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-2309CI,
and be sure to interconnect the channels and polarities correctly.
1Peel off about 0.03 ft/10 mm of sheathing
from the tip of the speaker cable, then
either twist the core wire tightly or
terminate it.
2Turn the speaker terminal
counterclockwise to loosen it.
3Insert the speaker cable’s core wire to
the hilt into the speaker terminal.
4Turn the speaker terminal clockwise to
tighten it.
When using a banana plug
Tighten the speaker terminal firmly before
inserting the banana plug.
NOTE
• Use speakers with an impedance of 6 to 16 /ohms. When using
front A and B speakers simultaneously, use speakers with an
impedance of 12 to 16 /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 sup-
ply is turned off, after the power supply cord is withdrawn, please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 /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-2309CI 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 activat-
ed, due to thinking that the AVR-2309CI has failed, please contact
DENON Service center after switching off.
