If you are still having problems, you could try the following: The ROOM COMPENSATION switch
allows
you to lower the bass range, depending on the speaker position. Ex-factory, the switch is set to a neutral
position. If you've set up the TRUTH close to the wall or in a corner, try reducing the low-frequency level in
steps of 2 dB. Since every room and speaker setup are unique in their acoustic properties, we cannot
provide more specific information here. The same applies to the HIGH FREQUENCY switch
, which
determines the tweeter level (b2 dB and -4 dB). Here too, the best setting depends on the room
acoustics. If you have an additional subwoofer installed, you should match the TRUTH's lower cutoff frequency
to that of the subwoofer, using the LOW FREQUENCY switch
. Unless the appropriate frequency is given
in the subwoofer documentation, it must be determined by ear.
As a general rule, you should set up and adjust the TRUTH with great care. Above all, you should take your
time: unlike hi-fi speakers, the B2031 is tuned to produce a neutral sound, which can be confusing when you
are working for the first time with such a high-quality speaker. Don't try to adjust the TRUTH with its rear-wall
switches to produce a "bombastic" sound that impresses you or other listeners. To get a feeling for the
TRUTH's sound, you should listen to as many records as possible that were produced in other studios. We
also recommend that you listen to your own recordings over as many other systems as possible, for example,
your car system. If you find that your mixes are somewhat "dull" in their overall sound, the reason might be
too much treble power from your TRUTH. On the other hand, if you set the bass level to high, you will find that
your mixes lack bass power. Tuning a speaker can take several days' time, so once again: take your time!
It might be necessary to insert an equalizer between console and speaker, in particular, if you prefer extreme
setups or sound images. The BEHRINGER ULTRA-CURVE PRO DSP8024 has proven its usefulness in
practice, as it is not only a simple equalizer but also includes analyzer circuitry. You can use our measuring
microphone ECM8000 to automatically adapt the TRUTH to your room or modify its frequency response.
