Easy Setup Procedure Easy Setup Procedure
Connecting the speaker cables
2 Connections
•With the AVR-987, up to 10 speakers can be connected for surround playback.
• When making connections, also refer to the operating instructions of the other components.
When using only one surround back
speaker, connect it to the left channel.

2 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.
1. Loosen by turning
counterclockwise.
Either tightly twist or terminate the
core wires.
2. Insert the cable.
3. Tighten by turning
clockwise.
