Speaker System B Setup
Bi-amping the front speakers
For bi-amp playback you can connect both the A and B speaker terminals to your front speakers. To do this
your speakers must be bi-wireable (that is they must have separate terminals for the high and low
frequencies).
Bi-amping delivers more power to the front speakers, but disables the surround back speakers, so you will
be limited to 5.1 channel playback.
Bi-wiring your speakers
1
Connect your speakers as
shown.
Since both Front A and B speaker terminals
output the same audio, it doesnt matter which
set (A or B) is powering which part (HI or LOW)
of the speaker.
2
Select BI-AMP(5.1). If you need
more information on how to do
this see page 37, step 3.
The surround back channel amplifier is now
used to power the B set of speaker terminals
and the A+B (SP3AB) speaker setting is
automatically selected. The speaker setting in
this case can only be A+B or OFF.
Caution!
Do not allow any speaker wire from any
terminal to touch a wire from a different
terminal.
Caution!
Most speakers with both Hi and Low
terminals have two metal plates that
connect the Hi 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.
In order 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 sets of speaker cords to each speaker
terminal on the receiver. The easiest way to do this is to connect one wire in
the normal way, and use a banana plug for the other one. Make sure you use
a parallel (not series) connection when doing so. Don't connect different speak-
ers from the same terminal in this way.
When using this kind of connection, select NORMAL SURROUND.
Stereo playback in another room
Connect a pair of speakers to the B speaker terminals to listen to stereo playback in another room (kitchen,
bedroom, etc.). Select NORMAL SURROUND and choose the speaker system setup that you want.
See the next page for more details on these speaker system settings.
Please use speakers with a nominal impedance rated 6-16.
