Connecting the Speaker Cables
Carefully check the left (L) and right (R) channels and + (red) and
– (black) polarities on the speakers being connected to the AVR-390,
and be sure to interconnect the channels and polarities correctly.
1
Peel off the sheath from the tip
of the speaker cable, then firmly
twist the wires by hand so that they
do not stick out and cause short-
circuits.
2
Turn the speaker terminal counterclockwise
to loosen it.
3
Insert the speaker cable’s core wire to the
hilt into the speaker terminal.
4
Turn the speaker terminal clockwise to
tighten it.
NOTE
• Use speakers with an impedance of 6 to 16 Ω/ohms.
• Connect the speaker cables in such a way that they do not stick out
of the speaker terminals. The protection circuit may be activated if
the core wires touch the rear panel or if the + and – sides touch each
other (
v
“Protection circuit”).
• Never touch the speaker terminals while the power supply is
connected. Doing so could result in electric shock.
Protection circuit
If the core wires touch the rear panel and the screws etc., or the ±
sides touch each other, the protection circuit will be activated and
the power indicator will flash red at intervals of 0.5 secs.
If the protection circuit is activated, the speaker output is isolated,
and the power supply goes to the standby state. If the power
supply is turned off, after the power cord is withdrawn, please
confirm that speaker cable and input cable are connected.
Also, if replaying large sound levels by using a speaker having an
impedance less than that specified (eg, 4 Ω/ohms), the temperature
will rise, and the protection circuit might be activated. The power
supply will go into the standby state, and the power indicator will
flash red at 2 second intervals.
In this case, please switch off the power supply, and wait until the
AVR-390 has cooled down, and the surrounding ventilation is good.
Even if there are no problems with the surrounding ventilation
and connections, in the event of the protection circuit becoming
activated, due to thinking that the AVR-390 has failed, please
contact DENON Service center after switching off.
