Connecting additional amplifiers
This receiver has more than enough power for any home
use, but it’s possible to add additional amplifiers to every
channel of your system using the pre-outs. Make the
connections shown below to add amplifiers to power
your speakers.
• Before making or changing the connections, switch
off the power and disconnect the power cord from the
AC outlet.
• You can use the additional amplifier on the surround
back channel pre-outs for a single speaker as well. In
this case plug the amplifier into the left (L (Single))
terminal only.
• The sound from the surround back terminals will
depend on how you have configured the Surround
back speaker setting on page 35.
• To hear sound only from the pre-outs, switch the
speaker system to OFF, or simply disconnect any
speakers that are connected directly to the receiver.
• If you’re not using a subwoofer, change the front
speaker setting (see Speaker Setting on page 40) to
LARGE.
MULTI-ZONE listening
This receiver can power two independent systems in
separate rooms after you have made the proper MULTI-
ZONE connections.
1
Different sources can be playing in
both zones at the same time or, depending on your
needs, the same source can also be used. The main and
sub zones have independent power (the main zone power
can be off while the sub zone is on) and the sub zone can
be controlled by the front panel controls. However, you
may need to specify the volume setting in Multi Zone
Setup on page 58.
Making MULTI-ZONE connections
It is possible to make these connections if you have a
separate TV and speakers for your sub zone. You will also
need a separate amplifier if you are not using the
SurrBack System setup (see below). There are two
MULTI-ZONE setups possible with this system:
Basic MULTI-ZONE setup
• Connect a separate amplifier to the MULTI-ZONE
& SOURCE jacks and a TV monitor to the MULTI-
ZONE & SOURCE MONITOR OUT jacks, both on the
rear of this receiver.
You should have a pair of speakers attached to the sub
zone amplifier as shown in the illustration below.
