The Zoom LiveTrak™ L-20R is a rack-mountable digital mixer that allows musicians to control their live mix directly from the stage using 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. 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 buses, and each channel includes a 3-band EQ, pan controls, and a 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 final editing. With six independent monitor outputs, the L-20R enables musicians to create their own custom mix.
