TRUTH B2031A/B2030A User Manual

Fig. 3.2: Correct speaker setup

This effect can be reduced by turning the speakers towards the listener. To make 

reflections from ceiling or floor less likely, the tweeters should be on the same 

height as your ears. Please note that the TRUTH should be operated vertically. 

Where this is impossible, place it horizontally as shown in figure 3.3, to allow for 

an improved stereo image.

Not only the physical location of speakers but also the acoustic characteristics 

of the room have a substantial effect on the way your TRUTH sounds. Make sure 

that the room neither sounds too hall-like nor too dull-basically, neither like a 

bathroom nor totally without an echo. You can alter the room acoustics easily by 

installing or removing carpets, curtains or furniture. Fabric covering on the wall 

opposite the speakers might be a good idea if the room is too reflective. The next 

chapter describes how to adapt the TRUTH to the room acoustics, once it has been 

set up properly.

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 potentially 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 specific 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. 

Consequently, 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-fi speakers, the B2030A/B2031A 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 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 find 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 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 

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.
