Definitive Technology BP7001SC - Manual (Page 12)

Normally the level control of the left speaker will be set the same as the level
control of the right speaker. However, these controls can also be set differently
on the two speakers in order to allow you to vary the response of left and
right speakers separately to compensate for variations and asymmetrical
positioning of the left and right speakers in your room (i.e., when one is
closer to a side wall or corner, etc.) if this is how you must set them up. This is
a very unique and useful feature which allows you much greater flexibility in
loudspeaker placement, as well as the ability to optimize what could otherwise
be difficult placement situations.
VERY IMPORTANT: Setting Channel Balance
and Bass Management Systems
Dolby Digital and DTS 5.1 (6.1, 7.1) systems and decoders have a critical
channel balancing procedure for the left and right front speakers, center
channel, rears and subwoofer (if it is hooked up through the “LFE or Sub Out”
low-level connection) which must be followed if the system is to perform
properly. We have spoken with many system users with problems relating to
the overall sound of their system which could be clearly traced back to improper
system balance. In fact, many users never realize that there is a system balance
procedure to be followed.
Also note that Dolby Digital and DTS 5.1 (6.1, 7.1) systems and decoders
have bass management systems (systems which direct the bass to the various
channels) which vary from unit to unit. This bass management system must also
be properly adjusted. We have spoken with many system users with problems
relating to the overall sound of their system which could be clearly traced back to
improper bass management. In fact, many users never realize that there is a bass
management procedure to be followed.
If your BP7000
SC
/BP7001
SC
s are hooked up with speaker level wires and
no low-level LFE channel input, your receiver or decoder’s bass management
system should be set for “Large” left and right main speakers and “No”
subwoofer (even though you have subwoofers built into your BP7000
SC
/
BP7001
SC
s). This will properly channel the sub bass LFE information into
the left and right channels and then into your subwoofers built into your
BP7000
SC
/BP7001
SC
s. If you have a Definitive center channel with a built-in
powered subwoofer, set your decoder’s bass management center channel setting
to “Large” (although you should experiment with this to see what sounds best in
your specific system). If you are using large rear surround speakers with very
extended low frequency response such as a large Definitive floor-standing system
or one with a built-in powered subwoofer, set the rear channels of your decoder’s
bass management system to “Large.” If not, set them to “Small.”
Setting Low-Frequency Balance When Using Separate LFE Input
We suggest that when you are using a separate LFE input, you set the bass
level on your BP7000 SC /BP7001 SC s to sound balanced when listening to music
in stereo and use the .1 channel or bass level control in your Dolby Digital channel
balancing procedure on your decoder to raise or lower the bass level for movie
sound effects as you require.
