Easy Setup and Operation
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
sense of direction of the stereo being impaired.
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.
Connecting the speaker cables
1. Loosen by turning
counterclockwise.
2. Insert the cable.
3. Tighten by turning clockwise.
Either tightly twist or terminate the core wires.
Connecting banana plugs
Turn clockwise to tighten, then
insert the banana plug.
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.
¢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.
