Zoom LiveTrak L-20 - 20-Input Digital Mixer & Multitrack Recorder

The highly flexible Zoom LiveTrak L-20 is a 20-input digital mixer and multi-track recorder, well suited for live performances, studio recording, band rehearsals, podcasts, and more. The mixer features 16 mono channels, each with combo mic/line XLR-1/4" inputs with high gain, low-noise microphone preamps, +48V phantom power, and a single compression knob, while the two stereo inputs offer dual 1/4" and RCA inputs. Channels 1-2 also offer Hi-Z inputs for connecting guitars and basses. All channels work with the on-board channel strip, which provides a low-cut filter, a 3-band EQ, a pan control, and two send FX for sending signals to the 20 built-in high-quality effects processor with two dedicated EFX Return channels.

The LiveTrak L-20 features balanced XLR main outputs, while the six monitor outputs utilize balanced TRS 1/4" connectors, each with the ability to set up customized mixes. Simply connect your headphones or a stage monitor and adjust the levels to taste. There are nine snap-shot presets, which allow you instant recall of different setups and sessions.

The built-in SD recorder can simultaneously record every channel and the master fader stereo signal output for a total of 22 tracks at resolutions up to 24-bit/ 96 kHz. Files can easily be copied to a computer and used in a DAW. In addition, overdubbing and punching in/out can be done as expected when using the unit as a multi-track recorder. The L-20 can also function as a 22-in/4-out USB audio interface, allowing you to record directly to your favorite software DAW or to iOS devices. Other notable features include 12-segment LED meters on all channels, a built-in metronome, and a built-in slate mic for identifying takes. The Zoom LiveTrak L-20 ships with a power cord and a USB cable.
