them ideal for studio use. The task of designing our new B2030P  
and B2031P certainly meant a great deal of responsibility, which  
we assumed by focusing on you, the discerning user and  
musician. Meeting your expectations also meant a lot of work  
and night shifts. But it was fun, too. Developing a product usually  
brings a lot of people together, and what a great feeling it is  
when all who participated in such a project can be proud of  
what they’ve achieved.  
1. INTRODUCTION  
Congratulations! With our new BEHRINGER TRUTH you have  
purchased one of the best high-resolution passive studio  
monitors available. It is a tool that reproduces your program  
material with highest fidelity and balance, positioning sound  
sources accurately on the stereo basis.  
It is our philosophy to share our enjoyment with you, because  
you are the most important member of the BEHRINGER team.  
With your highly competent suggestions for new products you’ve  
made a significant contribution to shaping our company and making  
it successful. In return, we guarantee you uncompromising quality  
as well as excellent technical and audio properties at an extremely  
reasonable price. All of this will enable you to give free rein to  
your creativity without being hampered by budget constraints.  
The TRUTH speakers stand out thanks to their toughness and  
extremely neutral and authentic sound rendition. In the bass  
range, they operate with polypropylene membranes and smooth  
suspension. Their scope is broadened downward by using a  
special bass reflex system. In the upper frequency range, a  
specially developed ferrofluid-cooled aluminum tweeter provides  
for subtle signal reproduction. The TRUTH is magnetically shielded,  
so you can use it near computer monitors or TV sets. The audio  
signal is separated using a low-distortion crossover that creates  
a phase-optimized frequency separation.  
We are often asked how we manage to produce such high-  
quality devices at such unbelievably low prices. The answer is  
quite simple: it’s you, our customers! Many satisfied customers  
mean large sales volumes enabling us to get better purchasing  
terms for components, etc. Isn’t it only fair to pass this benefit on  
to you? Because we know that your success is our success  
too!  
We recommend that you experiment with your TRUTH away  
from the pressures of a recording session, in order to get a feel  
for it. It will be a good idea to listen to your favorite CD’s over the  
TRUTH, so that you can get an impression of the neutral sound  
this speaker produces—which might be somewhat unusual at  
first!  
I would like to thank all of you who have made the TRUTHs  
possible. You have all made your own personal contributions,  
from the developers to the many other employees at this company,  
and to you, the BEHRINGER user.

The following user’s manual is intended to  
familiarize you with the unit’s control elements,  
so that you can master all the functions. After having  
thoroughly read the user’s manual, store it at a safe  
place for future reference.  
My friends, it’s been worth the effort!  
Thank you very much,  
Uli Behringer  
ATTENTION!

The TRUTH is capable of producing extreme  
volumes. Please bear in mind, that high sound  
pressures do not only temporarily damage your  
sense of hearing, but can also cause permanent  
damage. Be careful to select a suitable volume.

1. INTRODUCTION  
 
TRUTH B2030P/B2031P  
This is the terminal clamp for the minus cord of your speaker  
cable.  
1.1 Before you get started  
1.1.1 Shipment  
This is the terminal clamp for the plus cord of your speaker  
cable.  
The B2030P/B2031P were carefully packed at the factory to  
assure secure transport. Should the condition of the cardboard  
box suggest that damage may have taken place, please inspect  
the unit immediately and look for physical indications of damage.  
The connection terminal of your TRUTH is recessed. This way,  
you can place it in the vicinity of walls.  
+
Always power down your amp before connecting it  
to the TRUTH.  
+
Damaged units should NEVER be sent directly to us.  
Please inform the dealer from whom you acquired  
the unit immediately as well as the transportation  
company from which you took delivery of the unit.  
Otherwise, all claims for replacement/repair may  
be rendered invalid.  
SERIAL NUBMER. Please take a few minutes and send to  
us a completely filled out warranty card within 14 days of  
the original date of purchase. Otherwise, warranty claims  
may be rendered invalid. Or fill out the warranty information  
1.1.2 Initial operation  
The TRUTHs must be placed on a flat and stable surface.

1.1.3 Warranty  
3.1 Connection  
Please take a few minutes and send us the completely filled  
out warranty card within 14 days of the date of purchase. You  
needed for the registration is located on the rear of the unit.  
Failure to register your product may void future warranty claims.  
2. CONTROL ELEMENTS  
The control elements described in the following are the same  
on both speakers.  
Fig. 3.1: Connecting an amplifier  
Please follow these steps to connect your TRUTHs to a power  
amp: Loosen the plus screw (red ring with a “+”) and the minus  
screw (black ring with a “-”). Now insert the plus cord of the  
speaker cable connecting the amp to your TRUTH into the plus  
opening. Then, connect the minus cable into the minus opening.  
Tighten the screws. Do the same to connect the other TRUTH.  
+
Make sure that all connections are done properly.  
Speaker cables are color-coded to help avoid  
confusion. You’ll know that the signal is inverted  
(i.e. you’ve mixed up the connections) when you  
notice that bass frequencies are getting lost and  
when the stereo characteristic of the signal is  
majorly worse.  
+
Always make sure that bare wire ends never touch  
the open end of another speaker cable, speaker  
connectors or metal parts of your amp.

