Main PGM Outputs
Standard XLR output connector for the main program mix left &
right outputs.
Wired Pin 1=Chassis, Pin 2=hot (+), Pin 3=Cold (-).
Electronically balanced, nominal level = +4dBu (=0VU).
Main PGM Inserts
Standard 1/4” (6.25mm) Jack socket for unbalanced insert send and
return signals.
Wired Tip=send, Ring=return, Sleeve=Chassis. Nominal level is -
2dBu.
The insert point is pre the main PGM fader.
Output Limiter
The limiter controls are on the rear panel of the XB-10.
Use a matchstick or similar to press both mode switches, this acti-
vates the limiter for the left and right channels respectively. The
trimmer pot can be adjusted with a small bladed screwdriver and this
allows the limiter threshold range to be changed from 0dBu to
21dBu.
The limiter LED will come on as soon as the limiter reaches its
threshold.
Headphone Output Sockets
Standard 1/4” (6.25mm) Jack sockets for the engineer/self operator
and guest.
Wired Tip=Left (+), Ring=Right (-), Sleeve=Ground.
48v Phantom Power switch
Press this in to switch 48v Phantom Power to the 3 Mic input xlr
connectors, if any of the microphones attached require power.
Dynamic microphones won’t mind being connected to a phantom
powered input, but care is needed to ensure that 48v is not switched
on if an xlr is used to input a signal from an electronic circuit (ie. An-
other mixer).
When switching 48v on or off, or plugging in connectors to
channels with 48v present, it is important (and normal pro-
cedure) to mute the channels.
Main Program Level
The main program mix level control. Affects the stereo PGM XLR
outputs and phones feeds, but not the prefade PGM outputs to USB
and RECORD OUT.
0dB, or unity gain is at the top of the control.
