NOTE: When making connections, take care that none of the individual conductors of the speaker cable come in contact with adjacent terminals, with other speaker cable conductors, or with the rear panel and screws. NEVER touch the speaker terminals when the power is on. Doing so could result in electric shocks. Connecting the speaker cables 1. Loosen by turning counterclockwise. 2. Insert the cable. Either tightly twist or terminate the core wires. 3. Tighten by turning clockwise. ¢ Speaker impedance Speaker A, B A+B Impedance 4 ~ 16 Ω/ohms 8 ~ 16 Ω/ohms Note on speaker impedance When using speakers with an impedance below the designated value (for example 4 Ω/ohms), playing for long periods of time with the volume high could cause the temperature to rise, activating the protection circuit. When the protection circuit is activated, the output to the speakers is cut off and the power indicator blinks. If this happens, unplug the power cord, wait for the set to cool off and improve ventilation around the unit. Also check the wiring of the input cables and the speaker cables. After doing this, plug the power cord back in and turn the unit's 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.

Speaker impedance
Note on speaker impedance
When using speakers with an impedance
below the designated value (for example 4
Ω
/ohms), playing for long periods of time with
the volume high could cause the temperature
to rise, activating the protection circuit.
When the protection circuit is activated, the
output to the speakers is cut off and the power
indicator blinks. If this happens, unplug the
power cord, wait for the set to cool off and
improve ventilation around the unit. Also check
the wiring of the input cables and the speaker
cables. After doing this, plug the power cord
back in and turn the unit’s 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:
When making connections, take care that
none of the individual conductors of the
speaker cable come in contact with adjacent
terminals,
with
other
speaker
cable
conductors, or with the rear panel and
screws.
NEVER touch the speaker terminals when
the power is on. Doing so could result in
electric shocks.
