Switching the speaker system
If you selected
2nd Zone
in
Surround back speaker setting
on page 35, three speaker system settings are possible
using the
SPEAKERS
button. If you selected
Normal (SB)
or
Front Bi-Amp
, the button will simply switch your main
speaker system on or off. The options below are for the
2nd Zone
setting only.
1
•
Use the SPEAKERS button on the front panel to
select a speaker system setting.
As mentioned above, if you have selected
Normal (SB)
,
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).
Bi-amping your front speakers
Bi-amping is when you connect the high frequency driver
and low frequency driver of your speakers to different
amplifiers (in this case, to both front and surround back
terminals) 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 below.
This illustration below shows the connections for bi-
amping your front left speaker. Hook up your front right
speaker in the same way.
Since both front and surround back speaker terminals
output the same audio, it doesn’t matter which set (front
or surround back) is powering which part (
High
or
Low
)
of the speaker.
• 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 35 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.
Note
1 • The subwoofer output depends on the settings you made in
Manual speaker setup
on page 42. 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 35 output from the surround back pre-out terminals may change.
• All speaker systems (except
2nd Zone
connections) are switched off when headphones are connected.
