Mono Input channel 1
Rear panel features (continued):
Split-Out XLR jack
This male XLR jack is wired pin-to-pin to the female XLR input jack.In combination with
the female XLR,it forms a passive,Y-Split of the input signal.This split-signal can be used to feed
the mic input to another mixer (usually the FOH mixer),or to “mult” the input to another chan-
nel on the XRM.
NOTE:This pin-to-pin connection between XLR jacks is NOT affected by the Pin-1 lift switch.
ChanInser t jack
This switching 1/4” TRS jack allows an external signal processor to be inserted into the
signal path of the channel.The tip carries the SEND signal from the channel,and the ring carries
the RETURN signal back to the channel.The insert-send point is located directly after the Lo-Cut
filter on the channel,the return comes back into the channel at the top of the EQ section.
Tip is Send,Ring is Return, Sleeve is Audio Ground.
Send (output) impedance is 50Ω
Return (input) impedance is 5KΩ
Nominal Operating Level= +4dBu
NOTE: To avoid any degradation of the XRM’s channel signal,any processing gear patched into
the channel insert should have a low impedance output (<100Ω) and must be capable of cleanly
driving a 2KΩload to +21dBu.
T= Send
R= Return
S= GND
