NOTE
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 (vpage 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”
(vpage 51 ~ 53).

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.
1
Peel 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.
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.
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
Ω/ohms. When using front A and B speakers
simultaneously, use speakers with an impedance
of 12 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off, after the power supply cord is withdrawn,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 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-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 DENON Service center after switching off.
