q Power switch
Turns power to the unit ON or OFF. Setting the switch to the
upward position turns the power on; the [POWER] indicator
!0 will light green. Setting the switch to the downward posi-
tion turns the power off. If the switch is in the upward posi-
tion and the [POWER] indicator is flashing, the unit is in
standby mode.
CAUTION
• To ensure that high-volume noise is not output from
the speakers, power-on the equipment starting with
the audio sources, then the mixer and processors
(such as the MTX), and finally the amplifiers. Reverse
this order when turning the system off.
• Rapidly turning the power switch ON and OFF in suc-
cession can cause the unit to malfunction. After turn-
ing the power switch OFF, wait for about 5 seconds
before turning it ON again.
• If you modified parameter settings, do not turn the
power switch OFF for at least one second. Otherwise,
the changes to the settings may be lost.
• Even when the power switch is turned off, a small
amount of current is flowing through the unit. If you
plan not to use the unit for a long period of time,
remove the power cable from the AC outlet.

w [PROTECTION] A/B/C/D indicators
When the protection system is active, the indicator will light
orange. If the audio output is muted, turn off the power and
wait for the XMV to cool before turning the power on again.
The protection circuit will operate and the [PROTECTION]
indicator will light in the following situations.
If the amplifier overheats and the output lim-
iter operates
The speaker output will be attenuated if the heat sink of
the amplifier section exceeds 80°C, and will be muted if
the heat sink exceeds 90°C. The [PROTECTION] indica-
tor will light at 80°C or higher.
If the power supply overheats and shuts-down
The fan will rotate at high speed if the power supply sec-
tion exceeds 90°C, and the analog circuits will shut down
if it exceeds 100°C.
The [PROTECTION] indicator will light at 100°C or
higher.
