Definitive Technology BP7006 Setting Bass and Treble Controls on, Your Receiver or Amplifier

Setting Bass and Treble Controls on

Your Receiver or Amplifier

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 BP7002/ BP7004/BP7006, 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.

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 normal. 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.

To prevent accidental damage to the subwoofers built into your BP7002/ BP7004/BP7006s 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 performance benefit of this innovative product). We suggest beginning with the level control set at approximately 12 o’clock.
