XLR
Buffered post effects, post EQ signal for studio or stage use.

the standards for audio. Pin 1 is shield, Pin 2 is signal plus, and
Pin 3 is signal minus.

GND Lift
This switch allows you to disconnect Pin 1 of the XLR connector
from the chassis ground. It is seldom necessary in properly built
equipment, but might be needed sometime. Leave in the Norm
(In) position unless needed.
EFX Send Level
This adjusts the level to your effects unit. This will allow you to
have enough of a signal to make the effects work well and yet not
overdrive it.
EFX Send Jack
Mono send to parallel mode effects unit input. Use a ¼ inch TS
(tip, sleeve) phone plug.
EFX Return
This is a mono (TS) input from your effects unit mono output.
EFX Return Level
This potentiometer allows you to select the nominal signal level
coming from your effects unit, it is adjustable from +4dB to less
than -30dB. Most “Pro” equipment is u4dB while
consumer equipment is usually -10dB.
