Before you get started1.1

Shipment1.1.1

The TRUTH was 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.
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.

Initial operation1.1.2

Please make sure the unit is provided with sufcient ventilation, and never place the TRUTH on top of an amplier or in the vicinity
of a heater to avoid the risk of overheating.
Before plugging the unit into a power socket, please + make sure you have selected the correct voltage:
The fuse compartment near the power plug socket contains three triangular markings. Two of these triangles are opposite one another. The voltage indicated adjacent to these markings is the voltage to which your unit has been set up, and can be altered by rotating the fuse compartment by 180°.
Caution
This does not apply to export models that were for ex- + ample manufactured only for use with 120 V!

Introduction1.

Congratulations! With our new BEHRINGER TRUTH you have purchased one of the best high-resolution active studio monitors available. It is a tool that reproduces your program material with
highest delity and balance, positioning sound sources accurately
on the stereo basis.
The TRUTH features two separate ampliers for bass and high
frequencies, sporting loads of power reserve. On the bass end, a long-excursion woofer embedded in a sturdy cast-aluminum casing springs into action. The scope is broadened downward
by using a special bass reex system. In the upper frequency
range, a specially developed dome tweeter provides for subtle
signal reproduction. The chassis and the ampliers are protected
from overload using a sophisticated circuitry. The speakers are magnetically shielded, so you can use your TRUTH near computer monitors or TV sets. The audio signal is separated using an active crossover that guarantees accurate frequency separation and perfect tuning of both speakers among each other.
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 rst!
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.
Caution
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.
If you alter the unit’s voltage, you must change the fuse + accordingly. The correct value of the fuse needed can
be found in the chapter "Specications".
Faulty fuses must be replaced with fuses of appropriate + rating without exception! The correct value of the fuses needed can be found in the chapter "Specications".
Power is delivered via the cable enclosed with the unit. All requi­ered safety precautions have been adhered to.
Please make sure that the unit is grounded at all times. +
For your own protection, you should never tamper with
the grounding of the cable or the unit itself.
The sound quality may diminish within the range of pow- + erful broadcasting stations and high-frequency sources. Increase the distance between the transmitter and the
device and use shielded cables for all connections.

TRUTH B2030A/B2031A

Control elements4

Control elements2.
The control elements described in the following are the same on both loudspeakers.
Front panel display elements (here: B2030A)Fig. 2.1:
ON - This LED lights up as soon as you switch on the {1} speaker.
LIMIT - Lights up as soon as one of the built-in protections {2} is activated.
Rear panel connectorsFig. 2.2:
All connectors of the TRUTH face downwards, so as to allow you to place the speaker as closely to a wall as possible.
INPUT - These are the balanced inputs of your TRUTH, laid {3} out as 1/4" TRS and XLR connectors.
The mains connection is achieved via the standard IEC {4} connector. A matching power cord is included.
FUSE COMPARTMENT/VOLTAGE SELECTION - Before {5} plugging the unit into a power socket, please make sure you have selected the correct voltage. Faulty fuses must be replaced with fuses of appropriate rating without exception. Some units feature a fuse compartment that can be oper­ated in two different positions, allowing alternating between 230 V and 120 V.
When using the unit outside of Europe (running on +
120 V), you have to implement a fuse with a higher
rating.
Caution
The POWER switch does not fully disconnect the unit + from the mains. Unplug the power cord completely when
the unit is not used for prolonged periods of time.
The TRUTH should be the last device in the signal chain +
to be switched on and the rst to be switched off. This way, loud switch-on "thumps" that can occur when pow-
ering other equipment on or off can be avoided.
INPUT TRIM controlFig. 2.4:
INPUT TRIM - Use this control to adapt the TRUTH’s input {7} sensitivity to the signal source.
Rear panel control elementsFig. 2.5:
LOW FREQUENCY - With this switch you can adapt the {8} woofer to a subwoofer system or emulate the sound char­acteristics of small speaker systems.
ROOM COMPENSATION - For maximum exibility the {9}
TRUTH features a switch that adjusts the speaker depend­ing on its setup position.
HIGH FREQUENCY - This switch adapts the speaker's [10] frequency response to the damping characteristics of the control room.
The POWER switchFig. 2.3:
Use the POWER switch to power up your TRUTH. The {6} POWER switch should always be in the "Off" position when you are about to connect your unit to the mains.
Rear panel control elementsFig. 2.6:
The following control elements are found only on the B2031A:
POWER MODE - This switch allows you to toggle between [11] "ON", "OFF" and "AUTO" power-up modes (see chapter
3.1). MUTE LOW - Disables the woofer for servicing and main-[12]
tenance. MUTE HIGH - Disables the tweeter for servicing and main-[13]
tenance.
TRUTH B2030A/B2031A
Applications 5

Applications3.

