DPS 40 F - 100 V (RAL 9006)
Art. No. 50294
The DPS 40 F - 100 V dipole flat-panel loudspeaker has been developed and optimised specifically for applications in the open-air with limited adjoining reflecting surfaces (such as ceilings). It focuses the sound to a great extent in a horizontal direction, so neighbours or adjacent station platforms only receive much reduced signals than would be the case with classic horn speakers. Sound field simulations coupled with measurements under real-life field conditions demonstrate that there is a difference in the level of interference noise to the sides of the platform of 6 to 8 dB in favour of dipole flat-panel speakers. At the same time, their efficiency is considerably higher, which means that typical horn speakers would require eight times the amplifier output to achieve the same sound pressure on a railway platform.
Versions: Models with one side closed e.g. for use at the ends of platforms.

Railway station PA speakers
A key objective of public address systems in railway stations is to ensure that every message relating to railway operation and in emergencies is clearly audible to all travellers at the target location in the station. DIN EN 60268-16 sets ambitious standards for speech intelligibility because the acoustic environment on railway platforms is a difficult one.
- Trains arriving and leaving generate very loud ambient noises and require the loudspeakers to have a correspondingly high loudness level
- Announcements on adjacent platforms make other announcements unintelligible unless the sound is properly and effectively restricted to the required target area
- Sound reverberating from the sound-reflecting ceilings and walls in enclosed station buildings generates interference noise that makes the announcement hard to understand.
The passive train station loudspeakers made by VISATON will, however, allow the required speech intelligibility to be achieved, despite the difficult surroundings. These speakers are dipole flat-panel speakers, and provide the required high levels of sound pressure while focussing the sound they produce more accurately than classic speaker systems.
A dipole speaker works by creating air movement (as sound pressurewaves) directly from the front and back surfaces of the driver, while the amount of sound emitted to the sides, up and down is much reduced. An arrangement of several loudspeakers in line or in a single plane results in an even more closely focussed sound image. By combining these two principles, VISATON has achieved a targeted improvement in the polar characteristics of loudspeaker systems.
Thanks to this principle, the platform in front of and behind the loudspeaker is addressed and the adjacent platforms hardly hear any of it. The sound also hardly reaches the ceiling and floor so interfering reverberations that would reduce speech intelligibility are reduced.

EX 60 R - 8 Ohm
Electro dynamical exciter for stimulating bending waves on plates. The unit can be attached to the surface of the plate by gluing or screwing.

*) Maximum long term power according to DIN EN 60268-5
KL 33 - 100 V (black)
33 cm spherical loudspeaker as bass reflex system. Equipped with one 17 cm bass/midrange and four midrange/highrange drivers which have a good directivity pattern at off-axis angles and therefore provide a uniform and pleasant sound quality. The KL 33 can be connected to a 100 V network or a normal amplifier (4 ohm).

WF 130 ND - 8 Ohm
13 cm (5") low-midrange driver with Polypropylen membran, neodymium magnet and rubber surround which is suited well for uses where very low installation depth and low weight is required but good sound cannot be renounced in the bass and midrange tone area. The basket front has an integrated fabric grille, which makes a real grille unnecessary and protects at the same time the usually bare airgap, as well as the voice coil.
B 100 - 6 Ohm
10 cm (4") high-end full-range loudspeaker with excellent balanced response characteristics and slightly increasing high-range for a pleasant sound even outside of 0-axis. High efficiency with low distortion are just some of the qualities of this speaker.
FRS 7 A - 8 Ohm
6.5 cm (2.5") fullrange speaker with balanced frequency response and very good highs. Especially suitable as built-in speaker for music reproduction and as driver for 100 V network column speakers. Outstandingly high efficiency compared to the small size. Equivalent to model FRS 7 - 8 Ohm, but with connectors 2.8 x 0.8 mm (+) and 2.8 x 0.8 mm (-).
