Connecting Passive Subwoofers
The FRONT HIGH/ZONE 3 L/R terminals can be used
with front high speakers, Zone 3 speakers, or passive
subwoofers.
The level and distance can be set for SUBWOOFER1 and
SUBWOOFER2 respectively.
Once you've connected the passive subwoofers and turned
on the AV receiver, you need to enable the "Passive
Subwoofer" setting (➔ page 63).
If you use one passive subwoofer, connect it to the
SUBWOOFER1 terminals.

Bi-amping the Front Speakers
Important:
• When making the bi-amping connections, be sure to remove
the jumper bars that link the speakers' tweeter (high) and
woofer (low) terminals.
• Bi-amping can be used only with speakers that support bi-
amping. Refer to your speaker manual.
Bi-amping provides improved bass and treble performance.
When bi-amping is used, the AV receiver is able to drive
up to a 7.2 speaker system in the main room.
Once you've completed the bi-amping connections as
Subwoofer 1
shown and turned on the AV receiver, you must set the
speaker setting to enable bi-amping (➔ page 63).

Using Speakers Without Crossover Network
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 "Speakers 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.
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 7.2 speaker system in the main room.
You must enable "Digital Crossover" in "Speakers
Type(Front)" (➔ page 63) and make the settings of
"Digital Processing Crossover Network" (➔ page 67).
Note
• You need to make the setting before connecting the speakers.
