3) If your receiver/amplifier

has a single (mono) sub-
woofer output or LFE out-
put, you may connect the
output to either the Left
or Right line-level input
on the subwoofer.
However, to maximize the
subwoofer’s performance,
we recommend that you

use a “Y”-connector (not
included). Plug the single
male end of the “Y”-con-
nector into the subwoofer
output on the receiver/
amplifier, and connect
each of the 2 female con-
nectors to an RCA-type
interconnect cable. Then
connect the 2 intercon-

nect cables to the Left
and Right line-level
inputs on the PSW-D112.

Note: If your receiver/proces-
sor contains Dolby* Digital or
DTS® surround processing
technology, then set the 
“Low-Pass” control on the
180Hz position.

has subwoofer outputs 
or preamp output jacks
