Lexicon has long been famed for its legendary industry standard reverb units found in most professional studio.

But Lexicon don’t just do reverb, they also make high performance audio interfaces to sit at the heart of your desktop project studio.

We recently looked at the Lexicon Omega for it’s ability to operate with iPad.  But this post takes a look at the I.O range of devices.

Lexicon USB Audio Interface

The I.O range (previously know as the IONIX ‘U’ series, see video below) is designed to fit comfortably in front of your computer and offer convenient control of your audio sources, with dedicated level controls for each input channel, together with a chunky master output volume control, headphone volume and control for fading between monitor and direct signal.

Each device in the range offers a set of high quality mic preamps (by DBx), line and Hi-Z inputs that deliver pristine 24-bit/96kHz audio via a convenient USB connection.

Each also comes with a suite of software so you can get started straight out of the box (Steinberg Cubase LE multi-track, Lexicon Pantheon Reverb VST/AU Plugin, Toon Track EZ drummer lite and the XILS3 SE modular synth.  But each will complement any DAW and plugins you want to work with.  Each device in the range is also fully compatible with Pro Tools.

The built in MIDI I/O is also a great asset.  If your MIDI set up is small you may not need a separate MIDI interface at all, just plug in your master controller keyboard.

This feature comparison chart for the range can be found on the Lexicon site.

You can find a Sound On Sound magazine review of the I.O 82 here, there’s also a mention of the I.O 22 and 42.

Here are the 3 flavours of the Lexicon I.O USB audio interface:

The Lexicon I.O 22

The compact baby of the range the I.O22 sports 2 analog combi-jack inputs and 2 analog 1/4″ TRS balanced outputs.

This would suit a small set up where lots of I/O’s are not needed.  A podcaster or solo musician would be completely at home here.  With no fuss or clutter to confuse your workflow.


You can find the specs for the I.O 22 at the Lexicon Pro website here.

You can buy the I/O 22 at Amazon for around £168 / $225 / €259.

The Lexicon I.O 42

Middle of the range, the I.O 42 has 4 analog combi-jack inputs and 2 analog 1/4″ TRS balanced outputs.

It also incorporates a stereo S/PDIF input and output which could be used to send and return from a digital effect unit, or possibly hooked up to a pair of powered monitors (with digital inputs), or straight to digitial mastering.

Personally I would use it to hook up to my Yamaha A4000 for mastering down and sample with.


You can find the specs for the I.O 42 at the Lexicon Pro website here.

You can buy the I/O 42 at Amazonfor around £210 / $289 / €325.

The Lexicon I.O 82

With 8 inputs and 2 output this is the daddy of the range. Also incorporating S/PDIF digital I/O.

If you want to plug in a variety of instruments or equipment at the same time then this is the model for you.

You could quite comfortably accomodate a keyboard, drum machine, sampler and a couple of mics.
