Overview
The Key-Largo is a compact keyboard mixer that also includes the real-
time performance attributes of a footswitch controller, allowing you to
easily create an exciting and professional performance on stage. The
best way to approach the various features of this powerful device is to
break each section down into modules before addressing the Key-Largo
as a whole.

The design begins with ¼” TS (tip-sleeve) inputs that allow you to
connect up to three stereo keyboards at once. The Key-Largo has
tons of headroom so it can handle your hottest keyboard outputs,
and it features individual level controls to balance the signal levels
of each instrument. For mono keyboards, simply connect to the left
input only – the Key-Largo will automatically route the signal to both
the left and right outputs.
USB
In addition to functioning as a mixer, the Key-Largo is also a high-
quality USB audio interface. This means you can connect to your
laptop to play back soft synths or other backing tracks. This connec-
tion can also be used to record your performance using your digital
audio workstation of choice.
eFFeCTS
The Key-Largo effects loop lets you share your favorite pedal or
rackmount effects unit across all of your keyboards. This can be used
with mono or stereo effects, and is easily activated/deactivated with
a built-in footswitch. EFX SEND/RECV knobs provide precise control
over which channels feed the effects loop, as well as how much of
the effects return is blended with the dry signal from your keyboards.
MONiTOrS
Balanced ¼” TRS monitor outputs provide the option to connect to
a pair of powered speakers for easy on-stage monitoring. A level
control lets you adjust the volume to suit, and a ground lift switch is
provided to help reduce noise from ground loops.
MAiN OUT
The main outputs of the Key-Largo are balanced XLRs for connec-
tion to a console or PA system. They feature transformer isolation to
eliminate buzz and hum, as well as a ground lift switch for additional
noise abatement.
