each channel of the EMX660 and the 
MASTER control of the MAIN section are 
turned down.

While speaking into the mic (while play-
ing the instrument), adjust the channel 
LEVEL control so that the 0 LED of the 
MAIN section peak level meter lights 
occasionally.
Repeat this step for each channel.

MONITOR OUTPUT, you can create a monitor 
mix independent of the MAIN mix, since the 
input channel MONI controls are not affected by 
the LEVEL controls.

Note:   

When turning the power off, reverse this 

sequence.

Note:   

If the effect sound is distorted even if the 

EFFECT RTN turned all the way down, lower 
the EFFECT controls of each channel.
