Determining the speakers’ application
This unit permits you to build various surround systems, in accordance with the number of speakers you have.
!
Be sure to connect speakers to the front left and right channels (
L
and
R
).
!
It is also possible to only connect one of the surround back speakers (
SB
) or neither.
!
If you have two subwoofers, the second subwoofer can be connected to the
SUBWOOFER 2
terminal.
Connecting two subwoofers increases the bass sound to achieve more powerful sound reproduction. In this
case, the same sound is output from the two subwoofers.
Important
!
The
Speaker System
setting must be made if you use any of the connections shown below other than [A] (see
Speaker system setting
on
page 93
).
!
The speakers from which sound is output can be switched according to the speaker layout/usage pattern
(sound is not necessarily output from all connected speakers). Use the
OUT P.
button to switch the speakers
from which sound is output. For details, see
Switching the speaker terminals
