B300
5. APPLICATIONS
5. APPLICATIONS
5.1 Presentations
Owing to the built-in microphone preamp you only need a B300 and a dynamic microphone to set up a
straightforward sound reinforcement system. Mount the B300 on a speaker stand for optimum presentation
and intelligibility of announcements. If one B300 is not enough, you can of course use a second or even more
loudspeakers. How to wire them is shown in chapter 3.2.2.

5.2 P.A. systems
P.A. is short for “public address” and includes all applications that involve a larger audience. Such a system
can be composed, for example, of the elements described in chapter 3.2.1. In this case, you would connect
microphones, playback devices, effects, etc. to your mixing console.
To increase the sound pressure level, simply add some speakers on each side of the stereo basis. For
instance, you could use two B300’s on each side and place them next to or on top of each other. The cutouts
in the cabinets guarantee safe stacking.
In this application you would use the LINK OUTPUT to connect one B300 to the XLR input of the second on the
same stereo side.

With several B300’s connected to each other, their input impedance will be reduced by half
(two B300’s), or to one third (three B300’s), etc. Always use the output impedance of the mixing
console as a basis for your calculations!
5.3 Monitoring application
In contrast to P.A. speakers, stage monitors are used to radiate the sound directly to one specific performer.
When the performer uses a microphone, it is often difficult to set up the monitor speaker, because the distance
between B300 and microphone tends to be very short, which can lead to feedback problems. To avoid this
effect, both microphone and monitor speaker must be placed carefully. Some hints on this can be found in
chapter 2.2.
In a monitoring application, the B300 is provided with the monitor or aux output signal from a mixing console.
If you wish to use further B300’s, you can loop through the audio signal using the LINK OUTPUT on each B300.
Sound and volume of each B300 can be controlled with the help of the controls (VOLUME), (HI) and
(LO).

If you encounter persistent feedback problems, consider using our proven BEHRINGER
FEEDBACK DESTROYER PRO DSP1124P for line-level signals. For signals with line or
microphone level we recommend our BEHRINGER SHARK DSP110.
