Speaker Impedance

• Speakers with an impedance of from 6 to 16

Ω/ohms can be connected for use as front and

center speakers.

• Speakers with an impedance of 6 to 16 Ω/ohms

can be connected for use as surround speakers.

• Be careful when using two pairs of surround

speakers (A + B) at the same time, since use of

speakers with an impedance of less than 8 Ω/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 terminals

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.

Either tightly twist or terminate the core wires.

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.

Connections

• When making connections, also refer to the operating instructions of the other components.

SYSTEMS (A)

• 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 BACK/MULTI ZONE 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 ZONE2/ZONE3.

See page 26.
