Protector circuit

• This unit is equipped with a high-speed protection circuit. The purpose of this circuit is to protect the speakers under

circumstances such as when the output of the power amplifier is inadvertently short-circuited and a large current flows,

when the temperature surrounding the unit becomes unusually high, or when the unit is used at high output over a long

period which results in an extreme temperature rise.

When the protection circuit is activated, the speaker output is cut off and the power supply indicator LED flashes. Should

this occur, please follow these steps: be sure to switch off the power of this unit, check whether there are any faults with

the wiring of the speaker cables or input cables, and wait for the unit to cool down if it is very hot. Improve the ventilation

condition around the unit and switch the power back on.

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.
