Easy Setup and Operation Easy Setup and Operation

2 Connections

• The AVR-3806 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 72).

• 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

). 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

• 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.

• 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.

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.

Connecting the speaker cables

1. Loosen by turning

counterclockwise.

Either tightly twist or

terminate the core wires.

2. Insert the cable.

3. Tighten by turning

clockwise.

Connecting banana plugs

Turn clockwise to

tighten, then insert

the banana plug.
