Zoom LiveTrak L-20 20-channel Digital Mixer / Recorder

Zoom LiveTrak L‑20 20-Inpbajut Digital Mixer Overview:

The LiveTrak L-20 is the new digital console offering everything creators need to mix, monitor, and record complex productions. With 20 discrete audio channels and six individual custom monitor mixes, it’s built for bigger, bolder arrangements.

20 Inputs for Bigger Sound

The LiveTrak L-20 is designed to mix bigger. It features 20 inputs (16 mono mic/line inputs and two stereo inputs), all with independent 3-band mid-parametric EQ. The 16 mono inputs offer stand-alone compressor control.

22 Tracks of Recording

Record 20 discrete channels plus a stereo mix directly to an SD card. The LiveTrak L-20 captures pristine audio in resolutions up to 24-bit/96 kHz.* At -128 dBu EIN with +60 dB maximum input gain, the L-20 is equipped with our quietest and most advanced preamps ever. Mix down finished songs on the L-20 or transfer your discrete tracks to a DAW to perfect later.

*Effects, EQ, overdub, audio interface, and fader modes A-F are not available in 96 kHz.

Create Six Custom Monitor Mixes

With six independent monitor outputs for musicians, each output can have its own custom mix, complete with effects, that can easily be switched from a powerful headphone output, to a balanced line output for stage monitors.

And One for the House

The LiveTrak L-20 features a dedicated 7th output for the FOH engineer. The sound engineer can monitor the main mix and any of the sub mixes, thus adjusting them to the musicians’ satisfaction.

Big Beautiful Interface

Although the LiveTrak L-20 is designed to work as a stand-alone recording and mixing console, it can also be used as a 22-in/4-out USB audio interface. Audio Interface mode lets you route inputs to any DAW or streaming software, even while recording to an SD card. Additionally, audio can be routed from your computer into the L-20 to be mixed with your live performance. Class compliant mode, which enables connection with iOS devices, is supported as well.*

*Apple Lightning to USB Camera Adapter required.

Wireless Mixing

The LiveTrak L-20 offers wireless control* via a free iOS mobile app "L-20 Control" featuring most onboard functions, including Fader Levels and Modes, Scenes, EQ, EFX sends, returns, and parameters, and more. You can even manage your Effects Library and Scene Library right from your device. Control it all on either large Monitor Out view with a mini transport, or a mini Monitor Out view with expanded Transport controls.

* Zoom Bluetooth adapter (ex. BTA-1) required. Communication at up to 10 meters is possible in an unobstructed indoor space with BTA-1 units.
