Mode-Power amp Mode switch
The MODE switch is used to select one of
three different operating modes, MAIN-
MONITOR, MAIN-MAIN and MAIN-
BRIDGE. The following is a description of
each of the POWER operating modes:
CAUTION! Only change the power amp
mode switch when the XM910’s power
is SWITCHED OFF!
MAIN-MONITOR
With this setting, the MAIN and MONITOR
sections can be used independently. The
MAIN bus signal will be sent from the
POWER AMP 2 A/B jacks, and the MONI-
TOR bus signal will be sent from the POWER AMP 1 A/B jacks.
MAIN-MAIN
With this setting, the two power amp channels can be used independently. The MAIN bus signal will be
output from the POWER AMP 2 A/B jacks (Rear Panel), and also, from the POWER AMP 1 A/B jacks .
MAIN-BRIDGE
With this setting, the two power amp channels (1 and 2) will be connected in bridge mode. Only the MAIN
bus signal will be output from the BRIDGE jack.
Phantom Power - Switch
The XM910 features an onboard, 48-Volt Phantom power supply to operate condenser microphones.
When the switch is engaged, the LED will illuminate indicating that phantom power is now available on the
microphone pre-amps.
IMPORTANT NOTE:
To avoid a loud pop, be sure to turn down the MASTER level controls before plugging
and unplugging the mic cables when the phantom power is active.
Mute CH 1 - 6 - Switch
You can turn off channels one through six with a press of a single button using the MUTE CH 1 – 6 switch.
This is especially convenient when you take a break and want to leave all the levels set so they are ready
when you begin to use your PA system again. The MUTE 1-6 does not turn off channels 7/8 and 9/10,
and does not turn off the CD/TAPE inputs. So, when the MUTE CH 1 – 6 switch is on, you still have a 2
channel DJ mixer with two available mic inputs.
Controls and Functions
POWER AMP SECTION
The XM910’s power amplifier section can be configured to operate several ways depending on whether you need
MAIN plus MONITOR amplifiers to power your speakers, or if you just need more power for the MAIN speakers.
The section below describes the XM910 power amp modes.
