The CVSUB50 subwoofer
is equipped with only one
input – a dedicated low-
frequency effects (LFE) input.
Since the LFE channel is by
definition limited to only the
lowest portion of the fre-
quency spectrum, it is cru-
cial that your receiver’s out-
put be compatible. The
CVSUB50 should only be
used with receivers or
processors that have digital
surround decoders, such as
Dolby* Digital or DTS.
® Do
not use the CVSUB50 with
components that output a
full-range signal through the
subwoofer output or with
components that only have
a line-level (preamp) output,
unless an outboard low-pass
crossover is used to filter the
signal.
Use the line-level input jack
marked “LFE” for the low-
frequency effects channel.
Connect this jack to the LFE
(subwoofer) output on your
receiver or processor.
Connect each speaker to
the corresponding speaker
terminals on your receiver
or amplifier.
Make sure that you have
configured your surround
sound processor for “Sub-
woofer On.” Also configure
your receiver for 5.1-, 6.1-
or 7.1-channel operation, as
appropriate. The front left,
front right, center and rear
speakers should all be set
to “Small.” If your receiver
allows you to set the cross-
over frequency between
the subwoofer and the main
speakers, select 90Hz or the
setting that is the closest
frequency below it (80Hz if
available).
