With wireless control, 20 discrete channels, 22 tracks of recording and six custom monitor mixes, the L-20R offers a complete solution for any venue

Portable and Powerful

Featuring 16 mono mic/line inputs and two stereo inputs, the L-20R can handle the most demanding stages. The L-20R offers two EFX busses and each channel includes a 3-band EQ, pan controls and compressor.

22 Tracks of Recording

During your live performance, record 20 channels plus a stereo mix directly to an SD card, then transfer your tracks to your DAW for your final edit.

It’s Your Monitor Make It Your Mix

With six independent monitor outputs, the L-20R enables musicians to create their own custom mix.

A dedicated output enables the FOH engineer to easily switch between monitoring the main and sub mixes.

iPad Control

With iPads, the FOH engineer and 6 musicians can control their own mix from anywhere in the venue.

Scene Recall

With the LiveTrak L-20R’s Scene Recall feature, you can instantly recall up to nine different scenes with monitor mixes, EQ settings, effects, and more.

Accessible

The L-20R’s versatile design provides easy access for plugging in your cables.

A Robust Audio Interface

The L-20R is a 22-in/4-out USB audio interface. Route inputs to any DAW, streaming software, or iOS device*—even while recording to an SD card.

Channel Strip

The 16 mono inputs include single-knob compression and gain control. At -128 dBu EIN with +60 dB maximum input gain, the L-20R is equipped with our quietest and most advanced preamps.

Navigation and Display

An encoder knob and bright, backlit LCD screen let you access an intuitive menu to create new projects, recall previous projects, and customize your recorder settings.

Bluetooth Adapter

The included BTA-1 connects a master iPad to the L-20R. Other iPads connect to the master via wifi.

Transport controls include Record, Play/Pause, and Stop. The overdub feature allows you to record additional tracks to your current project.

Six Custom Monitor Mixes

“Master” and “Headphone” options allow you to design custom mixes for both the master and monitor outs. For each output, easily switch between a powerful headphone output and a balanced line output for in-ear and stage monitors.

Headphone Output for FOH

A dedicated headphone output for front-of-house enables the engineer to monitor any of the custom sub mixes as well as the master mix or soloed tracks.
