Connecting a Power Amplifier
If you want to use a more powerful power amplifier, you
can use the AV receiver as a preamp. Connect all speaker
outputs to the power amplifier. See the manuals supplied
with your amplifier for details.
SB···Surround Back, FH···Front High, FW···Front Wide
Note
*1 Specify “None” for any channel that you don’t want to output
(
➔ page 60 ).
*2 When connecting to the SB/FH/FW EXT AMP jacks, you
must set the “Preout to External Amplifier” setting
(
➔ page 59 ).
Using Speakers Without Crossover Network
Connecting speakers without crossover network provide a
fine, three-dimensional sound field that extends bass and
treble performance to the fullest extent. When speakers
without crossover network are used, the AV receiver is
able to drive up to a 5.1 speaker system in the main room.
You must enable “Digital Crossover” in “Speaker Type
(Front)” (
➔ page 59 ) and make the settings of “Digital
Processing Crossover Network” ( ➔ page 63 ).
Note
• You need to make the setting before connecting the speakers.

Important:
• Speakers without crossover network are speakers with no
built-in crossover network.
• With speakers without crossover network, be careful NOT to
connect tweeters and woofers the wrong way around, as this
may damage your speakers.
• With speakers without crossover network, be careful not to set
“Speaker Type (Front)” to “Bi-Amp” as this may damage
your speakers. Make sure that this setting is set to “Digital
Crossover”.
• Confirm that your speakers are without crossover network by
referring to your speaker manual.
