System Connections
• Be sure to connect speakers firmly and correctly according to the channel (left and right) and the polarity (+ and
−). If the connections are incorrect, no sound will be heard from the speakers, and if the polarity of the speaker
connection is incorrect, the sound will be unnatural and lack bass.
• When using only one surround back speaker, you should connect it to SURROUND BACK LEFT channel.
• When listening in Dolby Pro Logic IIz mode, connect the front height speakers.
• For installing the speakers, see "Speaker placement" on page 23.
• For ROOM 2 playback, connect the ROOM 2 speakers. For details, see "Connecting ROOM 2 & ROOM 3
OUTs" on page 24.
• After installing the speakers, first adjust the speaker settings according to your environment and speaker
layout. For details, see "Setting the Speaker/Room EQ Setup" on page 57.
• Depending on how to use the speakers, you should assign the power amplifier correctly. For details, see "AMP
Assign" of "Setting the System Setup" on page 56.
