Connecting
the
Speaker Cables
Protection circuit
Carefully check the left (L)
and
right
(R)
channels and +
(red)
and -
(black) polarities
on
the speakers being connected to the AVR-1909,
and
be
sure to interconnect the channels and polarities correctly.
3
Insert the speaker cable's core wire to
the hilt into the speaker terminal.
4
Turn the speaker terminal clockwise to
tighten it.
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withdrawn, please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 O/ohmsL 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-1909
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 acti-
vated, due
to
thinking that the AVR-1909
has
failed, please contact
DENON Service center after switching off.

• Use speakers with
an
impedance of 6 to
16
O/ohms. When using
front A
and
B speakers simultaneously, use speakers with
an
impedance of
12
to
16
O/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
(&
"Protection circuit").
• Never touch the speaker terminals while the power supply
is
connected. Doing so could result
in
electric shock.
