ENGLISH
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.
NOTE:
NEVER touch the speaker terminals when the
power is on.
Doing so could result in electric shocks.
1. Loosen by turning
counterclockwise.

Connection jack for subwoofer with
built-in amplifier (super woofer), etc.
To achieve Dolby Digital (AC-3)
playback effect, use a unit that can
sufficiently reproduce frequencies
of under 80 Hz.

Speaker Impedance
• When speaker systems A and B are use 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 use of speakers with
an impedance of 12 to 16 Ω/ohms.
• Speakers with an impedance of 6 to 16 Ω/ohms can
be connected for use as center and surround speakers.
• 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.
Connecting the speaker cords
2. Insert the cord. 3. Tighten by turning
clockwise.

• Precautions when connecting
speakers
( L ) ( R )
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.
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 Ω/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.
