• The AV surround amplifier (AVC-M330) is equipped with a built-in protection circuit. The purpose of this circuit is to cut off the output to the
speakers in order to protect them under circumstances such as when the output of the amplifier is inadvertently short-circuited and a large
current flows or when there is an extremely large output.
The protection circuit is also activated when the internal temperature is unusually high. (When the protection circuit is activated due to high
internal temperature, the volume indicator flashes and the speaker output is restricted. If the internal temperature rises further, the power
is set to the standby mode and the power indicator flashes red.) In such cases, be sure to unplug the AV surround amplifier’s power cord
from the power outlet, check the wiring of the connection cords and input cords for any abnormalities, and if the AV surround amplifier’s
temperature is extremely high, wait for it to cool down, improve ventilation around the amplifier, then turn the power back on.
If the protection circuit is activated even though there are no problems with the wiring or with ventilation around the AV surround amplifier,
there may be a problem with the AV surround amplifier. Unplug the AV surround amplifier’s power cord from the power outlet, then contact
a DENON service or repair center.
Protector circuit
•The protector circuit may be activated if the set is played for long periods of time at high volumes when speakers with an impedance lower
than the specified impedance (for example speakers with an impedance of lower than 4 Ω/ohms) are connected. If the protector circuit is
activated, the speaker output is cut off. Turn off the set’s power, wait for the set to cool down, improve the ventilation around the set, then
turn the power back on.
Note on speaker impedance
Replacing the speaker connection cords
• The speaker connection cords can be replaced, for example when you want to extend the included connection cords.
q Press the release button on the side opposite the lock level to
detach the cord from the plug.
w Peel off the sheathing at the tip of the cord you want to replace,
and twist firmly so the tip remains tightly wound.
e Pressing the release button, insert the core wires, making sure to
match the cord’s “+” and “–” polarities with the “+” and “–” sides
of the plug.
r Release the release button, then gently pull on the cord to check
that it is firmly attached.
