Before using
Pay attention to the following before using this
unit:
• Moving the unit
To prevent short-circuits or damaged wires in
the connection cables, always unplug the power
supply cord and disconnect the connection
cables between all other audio components
when moving the unit.
• Before turning the power switch on
Check once again that all connections are
correct and that there are not problems with
the connection cables. Always set the power
switch to the standby position before
connecting and disconnecting connection
cables.
• Store these instructions in a safe place.
After reading, store this instructions along with
the warranty card in a safe place.
• Note that the illustrations in these
instructions may differ from the actual unit
for explanation purposes.
• V. AUX terminals
The AVR-686’s front panel is equipped with V.
AUX terminals. Remove the cap covering the
terminals when you want to use them.
Cautions on installation
Noise or disturbance of the picture may be
generated if this unit or any other electronic
equipment using microprocessors is used
near a tuner or TV.
If this happens, take the following steps:
• Install this unit as far away as possible
from the tuner or TV.
• Run the antenna wires from the tuner or
TV away from this unit’s power supply cord
and input/output connection cables.
• Noise or disturbance tends to occur
particularly when using indoor antennas or
300 Ω/ohm feeder wires. We recommend
using outdoor antennas and 75 Ω/ohm
coaxial cables.

Note
Cautions on handling
• Switching the input source when input terminals are not connected.
A clicking noise may be produced if the input source is switched when nothing is connected to
the input terminals. If this happens, either turn down the MASTER VOLUME control knob or
connect components to the input terminals.
• Muting of PRE OUT terminals, PHONES jack and SPEAKER terminals.
The PRE OUT terminals, PHONES jack and SPEAKER terminals include a muting circuit. Because
of this, the output signals are greatly attenuated for several seconds after the power switch is
turned on or the input source, surround mode or any other set-up is changed. If the volume is
turned up during this time, the output will be very high after the muting circuit stops functioning.
Always wait until the muting circuit turns off before adjusting the volume.
• Whenever the power switch is in the STANDBY state, the unit is still connected to AC line
voltage.
Please be sure to turn off the power switch or unplug the cord when you leave home for,
say, a vacation.
Preparing the remote control unit
The included remote control unit (RC-1001) can be used to operate not only the AVR-686 but other
remote control compatible DENON components as well. In addition, the memory contains control
signals for other remote control units, so it can be used to operate non-DENON remote control
compatible products.
Note:
For heat dispersal, do not install this unit in a confined space such as a bookcase or similar
enclosure.
