LOUDSPEAKER SIZE SELECTION
When choosing loudspeaker sizes it is impor-
tant to take into consideration the low frequency
energy and demands of the home cinema sys-
tem. Generally loudspeakers using a single 8
inch or smaller low frequency driver need to be
specified as SMALL for home theater use with a
crossover of 80 Hz. Further details of this
requirement can be found on the Dolby Labs
web site.
STANDARD SUBWOOFER CONNECTION
When you choose Small for the Front Left and
Right speakers then the subwoofer will be
required for the system and the PRePro will not
allow the Subwoofer OFF selection, requiring
you to attach a Subwoofer into the system. The
default crossover point will be 80 Hz. If you
wish to use a different crossover frequency or
want to use an external crossover for the sub-
woofer this can be accomplished by chang-
ing the Crossover setting as indicated under
the Speaker Size menu. If you are using an
external crossover for the subwoofer then
select NONE for the Crossover frequency.
ENHANCED BASS SUBWOOFER
CONNECTION
If you have very large Front Left and Right
loudspeakers and wish to send the LFE infor-
mation to them as well as a subwoofer then
select the LARGE setting for the Front speak-
ers and Subwoofer OFF. The subwoofer can
then be connected either to one or both of
the front outputs of the PRePro or to the Amp
output(s) for the front speakers. In either case
the subwoofer crossover will need to be used
to connect in this manner. Please refer to the
subwoofer manual or dealer/installer for
details in connecting your specific subwoofer.
