ProtectiOn
circqit
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off, after the power supply cord is withdrawn,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 th'an that
specified (eg, 4 O!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-1709 has cooled down,
and
the surrounding ventilation
is
good.
Even
if there
are
no
problems with the surround-
ing ventilation and connections,
in
the event of
the protection circuit becoming activated, due to
thinking that the
AVR-1709
has
failed, please con-
tact

Turn the speaker terminal
counterclockwise to loosen
it.
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-1709,
and
be sure to
interconnect the channels
and
polarities correctly.
Tighten the speaker terminal firmly before
inserting the
banana
plug.
4
Turn the speaker terminal
clockwise
to
tighten it.
1
Peel offabout 0.03 ftil0 nun
of
sheathing from the tip of
the speaker cable, then either
twist the core wire tightly or
terminate it.
3
Insert the speaker cable's
core wire
to
the hilt into the
.speaker terminal.
When using a banana plug
-mu·
• 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
((F"Protection
circuit").
• Never touch the speaker terminals while the
power supply
is
connected. Doing
so
could result
in
electric shock.

For surround back speakers:
•
By
default, the AVR-1709's
"Amp
Assign" setting
is
set to "ZONE2".
To
use
as
the surround back
speaker for the main zone, change the "Amp Assign" setting
(~page
28).
• When using just one surround back speaker, connect it to the left channel
(SBL).
For ZONE2 speakers:
•
For
multi-zone connection
and
operation, see "Amp Assign / Multi-zone Connections
and
Operations"
