

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

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.
