The Zoom LiveTrak™ L-20R is a rack-mountable digital mixer that allows musicians to control their live mix right from the stage with the use of an iPad. 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

CHANNEL STRIP (A)
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 (B)
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 (C)
The included BTA-1 connects a master iPad to the L-20R. Other iPads connect to the master via wifi.

TRANSPORT CONTROLS AND OVERDUB (D)
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 (E)
“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 (F)
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.

USB PORT (G)
The L-20R features USB connectivity for transferring files or use as an audio interface.

SD CARD (H)
Record up to 512GB of audio to an SD card.
