Bridging the Front Speakers
The
FRONT L/R
and
SURR BACK/ZONE 3 L/R
terminal
posts can be used with front speakers and surround back speak-
ers respectively, or bridged together to provide almost double
the output power for the front speakers.
• When bridging is used, surround back speakers cannot be
used.
• For bridging, the positive (+)
FRONT L/R
and
SURR
BACK/ZONE 3 L/R
terminal posts are used, but the negative
(–)
FRONT L/R
and
SURR BACK/ZONE 3 L/R
terminals
are not.
• Once you’ve completed the bridging connections shown below
and turned on the AV receiver, you must set the
“
Speakers Type(Front)
” setting to “
BTL
” to enable bridging
(
➔
54
).
Note
• Use only front speakers with an impedance of 8 ohms or higher for bridging. Failure to do so may seriously damage the AV
receiver.
• When using bridging, make sure that your front speakers can handle the additional power.
Connecting the Passive Subwoofers
The
FRONT WIDE/ZONE 2 L/R
terminal posts can be
used with front wide speakers or passive subwoofers.
• Once you’ve connected the passive subwoofers and
turned on the AV receiver, you must set the “
Passive
Subwoofer
” setting to “
Use
” (
➔
54
).
• When the passive subwoofers are used, the Powered
Zone 2/4 cannot be used.
• If you use one passive subwoofer, connect it to the
SUBWOOFER1
terminals.
Connecting a Power Amplifier
If you want to use a more powerful power amplifier and use the AV receiver as a preamp, connect it to the
PRE OUT
jacks, and connect all speakers to the power amplifier.
