Speaker impedance

Use speakers with impedances within the ranges shown below to suit how they are used.

Speakers used Impedance

A or B 4 – 16 Ω

A and B 8 – 16 Ω

Bi-wiring connection 4 – 16 Ω

Protection circuit

The protection circuit is be activated in the following situations:

•If the speaker cable wire touches the rear panel or screws or if the speaker cable wire touches the

speaker cable’s + and – sides are touching

•If the surrounding temperature is extremely high

•If the inside of the ampliﬁer gets hot to extended use at a high output

If this happens, unplug the power cord, then check the connections of the speaker cables and input cables.

If the unit becomes very hot, wait for it to cool off and improve the ventilation around it. After doing this,

plug the power cord back in.

If the protection circuit is activated even though there are no problems with the ventilation around the unit

or in connections, the unit may be damaged. Turn off the power and then contact a DENON service center.
