¢ Connections
•With the AVR-687, up to ten 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.

¢ 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.