TRUTH B2030P/B2031P  
The BEHRINGER TRUTH B2030P/B2031P is a so-called near-  
field monitor, which means that the impact of the room acoustics  
on the sound will be reduced considerably owing to the short  
distance between speaker and listener.  
3.1.1 The truth about speaker cables  
Carefully approach the choice of what cables you use. Which  
cables you use can have a major influence on your sound.  
Cables of various lengths and diameters affect the resistance  
value—causing a loss in power.  
On the other hand, that doesn’t mean that you should be buying  
high-end cables that cost as much as your speakers. Simply use  
the following rule of thumb: Whenever possible, use cables with  
large diameters (gauge) and keep the cable length to a minimum.  
The screw clamps on your TRUTH can accept cable thickness  
of up to 7 mm² (9 AWG).  
3.1.2 Amp  
The power rating of the amp you use should be roughly twice  
the load capacity of your TRUTH. Consequently, the B2030P  
should be operated with an amp with a load capacity of 2 x 200  
Watts, and the B2031P with an amp with a load capacity of  
2 x 300 Watts.  
Fig. 3.2: Incorrect speaker setup  
This illustration shows how you shouldn’t do it: you can clearly  
see that a portion of the sound bounces back from the walls  
before it reaches the listener’s ears. Thus, direct and reflected  
sound waves overlap which results in a coloration of the sound.  
Also, you should keep in mind the impedance of your TRUTH in  
order to guarantee optimal power delivery. The B2031P’s  
impedance is 4 , whereas the B2030P’s is 8 . Use an amp  
whose power rating roughly corresponds to the values  
recommended in the table. The impedance should correspond to  
the values listed in the table:

B2030P  
B2031P  
Amp power rating  
200 W into 8 Ohm  
300 W into 4 Ohm  
Tab. 3.1: Recommended amp power ratings  
Of course, you can use amps with higher power ratings.  
However, make sure not to exceed the load capacity of your  
TRUTH. Damage to speaker components caused by exceeding  
their load capacity is not covered by the warranty.  
Fig. 3.3: Correct speaker setup  
3.1.3 Protecting your TRUTH  
To ensure that your B2030P/B2031P last for years to come,  
you should definitely keep the following in mind:  
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 the illustration (i.e.  
woofers closer to each other), to allow for an improved stereo  
image.  
s
Always turn the volume down on your amp before  
switching it on or off.  
s
When powering your equipment up/down, the amp should  
always be the last one to be powered up and the first one  
to be powered down. This way, you avoid loud crackling  
noise that occurs when you turn studio equipment on or  
off.  
s
s
Always make sure your audio signal level is optimally set.  
Avoid overdriving your amp.  
Do not push your studio monitors beyond their physical  
limitations. Even though your TRUTH has sufficient power  
overhead, you can still damage it if you drive it too much or  
crank the volume all the way up for longer periods of time.  
Fig. 3.4: TRUTH setup horizontally  
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.  
3.2 Speaker placement suggestions  
Since the sound of a speaker depends to a great extent from  
its surroundings, placing your TRUTH correctly is very important.  
Please try to follow these suggestions through. Your efforts will  
be rewarded with better sound and higher resolution.  
Both speakers are built identically. There is no need to concern  
yourself with which speaker should be placed left and which  
speaker should be placed right. Place the TRUTHs on a flat and  
stable surface, if possible use a dedicated speaker stand. In this  
way, the speaker is acoustically decoupled and won’t induce  
vibrations in nearby objects, which would affect the bass  
response. If you cannot use a stand, put the TRUTHs on spikes  
or damping foam material. Another aspect is the distance between  
speaker and wall: keep the speaker away from the wall, as this  
would emphasize the bass response, particularly in corners,  
where two walls form an angle.

3.3 Adapting the TRUTH to the room acoustics  
4. SPECIFICATIONS  
To acoustically adapt your TRUTH to your control room, in  
cases when the speakers are located in unusual places or when  
you have specific sound requirements, you may have to use an  
external equalizer. It should be connected in the signal path  
between your mixing console and your amp.

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 TRUTH 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  
an equalizer 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!
