NOTE
For surround back speakers :
• Since “Amp Assign” of AVR-2809CI is set to “ZONE2” by default, audio is not output from the surround
back speakers. When using the surround back speakers with MAIN ZONE, change the “Amp Assign”
setting to “7.1ch” (vpage 32).
• When using just one surround back speaker, connect it to the left channel (SBL).
For ZONE2/ZONE3 speakers :
• When outputting audio from the surround back speakers with ZONE2 or ZONE3, set to “ZONE2” or
“ZONE3” 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 67,
68).
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-2809CI, 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.
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 8 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 If the power supply is turned off, after the power supply cord is withdrawn, please con-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-2809CI 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 activated, due to thinking that the AVR-2809CI has failed, please contact
DENON Service center after switching off.

When using a banana plug
Tighten the speaker terminal firmly before inserting the banana plug.
Connect when
using 7.1-
channel.
