Zoom LiveTrak L-20R Rack-Mount Digital Mixer/Recorder
With 20 channels, six monitor mixes, and 22-track recording to an SD card, the Zoom LiveTrak L-20R is a rack-mount digital mixer and recorder.
Sixteen mono channels take XLR or 1/4-inch plugs through combo inputs, each with one-knob compression, gain up to +60 dB, a pad, and +48 V phantom power, with an equivalent input noise of -128 dBu. A Hi-Z setting takes instruments, and two stereo channels take TS or RCA line inputs for keyboards and other sources.
Every channel has a 3-band EQ with a sweepable mid from 100 Hz to 8 kHz, a low-cut filter adjustable from 40 Hz to 600 Hz, and pan. Sends feed two effects buses with 20 reverb, delay, and chorus effects. Each of the six monitor outputs switches between a powered headphone output and a balanced line output for in-ear or stage monitors. A separate headphone output lets the front-of-house engineer hear any mix or soloed tracks, and nine scenes recall monitor mixes, EQ, and effects.
The included BTA-1 adapter connects a master iPad, other iPads connect to it over Wi-Fi, and the engineer and six musicians can each control their own mix from anywhere in the venue. The L-20R records 22 tracks, 20 channels plus a stereo mix, as WAV files at up to 24-bit/96 kHz to SD cards up to 1 TB, with overdub. Effects, EQ, overdub, the audio interface, and fader modes are not available at 96 kHz.
Over USB it is a 22-in/4-out audio interface for a DAW, streaming software, or iOS devices with Apple’s Lightning to USB Camera Adapter, even while it records to the SD card. Rack ears come in the box, and the L-20R runs on the included AD-19 AC adapter.
