Definitive Technology BP7001SC - Manual (Page 11)

Normally we recommend that you set the “Bass” and “Treble” controls
on flat or 0 dB. This will give you the most linear and natural sound. If you want
more bass, raise the subwoofer’s “Level” control on your BP7000
SC / BP7001 SC ,
keeping in mind that even a little turn of the knob can make a big difference in the
sound. Also, if your amplifier or receiver has a graphic equalizer, we recommend
that you leave it flat. The reason for this is that we have spoken with many
consumers about what they thought were improperly sounding speakers when,
in fact the problem was misadjusted tone controls. When in doubt, leave them flat;
this almost always sounds the best.
Your BP7000 SC /BP7001 SC s contain a built-in, active powered subwoofer
section as well as an electronic crossover and so each BP7000 SC /BP7001 SC must
be plugged into an electrical socket of the appropriate voltage (as indicated on
the back of your unit) using the plug on the end of the black cord attached to the
electronics module on the back of the loudspeaker. The BP7000
SC /BP7001 SC has
a special circuit which automatically turns the powered subwoofer section on
when a signal is fed to the loudspeaker and does not require an on-off switch.
The red LED on the back panel will light up when a signal is sensed and the
amplifier turns on. Please note that after the cessation of a signal, it may take up
to an hour for the amplifier to actually turn off. In some instances, because of RF
presence in your area, the red LEDs may not turn off. However, this is nothing to
be concerned about as the amplifiers draw almost no power when they are idling.
Your BP7000
SC /BP7001 SC s have a level control which allows you to perfectly
tune the output level of the powered low frequency subwoofer section to match
your room as well as to fulfill your own personal listening preferences. Please note
that there are no controls to vary the crossover points or phase because these have
been factory calibrated and set to provide perfect blending (a major performance
benefit of this innovative product). We suggest beginning with the level control
set at approximately 12 o’clock.

overload protection circuit, which will turn the subwoofers off or down when
overdriven or overheated and will then resume normal operation after a
few minutes.
