B300
1. INTRODUCTION
Congratulations! With our new BEHRINGER B300 you purchased an absolutely reliable and versatile active
loudspeaker system. You now own an audio tool that gives you an undistorted and well balanced reproduction
of your program material, be it for presentations, P.A. system or monitoring applications. Despite its built-in
high-power stages, the B300 is compact enough to be handled with ease. It combines the benefits of easy and
fast installation and handling with absolutely pro-level features. And the use of matching components (preamps,
crossovers, power amps, speakers) gives you the freedom to use your B300 in a great variety of applications.
+ This manual first describes the terminology used, so that you can fully understand the B300
and its functions. Please read the manual carefully and keep it for future reference.
1.1 The concept
The B300 is equipped with two separate power amps for the woofer and tweeter ranges. With 175 and 50 watts
respectively, these amps have lots of power reserves. The effective operating range of the 15" woofer has been
expanded towards the bottom end by means of a special bass reflex system. The tweeter installed in the B300
ensures an extremely fine signal resolution in the treble range. To optimize its efficiency we upgraded the
tweeter with a specially designed horn. A built-in musical limiter makes sure that both speakers are protected
reliably against overloading.
The philosophy behind BEHRINGER products guarantees a no-compromise circuit design and employs the
best choice of components. Additionally, the B300 is manufactured in compliance with a ISO9000 certified
management system.
1.2 Before you begin
Your B300 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 packaging 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 B300 must be placed on a flat and stable surface or a commercially available speaker stand. Be sure that
there is enough air space around the unit for cooling and please do not place the B300 on high-temperature
devices such as power amps or radiators, etc. to avoid overheating.
+ 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.
1.2.1 Mains voltage
Before you connect the B300 to the mains, please make sure that your local voltage matches the
voltage required by the unit! The fuse holder on the female mains connector has 3 triangular markers, with
two of these triangles opposing each other. The B300 is set to the operating voltage printed next to these
markers and can be set to another voltage by turning the fuse holder by 180°. CAUTION: This instruction
does not apply to export models exclusively designed, e.g. for 115 V operation!
Please use the enclosed power cord to connect the unit to the mains. The cord complies with all applicable
safety standards.
