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 column speakers R60, R100 and R200. A specific technical manual is devoted
to the Ray-On Mini.
Using the DGRC principle ensures an optimal sound coverage and intelligibility on the listening zone; it is illustrated
in figure 1. For every model, the range depends on the installation height (see section 2).
Figure 1 – DGRC principle illustration
Ray-On loudspeakers are ideal for speech reinforcement in small to large spaces where the listening zone is hori-
zontal (slope < 5°). 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.
Models R60TC, R100TC, and R200TC 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.
Figure 2 on the facing page shows the ±5dB range1versus to the mounting height, for the direct field2at mid-
frequencies (300Hz-3kHz).
1Range for a standing audience shown. For a seating audience, take off 40cm to the column height.
2Taking the reverberated field into account minimizes the influence of the floor’s material.

Figure 2 – ±5dB range (m) according to mounting height (from floor to bottom of column, in m).
Table 1 on the next page gives the minimum, maximum, and nominal values for Ray-On mounting height3.
3Ears are at 1.15m from floor for a seated audience, 1.55m for a standing audience.

The Ray-On wall-mounting system allows the subsequent adjustment of the columns height.
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 10.
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.
The recommended equalization is the same for the 3 different models, which allow many columns to be put together
on the same 100V line.
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 2 on the next page gives detailed information about these equalizations.. The corresponding frequency
curves are presented in figure 3 on the facing page.

Type Parameters
1 Parametric Freq = 100 Hz ; Gain = +6dB ; Width = 1.5 oct (Q=0.92)
2 2nd order high-pass Fcut = 130 Hz ; Gain = -3 dB @ Fcut (Butterworth)
3 Parametric Freq = 280 Hz ; Gain = -3.0 dB ; Width = 1.0 oct (Q=1.4)
4 Parametric Freq = 5 000 Hz ; Gain = +6 dB ; Width = 1.0 oct (Q=1.3)
5 Parametric Freq = 10 700 Hz ; Gain = -7.0 dB ; Width = 0.25 oct (Q=4.0)
6 Parametric Freq = 15 500 Hz ; Gain = +6.0 dB ; Width = 0.5 oct (Q=1.2)
Table 2 – Recommended equalization
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 next
two pages illustrate the steps to follow for column mounting.
An accessory is available for mast mounting.
Height adjustment: If changing the column’s height is necessary, take the column off its wall-mounting
system, move the «hook-slide» along the backside rail, then put the column back on its wall-mounting system.
100V: Power selection is made on the connection terminal.
Safety: An M5 thread is available at the back of the column designed to accommodate a ring for mounting a
safety cable.
«Daisy-chain» cabling: Two bushings are available on the back of the Ray-On columns, the second one
being used to connect the column to an other Ray-On.
Good to know: The cable diameter must be less than 7.5 mm, the wire’s between 0.5 and 2.5 mm².
