NOTE

For surround back speakers :

• When using just one surround back speaker, connect it to the left channel (SBL).

For ZONE2 speakers :

• When outputting audio from the surround back speakers with ZONE2, set to “ZONE2” with “Manual

Setup” – “Option Setup” – “Amp Assign” from the menu. For multi-zone connection and operation, see

“Amp Assign / Multi-zone Connections and Operations” (vpage 60 ~ 62).

Connections

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-2309, and be sure to interconnect the channels and polarities correctly.

1Peel off about 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.

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 protec-

tion 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 If the power supply is turned off, after the power supply cord is withdrawn, please con-

ﬁrm 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-2309 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 pro-

tection circuit becoming activated, due to thinking that the AVR-2309 has failed, please contact DENON

Service center after switching off.
