Speaker connections
•Connect the speaker terminals with the
speakers making sure that like polarities are
matched (
<
with
<
,
>

). Mismatching
of polarities will result in weak central sound,
unclear orientation of the various instruments,
and the stereo image being impaired.
• 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.
2 Speaker impedance
• When speaker systems A and B are used
separately, speakers with an impedance of 6
to 16 Ω/ohms can be connected for use as
front speakers.
• Be careful when using two pairs of front
speakers (A + B) at the same time, since
speakers with an impedance of 12 to 16
Ω/ohms in this case must be used.
• Speakers with an impedance of 6 to 16
Ω/ohms can be connected for use as center
and surround and surround back speakers.
• The protector circuit may be activated if the
unit is operated for long periods of time at
high volumes when speakers with an
impedance lower than the specified
impedance are connected.
Protector circuit
This unit is equipped with a high-speed
protection circuit. The purpose of this circuit
is to protect the speakers under circumstances
such as when the output of the power
amplifier is inadvertently short-circuited and
a large current flows, when the temperature
surrounding the unit becomes unusually
high, or when the unit is used at high output
over a long period which results in an
extreme temperature rise.
When the protection circuit is activated, the
speaker output is cut off and the power
supply indicator flashes. Should this occur,
please follow these steps: be sure to switch
off the power of this unit, check whether
there are any faults with the wiring of the
speaker cables or input cables, and wait for
the unit to cool down if it is very hot.
Improve the ventilation condition around the
unit and switch the 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 on speaker impedance
The protector circuit may be activated if the
unit is operated for long periods of time at
high volumes when speakers with an
impedance lower than the specified
impedance (for example speakers with an
impedance of less than 4 Ω/ohms) are
connected. If the protector circuit is
activated, the speaker output is cut off. Turn
off the unit’s power, wait for the unit to cool
down, improve the ventilation around the
unit, then turn the power back on.
NOTE:
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.
3. Tighten by turning
clockwise.
Connecting banana plugs
Turn clockwise to
tighten, then insert
the banana plug.

Precautions when connecting speakers:
If a speaker is placed near a TV or video
monitor, the colors on the screen may be
disturbed by the speaker’s magnetism. If
this should happen, move the speaker away
to a position where it does not cause this
effect.
NOTE:
• When using only one surround back
speaker, connect it to the left channel.

playback effect, use a unit
that can sufficiently reproduce
frequencies of under 80 Hz.
