the wall opposite the speakers might be a good idea if the room is
too reective. The next chapter describes how to adapt the TRUTH
to the room acoustics, once it has been set up properly.
Adapting the TRUTH to the room acoustics3.4
This chapter describes how you can use the switches on the rear
of the B2030A/B2031A to adapt the speaker to the acoustics of
your control room. However, you should try to improve a poten-
tially impaired sound by optimizing the loudspeaker placement
beforehand.

If you are still having problems, you could try the following: The
ROOM COMPENSATION switch {9} 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 specic information
here. The same applies to the HIGH FREQUENCY switch (10),
which determines the tweeter level (between +2 dB and -4 dB).
Here too, the best setting depends on the room acoustics. If you
have an additional subwoofer installed, you can attenuate the
TRUTH’s lower cutoff frequency using the LOW FREQUENCY
switch {8}. This can be necessary when adapting the TRUTH
to your subwoofer. Trust your own aural instinct, but don’t forget:
Listening at high volume levels over long periods leads to listening
fatigue and thus reduces your ability to judge the sound. Con-
sequently, we recommend regular pauses to keep your hearing
"healthy".
As a general rule, you should set up and adjust the TRUTH with
great care. Above all, you should take your time: unlike hi- speak-
ers, the B2030A/B2031A is tuned to produce a neutral sound,
which can be confusing when you are working for the rst time with
such a high-quality speaker. Don’t try to adjust the TRUTH with its
rear panel 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 nd that your mixes are somewhat "dull" in
their overall sound, the reason might be too much treble from your
TRUTH. On the other hand, if you set the bass level too high, you
will nd 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 ULTRACURVE PRO DEQ2496 has
proven its usefulness in practice, as it is not only a simple equalizer
but also features a real-time analyzer. You can use our measuring
microphone ECM8000 to automatically adapt the TRUTH to your
room or modify its frequency response.

The BEHRINGER TRUTH features one balanced XLR and one bal-
anced 1/4" TRS input. If connecting to other equipment is possible
using balanced inputs, always make such connections because
they offer maximal compensation of disturbing signals.
