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). 

The following steps use the front panel controls to adjust 
the sub zone volume and select sources. See MULTI-

is heard from the subwoofer (the LFE channel is not downmixed).
• Depending on the settings in Surround back speaker setting on page 91 output from the surround back pre-out terminals may change.
• All speaker systems (except Speaker B connections) are switched off when headphones are connected.

zone. Please be careful not to change stations when recording a radio broadcast.
