SPEAKER CONNECTIONS
1) If your receiver/amplifier has no
subwoofer outputs or preamp outputs
for the left, center and right channels.
See Figure 1.
2) If your receiver/amplifier has
subwoofer outputs or preamp output
jacks for the left, center and right
channels, or left and right only. See
Figure 2.
If your receiver/amplifier has a single
(mono) subwoofer output or LFE
output, 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”-connector into the
receiver/amplifier, and connect each
of the 2 female connectors to an
RCA-type interconnect cable. Then
connect the 2 interconnect cables to
the Left and Right line-level inputs on
the PSW-D115.
