Enter the era of live mixing and recording where everyone is the master of their mix with Zoom's LiveTrak™ L-20R rack-mountable digital mixer. This portable mixer allows musicians to do it all - control their live mix right from the stage. 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. Mix remotely, record directly.

The LiveTrak L-20R is a robust 22-in/4-out USB audio interface that routes inputs to any DAW, streaming software, or iOS device*—even while recording to an SD card. Featuring 16 mono mic/line inputs and two stereo inputs, the L-20R can handle the most demanding stages. The L20R offers two EFX busses and each channel includes a 3-band EQ, pan controls and compressor. 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.

With six independent monitor outputs, the LiveTrak L-20R enables musicians to wirelessly create their own custom mix. A dedicated output enables the FOH engineer to easily switch between monitoring the main and sub mixes. With iPads, the FOH engineer and 6 musicians can control their own mix, including fader levels, EQ settings, channel effects, and more from anywhere in the venue.
