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.
Table 1gives the minimum, maximum, and nominal values for Ray-On Mini mounting height1.

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 6 on page 8.
1Ears are at 1.15m from floor for a seated audience, 1.55m for a standing audience.

4 Equalization and tuning
Ray-On loudspeakers may be used without any equalization, but using one is advised. Equalization flattens the
column’s frequency response and protects the loudspeakers by filtering low frequencies.
Two equalizations are specified:
• one for speech, which uses 4 cells (n°2-5);
• the other for music, which uses 6 cells (n°1-6).
The table 2gives detailed information about these equalizations.. The corresponding frequency curves are pre-
sented in figure 1.
Type Paramètres
1 Parametric Freq = 100 Hz ; Gain = +6 dB ; Width = 1.5 oct (Q=0.92)
2 2nd order high-pass Fcut = 130 Hz ; -3dB @ Fcut (Butterworth)
3 Parametric Freq = 190 Hz ; Gain = -3.0 dB ; Width = 0.4 oct (Q=3.6)
4 High-Shelv Freq = 1800 Hz ; Gain = -5.0 dB
5 Parametric Freq = 3600 Hz ; Gain = +5 dB ; Width = 0.5 oct (Q=1.3)
6 Parametric Freq = 15 500 Hz ; Gain = +6.0 dB ; Width = 0.5 oct (Q=1.2)
Table 2 – Recommended equalization. Voice: cells 2-5. Music: cells 1-6.
If a subwoofer is used, it is advised not to activate the cell 1, frequencies under 180Hz being rendered by the sub.
This allows the columns to not be driven with important levels of low frequencies.

5 Installation and Wiring
Ray-On loudspeakers are vertically mounted, usually on a wall, using the supplied wall-mounting system. The
previous two pages illustrate the steps to follow for column mounting.
100V: Power selection is made on the connection terminal.
