1 General presentation
The Ray-On B70 sound bar is designed for the sound reinforcement of narrow spaces
such as:
-Corridors, escalators
-Shopping alleys
-Shopping malls
-Railway platforms
B70 will also ensure the sound reinforcement of spaces with limited coverage
areas, such as:
-Video-conferencing equipment
-Huddle rooms
-Small spaces in museums
The arc position of the drivers allows a perfect directivity control in the spatially and in
the frequency domain.
This directivity control allows to limit the sound disturbance in the sound reinforced
spaces' neighbourhood.
2 Positioning
The B 70 sound bar is horizontaly mounted, above the area to be sounded in transverse
direction as shown in figure 1
The width of the zone to be sounded and the recommended space between the
loudspeakers is given by the mounting height. Picture N°2 gives these values in function
of the mounting height.

3 Modeling CAO
There are powerful CAD software tools that can predict the acoustics of a room and
accurately model the radiation of loudspeaker arrays. These tools can calculate
various acoustic indices, such as reverberation time, sound pressure level, STI, etc.
The sound radiation of the Ray-On B70 loudspeaker can be predicted directly using
CATT-Acoustic™ or EASE software.
4 Equalization and tuning
Ray-On B70sound bar may be used without any equalization, but using one is advised.
Equalization flattens the loudspeaker’s frequency response and protects the drivers by
filtering low frequencies.
The table 1 gives detailed informations about these equalizations. The corresponding
frequency curves are presented in figure 3 on the facing page.

5 Installation and Wiring
Ray-On B70 is horizontally mounted, usually on a wall or hanged from the ceiling,
using the supplied mounting systems. The next two pages illustrate the steps to follow
for the mounting.
