Zoom LiveTrak L-20 Digital Mixer/Recorder
The Zoom LiveTrak L-20 is a 20-channel digital mixer that records every channel plus a stereo mix to an SD card and gives the band six custom monitor mixes.
Inputs and Mixing
Sixteen mono channels take XLR or 1/4-inch plugs through combo inputs, with +48 V phantom power, gain up to +60 dB, and an equivalent input noise of -128 dBu. Channels 1 and 2 switch to Hi-Z for electric guitar or bass, and channels 3 to 16 have a 26 dB pad. Two stereo channels take TS or RCA line inputs for keyboards and other sources.
Every channel has a fader, mute and solo buttons, a 3-band EQ with a sweepable mid, and a low-cut filter adjustable from 40 Hz to 600 Hz, and the 16 mono channels add one-knob compression. Two effects buses carry 20 reverb, delay, and chorus effects, and nine scenes recall fader positions, EQ, pan, and mutes.
Each of the six monitor outputs carries its own mix with effects and switches between a powered headphone output and a balanced line output for stage monitors. A seventh headphone output lets the front-of-house engineer hear the main mix or any monitor mix.
Recording
The L-20 records 22 tracks at once, the 20 channels plus a stereo mix, as WAV files at up to 24-bit/96 kHz to SD cards up to 1 TB, and plays back 20. A built-in slate mic records talkback. Effects, EQ, overdub, the audio interface, and the fader modes are not available at 96 kHz.
Interface and Control
Over USB it is a 22-in/4-out audio interface for a DAW or streaming software, even while it records to the SD card. Audio from the computer can also be mixed into the live performance, and class-compliant mode connects iOS devices through Apple’s Lightning to USB Camera Adapter.
With the optional BTA-1 adapter, a free iPad app controls fader levels and modes, scenes, EQ, and effects. The L-20 runs on the included AD-19 AC adapter.
