Overview |
The Zoom LiveTrak L-20R is a
rack-mountable digital mixer that allows musicians to control their live
mix right from the stage. With wireless control, 20 discrete channels,
22 tracks of recording and six custom monitor mixes, the L-20R offers a
complete solution for any venue.
Featuring 16 mono mic/line inputs and two stereo inputs, the L-20R can
handle the most demanding stages. The L-20R offers two EFX busses and
each channel includes a 3-band EQ, pan controls and compressor. During
your live performance, record 20 channels plus a stereo mix directly to
an SD card, then transfer your tracks to your DAW for your final edit.
With six independent monitor outputs, the L-20R enables musicians to
create their own custom mix. A dedicated output enables the FOH engineer
to easily switch between monitoring the main and sub mixes.
With iPads, the FOH engineer and 6 musicians can control their own mix,
including fader levels, EQ settings, channel effects, and more from
anywhere in the venue. With the LiveTrak L-20R’s Scene Recall feature,
you can instantly recall up to nine different scenes with monitor mixes,
EQ settings, effects, and more.
The L-20R is a 22-in/4-out USB audio interface. Route inputs to any DAW,
streaming software, or iOS device—even while recording to an SD card. |
