Controls and Functions
Power Amp Section
The XML series of mixers have a power amplifier section which 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 XML series' power amp modes.
38. POWER - The POWER indicator lights to indicate that the power in on.
39. Power Amp MODE switch - The MODE switch is used to select one of the
following operating modes: MAIN-MONITOR, MAIN-MAIN or MAIN-BRIDGE
(XML410 only).
CAUTION! Only change the power amp MODE switch when the 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 MAIN
(XML410) or MAIN (L+R) (XML610 and XML910), and the MONITOR bus
signal will be sent from the MONITOR jacks.
MAIN-MAIN - With this setting, the two power amp channels can be used
independently. The MAIN bus signal will be output from the MAIN MODE
(XML410) or RIGHT/LEFT jacks (XML610 and XML910 Rear Panel).
MAIN-BRIDGE (XML410 only) - 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.
40. LOW ENHANCE (XML610 and XML910) - This switch turns on or off the LOW
ENHANCE processing on and off. The LOW ENHANCE boosts the low frequen-
cies at the speaker outputs. Use the LOW ENHANCE for added bass in situa-
tions where you do not have subwoofers.
41. MUTE CH 1–8 (XML610 and XML910) - You can turn off channels 1–8 on the
XML610 or XML910 using the MUTE CH 1–8 switch. This feature is convenient
to use 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 1–8 does not
turn off channels 9/10, and 11/12, and does not turn off the CD/TAPE inputs.
