Definitive Technology 3000 owner manual Powering Up the Active Subwoofer Section

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 C/L/R 3000, keep- ing 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 recom- mend 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 C/L/R 3000(s) contains a built-in, active powered subwoofer section as well as an electronic crossover; so each C/L/R 3000 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 C/L/R 3000 has a special circuit which automati- cally turns the powered subwoofer section on when a signal is fed to the loud- speaker 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.

Setting Your C/L/R 3000’s Low-Frequency Level Control

Your C/L/R 3000 has a level control for the electronic crossover 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 pref- erences. Please note that there are no controls to vary the crossover points or

phase because these have been factory set to provide perfect blending (a major performance benefit of this innovative product). When using the speaker wire input, we suggest beginning with the level control set at approximately 10 o’clock. However, when using the “Full Range Low-Level In” with the jumpers

removed between “Mid” and “Low,” the level control starting point position may vary and you must experiment for optimum setting. Set the level control so that the sound is most pleasing to you. In general, when used as a center channel, the C/L/R 3000 subwoofer should not be turned up excessively high to add more “room shaking level bass” but should be kept in proper balance with the upper bass/midrange drivers in order to achieve properly balanced high- impact full-range center channel presentation.
