CHANNEL INPUT Balanced XLR input pin 2 hot. Accepts
microphone or line level signals. For very hot mic or for line signals press
the channel PAD (LINE) switch. For unbalanced sources use a cable or
adapter that connects XLR pin 3 to pin 1.
WARNING: Do not connect unbalanced sources or cables to
the XLR input when 48V phantom power is selected. To avoid loud
clicks always turn the channel off by pressing MUTE when switching
+48V on or off, and when plugging or unplugging cables.
BUILT-IN MIC SPLITTER A passive splitter passes each channel
XLR input directly through to an XLR output to send the signal to another
console such as Front-of-House or recording. The mic signal can feed the
monitor and the FOH console at the same time. Connect the split outputs
to the multicore feeding the FOH console using XLR cables.
NOTE: Phantom power can be switched from either the monitor or
the FOH console. If switched from FOH then make sure GND LIFT is
not selected. If it is necessary to select GND LIFT then phantom
power should be switched from the monitor console. No harm will be
done to the consoles if phantom power is switched from both
consoles at the same time.
GND LIFT Disconnects the pin 1 ground connection between the input
XLR and the split output XLR. Press this if there is a problem with a
venue ground loop causing audible hum when connecting the splitter to
the second console. A single ground lift switch is provided next to CH1
input. This affects the ground connection to all the channel split outputs.
