The XLR connector is wired to

from the chassis ground. It is seldom necessary in properly built
equipment, but might be needed sometime. Leave in the Norm

have enough of a signal to make the effects work well and yet not
overdrive it.

Mono send to parallel mode effects unit input. Use a ¼ inch TS
(tip, sleeve) mono 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.
