Zoom LiveTrak L-20 20-Channel Digital Mixer With 24-bit/96kHz Recorder

Manufacturer’s Description

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.

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.
Engineer with L-20

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.*

Channel Strip

All 20 inputs include a channel fader as well as dedicated mute and solo buttons. The 16 mono inputs include single-knob compression and gain control. Record or playback individual channels with the “Rec/Play” button.

EQ Control

The L-20 provides a smooth 3-band mid-parametric EQ and a variable frequency low-cut for each channel. Use the “Select” button to apply Channel Strip settings to the selected channel.

2 EFX Sends

The L-20 offers 20 built-in effects with adjustable parameters. Choose from delay and reverb effects, then apply them to any channel using two dedicated EFX busses.

Broad Connectivity

The L-20’s combo inputs support XLR or ¼-inch connections. Channels 1-2 offer Hi-Z inputs for electric guitar or bass. Channels 17/18 and 19/20 have TS line connectivity for keyboards and other audio devices, as well as RCA inputs.

Navigation and Display

The LiveTrak L-20’s bright, backlit LCD screen and encoder knob let you access an intuitive menu to create new projects, recall previous projects, and customize your recorder settings.

Slate Mic and Metronome

Use the built-in slate mic to record comments or talk-back. Push the tempo button to program the metronome to your desired tempo.

Transport Controls and Overdub Button

Transport controls include Record, Play/Pause, Stop, Fast Forward, and Rewind. The overdub button allows you to record additional tracks to your current project.

Six Custom Monitor Mixes

The “Fader Mode” buttons allow you to design custom mixes for both the master and monitor outs. For each output, easily switch between a powerful headphone output and a balanced line output for stage monitors.

Headphone Output for FOH

The L-20 includes a dedicated headphone output for front-of-house, enabling them to monitor any of the custom sub mixes as well as the master mix.

Custom Scene Settings

Create and save up to nine different scenes to recall fader position, EQ settings, pan, mute, and more.
