Speaker Impedance
Speakers with an impedance of from 6 to 16
/ohms can be connected for use as front and
center speakers.
Speakers with an impedance of 6 to 16 /ohms
can be connected for use as surround and surround
back speakers.
Be careful when using two pairs of front speakers
(A + B) at the same time, since use of speakers
with an impedance of less than 8 /ohms will lead
to damage.
The protector circuit may be activated if the set is
played for long periods of time at high volumes
when speakers with an impedance lower than the
specified impedance are connected.
NOTE:
NEVER touch the speaker terminals when the
power is on.
Doing so could result in electric shocks.
Connecting the speaker cords
1. Loosen by turning
counterclockwise.
2. Insert the cord. 3. Tighten by turning
clockwise.
Speaker system connections
Connect the speaker terminals with the speakers
making sure that like polarities are matched ( <
with < , > with > ). Mismatching of polarities will
result in weak central sound, unclear orientation of
the various instruments, and the sense of direction
of the stereo being impaired.
When making connections, take care that none of
the individual conductors of the speaker cord come
in contact with adjacent terminals, with other
speaker cord conductors, or with the rear panel.
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 LED
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 set is played 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 lower than 4 /ohms) are connected. If the protector circuit is activated, the speaker output
is cut off. Turn off the set’s power, wait for the set to cool down, improve the ventilation around the set,
then turn the power back on.
Either tightly twist or terminate the core wires.
Connecting banana plugs
(Taiwan R. O. C. model only)
banana plug
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
have this effect.
SURROUND SPEAKER
SYSTEMS
SURROUND BACK/ZONE 2 SPEAKER SYSTEMS
NOTES:
•To use Surround back with one
speaker, connect the speaker to
SURR. BACK L CH.
The settings must be changed to
use this speaker for ZONE 2.