Connection3.1

Use the enclosed power cord to connect the TRUTH to the mains. To avoid ground loops, both speakers and the mixing console should be fed from the same outlet. For your convenience, the B2031A features an automatic power-up system which activates the TRUTH as soon as a signal is present on its input, and deac-
tivates the speaker after signal pauses of more than ve minutes
(only B2031A). Function: The switch for the automatic power-up system (11)
has three positions. When set to OFF, the speaker is completely switched off and cannot be activated with the POWER switch {6}. Position AUTO allows the automatic operation as mentioned above. In position ON, the B2031 is activated all the time and can be switched off only with switch {6}.
Be sure to switch the TRUTH off with the POWER switch + during longer pauses.
Now connect both speakers to your console by means of com­mercial XLR or TRS cables. Since the TRUTH is an active speaker system, instead of conventional speaker cables you will need normal TRS or XLR cables.
Connect the TRUTH to the control room outputs of your console, so as to be able to control the monitoring volume independently of the main mix level. If your console does not have such outputs, you can also use the main mix outputs. However, in this case the speaker volume cannot be set independently of the main mix level, i.e. you must adjust the monitoring volume on the TRUTH. Please consult the operating instructions accompanying your console to
nd out whether it has balanced or unbalanced outputs. Connect
these outputs to the TRS or XLR {3} input. If possible use the balanced connectors, so as to avoid interference and hum. It won’t help, however, to connect unbalanced outputs with balanced
inputs. The benets mentioned above will apply only when both
inputs and outputs are of the balanced type.
Be sure to mute the signal sources before you put the + TRUTH into operation.
Once the TRUTH has been connected as described above, you can activate the speaker with the POWER switch.

Speaker placement suggestions3.3

Since the sound of a speaker depends to a great extent on 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 TRUTH on a at 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 TRUTH 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.
The BEHRINGER TRUTH B2030A/B2031A are so-called near-
eld monitors, 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.
Incorrect speaker setupFig. 3.1:
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 reected sound waves
overlap which results in a coloration of the sound.

Level setting3.2

When the TRUTH has been connected properly and switched on, you can now turn up the console output that feeds the B2030A/B2031A. Provided you have a signal source connected, you now hear the audio material as it is played back by the TRUTH. The INPUT TRIM control {7} on the rear panel is set to 0 dB ex­factory, i.e. unity gain, which is okay when you feed the TRUTH from a pro-level console. In this case, the TRUTH automatically operates at maximum level, provided that your console has been set up correctly and its output is set to 0 dB.
The LIMIT LED {2} helps you control the level. It lights up as soon as overloading causes one of the internal protections to respond. The TRUTH doesn’t get damaged when the LIMIT LED lights up with occasional signal peaks. However, please make sure that it won’t light up all the time, because sooner or later this will activate the thermal protection system and temporarily mute the built-in
ampliers, to warn you that you are driving the TRUTH too hard.
If so, you can reduce levels either on your console or using the INPUT TRIM control {7}. If the outputs on your console don’t provide studio-level signals, you can turn up the INPUT TRIM control. If you connect the TRUTH to the preamp output of your stereo system, it may also be necessary to raise the level on the TRUTH itself. To build up a rudimentary stereo system, you can directly connect the outputs of a CD player to the TRUTH’s inputs, and use the CD player to adjust the volume.
The TRUTH is capable of producing high volume levels. +
You should mix your recordings at moderate levels, so
as to avoid listening fatigue and hearing impairment.
Correct speaker setupFig. 3.2:
This effect can be reduced by turning the speakers towards the
listener. To make reections from ceiling or oor 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 gure 3.3, to allow
for an improved stereo image.
TRUTH setup horizontallyFig. 3.3:
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 reective. 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 poten­tially impaired sound by optimizing the loudspeaker placement beforehand.
Rear panel legendingFig. 3.4:
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 specic 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- speak­ers, 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.
Installation4.
The BEHRINGER TRUTH features one balanced XLR and one bal­anced 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.
