Easy Setup and Operation Easy Setup and Operation
2 Connections
• The AVR-4306 can be configured for 10 speaker playback using two pairs of surround speakers
(A+B) and one pair of surround back speakers as shown below.
• The output of the surround back’s power amplifier can be assigned to the multi zone or front
channel.
For details, refer to “Setting the Power Amplifier Assignment” (
page 76).
• When making connections, also refer to the operating instructions of the other components.
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.

Speaker 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 stereo image being impaired.
2 Speaker impedance
• Speakers with an impedance of from 6 to 16
Ω /ohms can be connected for use as front,
center, surround and surround back 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.
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
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.
NOTE:
NEVER touch the speaker terminals
when the power is on. Doing so could
result in electric shocks.
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
and screws.
1. Loosen by turning
counterclockwise.
Either tightly twist or terminate
the core wires.
2. Insert the cable.
3. Tighten by turning
clockwise.
Turn clockwise to tighten,
then insert the banana plug.
