1 General Presentation
The Ray-On column loudspeakers are passive, and based on the DGRC principle. The range includes three column
models, and a proximity speaker:
• R60, height 60cm;
• R100, height 1m;
• R200, height 2m;
• Ray-On Mini, a proximity speaker.
This technical manual is for Ray-On Mini. A specific technical manual is devoted to the R60, R100, and R200
columns speakers.
The Ray-On Mini is a proximity speaker dedicated mainly to voice reinforcement and ambient music in small venues.
Made of aluminum, Ray-On loudspeakers can be installed outdoor. They are suited for airports, railway stations,
churches, conference rooms, shopping malls, amusement parks, etc.
The Ray-On Mini speakers are compliant with standard EN5424 type B. They can be used in PA systems for safety
announcements.
2 Positioning
The most important parameter for the installation of Ray-On loudspeaker is its mounting height because the range
of the column directly depends on it.

3 CAD Modeling
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 loudspeakers can be predicted directly using CATT-Acoustic or EASE softwares.
A simple direct sound simulation tool is directly accessible on
www.activeaudio.fr
.
Direct sound prediction is also given in the technical characteristics section
