Connections
Be sure to connect the left channel (L), right channel (R), “+” (red) and “–” (black) properly. If the connections are faulty,
this unit cannot reproduce the input sources accurately.
• A speaker cord is actually a pair of insulated cables running side by side. Cables are colored or shaped differently, perhaps with a
stripe, groove or ridge. Connect the striped (grooved, etc.) cable to the “+” (red) terminals of this unit and your speaker. Connect the
plain cable to the “–” (black) terminals.
• You can connect both surround back and presence speakers to this unit, however they do not output sound simultaneously. This unit
automatically switches the presence speakers and surround back speakers depending on the input sources and the selected sound field
programs.
■ 7.1-channel speaker connection
Connecting speakers
Caution
• Before connecting the speakers, make sure that this unit is turned off (page 26).
• Do not let the bare speaker wires touch each other or do not let them touch any metal part of this unit. This could
damage this unit and/or speakers.
• Use magnetically shielded speakers. If this type of speaker still creates interference with the monitor, place the
speakers away from the monitor.
• If you are to use 6-ohm speakers, be sure to set “SPEAKER IMP.” to “6
Ω MIN” before using this unit (page 26).
You can also use 4-ohm speakers as the front speakers (page 121).
