Caution
• Most speakers with both High and Low terminals
have two metal plates that connect the High to the
Low terminals. These must be removed when you are
bi-amping the speakers or you could severely
damage the amplifier. See your speaker manual for
more information.
• If your speakers have a removable crossover network,
make sure you do not remove it for bi-amping. Doing
so may damage your speakers.
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).
• To bi-wire a speaker, connect two speaker cords to
the speaker terminal on the amplifier.
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 amplifier 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.
• The sound from the PREOUT SURROUND BACK and
PREOUT EXTRA terminals will depend on how you
configured the
Speaker output setting on page 43.
Pay attention to this when connecting another power
amplifier, etc.
• 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.
• 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 amplifier.
• If you’re not using a subwoofer, change the front
speaker setting (see Speaker Setting on page 52) to
large.
