4 output 24-bit/96kHz USB audio interface as well as functioning as a very useful standalone analog mixer for live performances.

There are 4 XLR mic inputs, which run through Allen & Heath’s GSPre boutique preamps, providing a very nice sound for the price point of this unit. 2 of these preamp channels also offer high impedance switches for plugging in a guitar or bass. The other 2 offer a pad switch for quietening a hot input if you need to!

All 4 channels provide a dedicated gain knob, lo-cut switch, 3 band EQ, FX send, auxiliary send, Pan and a mix/volume knob. 

There are 2 additional stereo channels, providing a total of 8 analog inputs to this unit. Each channel also provides a headphone cue switch so you can monitor the input of an individual channel or the overall mix through headphones.

There is an impressive range of options for audio routing with this unit. Firstly, you can select which channels you want to send out via USB – options are; channels 1-4, channels 1-2 + the LR mix, channels 1-2 + the Aux and FX sends. There are also multiple options for sending different mixes to the main outputs, monitor outputs and the headphone mix.

The built in DSP FX engine has some very useful reverbs and delays that actually sound good! There’s also a handy tap tempo control and a footswitch for engaging or disengaging the FX.

It’s a bit larger than some of the other mixers with this channel count, but the feature set more than makes up for this. Also, the auto-switching 100V-240V power supply is built into the unit, so one less wall-wart to carry around!

Overall, this is a fantastic unit – with a comprehensive set of features.

The Yamaha MG10XU provides a total of 10 input channels with 4 mic preamps and 3 additional stereo channels. Channels 1-4 provide combination XLR/1/4” jack inputs with dedicated gain controls, 3 band EQ, and 48V phantom power.

On the output side, there are stereo balanced ¼” jack and XLR outputs.
