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 2500, 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 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 2500(s) contains a built-in, active powered subwoofer section as
well as an electronic crossover and so each
C/L/R 2500
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 2500 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 of

Setting Your
C/L/R 2500
’s Low-Frequency Level
Control
Your
C/L/R 2500
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 1
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 2500 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.
