Switching the speaker system

If you selected Speaker B in Surround back speaker
setting on page 56, three speaker system settings are
possible using SPEAKERS. If you selected Normal or
Front Bi-Amp, the button will simply switch your main
speaker system on or off. The options below are for the
1
Speaker B setting only.
• Use SPEAKERS on the front panel to select a
speaker system setting.
As mentioned above, if you have selected Normal, the
button will simply switch your main speaker system (A)
on or off.

Press repeatedly to choose a speaker system option:
• SPA – Sound is output from speaker system A and
the same signal is output from the pre-out terminals.
• SPB – Sound is output from the two speakers
connected to speaker system B. Multichannel
sources will not be heard. The same signal is output
from the surround back channel pre-out terminals.
• SPAB – Sound is output from speaker system A (up
to 5 channels, depending on the source), the two
speakers in speaker system B, and the subwoofer.
The sound from speaker system B will be the same as
the sound from speaker system A (multichannel
sources will be downmixed to 2 channels).
• SP (off) – No sound is output from the speakers. The
same sound is output from the pre-out terminals
(including from your subwoofer, if connected) as
when selecting speaker system A (above).
Note
1 • The subwoofer output depends on the settings you made in Manual speaker setup on page 55. However, if SPB is selected above, no sound
is heard from the subwoofer (the LFE channel is not downmixed).
• Depending on the settings in Surround back speaker setting on page 56 output from the surround back pre-out terminals may change.
• All speaker systems (except Speaker B connections) are switched off when headphones are connected.

Bi-amping your speakers

Bi-amping is when you connect the high frequency driver
and low frequency driver of your speakers to different
amplifiers for better crossover performance. Your
speakers must be bi-ampable to do this (having separate
terminals for high and low) and the sound improvement
will depend on the kind of speakers you're using.
1 Connect your speakers as shown next page.
This illustration below shows the connections for bi-
amping your front left speaker. Hook up your bi-amp
compatible speakers for other channels in the same way.

• Make sure that the + / – connections are properly
inserted.
2 Select the 'Front Bi-Amp' setting from the 'Surr
Back System' menu.
See Surround back speaker setting on page 56 to specify
how you're using the surround back speaker terminals.
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.
