Easy Setup Procedure

Speaker connections

Connect the speaker terminals with the speakers making sure that like polarities are matched (< with <, > with >).

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.

Either tightly twist or terminate the core wires.

2. Insert the cable.

3. Tighten by turning clockwise.

Note on speaker impedance

When using speakers with an impedance below the designated value (for example 4 /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.

¢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.

Connecting banana plugs

Turn clockwise to tighten, then insert the banana plug.

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.
