When using a banana plug Tighten the speaker terminal firmly before inserting the banana plug. NOTE b L : Left R : Right (L) (R) w qw q (L) (R) w qw q • 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"). Connect when • Never touch the speaker terminals while the power supply is connected. Doing so could result in electric using 7.1- shock. channel. Protection circuit Surround speakers Surround back speakers NOTE For surround back speakers : • S ince "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). • W hen using just one surround back speaker, connect it to the left channel (SBL). For ZONE2/ZONE3 speakers : • W hen 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). 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 If the power supply is turned off, after the power supply cord is withdrawn, please confirm that speaker cable and input cable are connected.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-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. 10
