THe eFFeCTS LOOP

The Key-Largo is equipped with an effects loop to allow you to share 

outboard effects units across all of your keyboards. This feature can 

be used with both mono and stereo effects, as well as with pedals or 

rackmount equipment. A latching footswitch turns the loop on and off, 

so you can quickly add in a delay or a chorus and have it affect each 

keyboard as much or as little as you want.

For mono effects, engage the recessed switch on the left side of the Key-

Largo. Then connect the SEND jack to the input of your effects unit, and 

the output to the RECV jack using ¼” TS coaxial cables.  

For stereo pedals and effects, make sure that the recessed Effects 

switch is disengaged. Use insert cables wired with ¼” TRS to 2x ¼” TS 

connectors to connect the SEND jack to the left and right inputs of the 

effects unit, and use a second insert cable to connect the outputs of the 

device to the TRS RECV connector on the Key-Largo. 

Mono

Stereo

Start with the EFX RECV level control at 12 o’clock, this controls how 

much of the overall FX you will hear in the mix. Engage the EFFECTS 

footswitch on the Key-Largo and slowly turn up the EFX SEND control on 

each channel that you want to send to the effects loop. The EFX SEND 

controls follow the input level controls in the signal chain, so if you turn 

down CH-1 LEVEL, you’ll also be reducing the amount of signal sent to 

the EFX SEND on channel 1. Note that when the Key-Largo is set to 

Recording mode, the EFX SEND for the USB input will not be active.
