Introduction; The Concept; Before You Start - Behringer TRUTH B2031 User Manual

1. INTRODUCTION

Congratulations! With our new BEHRINGER TRUTH B2031 you have purchased one of the best high-resolution
active 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.
We recommend that you experiment with your B2031 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!

1.1 The concept

The B2031 is equipped with two separate power amps for the woofer and tweeter ranges. With 150 and
75 Watts respectively, these amps have lots of power reserves. In the low-frequency range we used an 8 ¾"
soft-suspension speaker with a sturdy cast aluminum chassis. Its effective operating range is expanded
downwards by a special bass reflex system. The innovative shape of the reflex tunnel reduces airflow noise
even at highest sound pressure levels. In the high-frequency range a titanium-dome tweeter ensures an extremely
fine signal resolution. Sophisticated circuitry is used to protect both chassis and amplifiers against overloading.
Both speakers are electromagnetically shielded, so that you can operate the TRUTH in close proximity to your
computer monitor or TV set. The individual frequency ranges driving the speakers are derived by means of an
active crossover network, which allows for the precise separation of frequency bands and the perfect adaptation
of two speakers to each other. Rear-mount switches enable you to configure the crossover networks, so as to
adapt the speakers to specific room acoustics. More on this later.
High-quality components and design
The philosophy behind BEHRINGER products guarantees a no-compromise circuit design and employs the
best choice of components. The operational amplifiers 4580 which are used in the TRUTH B2031, are
exceptional. They boast extreme linearity and very low distortion characteristics. To complement this design
the choice of components includes high-tolerance resistors and capacitors, high-grade switches and several
other stringently selected elements. Additionally, the TRUTH is manufactured in compliance with the ISO9000
certified management system.

1.2 Before you start

Your TRUTH was carefully packed in the factory and the packaging is designed to protect the unit from rough
handling. Nevertheless, we recommend that you carefully examine the carton and its contents for any signs of
physical damage, which may have occurred during transit.
If the unit is damaged, please do NOT return it to BEHRINGER, but notify your dealer and the
shipping company immediately, otherwise claims for damage or replacement may not be granted.
Shipping claims must be made by the consignee.
The TRUTH must be placed on a flat and stable surface. Be sure that there is enough air space around the
unit for cooling and please do not place the TRUTH on high-temperature devices such as power amps, etc. to
avoid overheating.
Before you connect the TRUTH to the mains, please make sure that your local voltage matches
the voltage required by the unit!
Please use the enclosed power cord to connect the unit to the mains. The cord complies with all applicable
safety standards.
Please note that all units must be grounded properly. For your own safety, you should never
remove any ground connectors from electrical devices or power cords or render them
inoperative.
