For surround back speakers :

•Since “Amp Assign” of AVR-789 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 31).

•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 65 ~ 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-789, and be sure to interconnect the channels and polarities correctly.

1Peel 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.

2Turn the speaker terminal counterclockwise to loosen it.

3Insert the speaker cable’s core wire to the hilt into the speaker terminal.

4Turn 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.
