Setting Bass and Treble Controls on
Your Receiver or Amplifier
Nonnally 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 BP7002/ BP7004/BP7006,
keeping in mind that even a little tum 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.
Powering Up the Active Subwoofer Section
Your BP7002/BP7004/BP7006s contain a built-in, active powered subwoofer
section as well as an electronic crossover and so each BP7002/BP7004/BP7006
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 BP7002/BP7004/BP7006
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.
Please note that if you hear a pop from the speaker when the amp powers up, this
is nonnal. 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 tum off. In some instances, because
of RF presence in your area, the red LEDs may not tum off. However, this is
nothing to be concerned about as the amplifiers draw almost no power when they
are idling.
To prevent accidental damage to the subwoofers built into your BP7002/
BP7004IBP7006s from overdriving the system, the subwoofers feature an
internal 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.
Setting Your Speakers' Low-Frequency
Level Control .
Your BP7002/BP7004/BP7006s 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
perfonnance benefit of this innovative product). We suggest beginning with the
level control set at approximately 12
0'
clock.
