If you have a Dolby Digital system, “tell” your bass management system
that you have “Large” left and right front speakers and “No” subwoofer.
The base management system will then send the LFE .1 channel signal into
the left and right channels, and it will be reproduced by the subwoofers in your
BP7000
SC/ BP7001SCs, giving you all the benefits of Dolby Digital and the
discrete LFE signal.
Usually if distortion is heard when the speakers are being driven
at loud levels, it is caused by driving (turning up) the amplifier too loud
and not driving the speakers with more power than they can handle.
Remember, most amplifiers put out their full-rated power well before the
volume control is turned all the way up! If your speakers distort when you
play them loud, turn down the amplifier or get a bigger one.
Using Your Speakers with Dolby Digital Systems
with and without the Separate LFE Input
There are many options for hooking up your BP7000SC/BP7001SCs to a Dolby
Digital and DTS 5.1 (6.1, 7.1) system. The basic hook-up of the speakers is the
same as described in the preceding sections of this manual (Diagrams 1-2). The
simplest way to use the speakers with Dolby Digital and DTS 5.1 (6.1, 7.1) would
then be to hook up the speakers according to any one of these diagrams (Diagrams
1-2) and then use the “bass management system” built into your receiver or decoder
to internally direct the LFE (.1 discrete bass) signal to the left and right channels
where it would be fed to the subwoofer contained in each BP7000
SC/BP7001SC
loudspeaker. This can be accomplished through your Dolby Digital and DTS 5.1
(6.1, 7.1) decoding bass management system by “telling the electronics” (usually by
using its on-screen display control feature) that you don’t have a subwoofer “No”
and that you have “Large” left and right front speakers. Since the LFE .1 sub signal
is then delivered to your subwoofers through the speaker wire, you will then get the
full benefit of it as well as the bass information from the left and right channel as the
advance circuitry within the speaker takes an infinitesimally small signal from the
speaker wire and uses it to drive the built-in subwoofer amplifiers. If you have a
Definitive center channel with a built-in powered subwoofer, you would normally
tell the bass management system that you have a “Large” center channel.
Otherwise, it would normally be set to “Small” center channel. However, in either
case, you should experiment to see what sounds best in your particular system.
Alternatively, you can use the LFE/Sub Out jack on your electronics to feed
the LFE input jacks on your BP7000
SC/BP7001SCs. Simply use a Y connection
coming out of the LFE output jack on your electronics to feed two line level cables,
one connected to the LFE input on the right speaker and the other one connected
to the LFE input on the left speaker. Use the bass management system on your
decoder to “tell” your electronics that you have large left and right main speakers
and subwoofer “Yes.”
When using the separate LFE inputs: If you have the speakers connected full
range with all jumpers in, leave all the jumpers in. You can also use the separate
LFE input in conjunction with bi-wiring the speakers as described on page 8.
