Bi-wiring your speakers

The reasons for bi-wiring are basically the same as bi-
amping, but additionally, interference effects within the
wire could be reduced, producing better sound. Again, to
do this your speakers must be bi-wireable (that is they
must have separate terminals for the high and low
frequencies). When bi-wiring, make sure you've selected
Normal (SB) or 2nd Zone in Surround back speaker
setting on page 35.
• To bi-wire a speaker, connect two speaker cords to
the speaker terminal on the receiver.
Using a banana plug for the second connection is
recommended.
Caution
• Make sure you use a parallel (not series, which are
fairly uncommon) connection when bi-wiring your
speakers.
• Don't connect different speakers from the same
terminal in this way.

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 42) to
LARGE.
