Protector circuit
•
This unit is equipped with a high-speed protection circuit. This circuit protects the internal circuitry from damage due to
large currents flowing if the speaker jacks are not completely connected or if an output is generated by a short circuit.
In such a case, the protection circuit will operate to cut off the output to the speakers. Should this happen, turn the
power off and check the speaker connections. Then turn the power on again. After muting for several seconds, the
receiver should be operating normally.
If the protection circuit is activated again even though there are no problems with the wiring or the ventilation around
the unit, switch off the power and contact a DENON service center.
Note on speaker impedance
•
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.
