Pumping out 200 Watts of ‘real’ dB power, unlike other offerings that are rated at 200 Watts as that is how much power they consume rather than reflecting how loud they actually are. The MCS-DDSA 200W Digital Siren is unlike any other amplifier currently on the market.
It can produce two different siren tones at the same time giving a ‘two vehicle’ effect via 2 x 100 Watt speakers, or scrolled siren sounds via a 1 x 200 Watt speaker, plus, if required either ‘simultaneously or separately’ a low frequency rumble sound via 1 or 2 x low frequency 200w rumble speakers (rumblers).
With circuitry based on Class D digital siren technology this device is optimised to produce a true 200 Watt output or if preferred 2 x 100 Watt outputs with or without the optional low frequency rumble effect.
The 200W Digital Siren can be controlled with conventional switches via on/off controls, in conjunction with the Horn Ring Transfer (HRT) feature if required and/or via CAN Bus signals for other complementary MCS controllers and switch units.
Low Frequency Rumble Tone Feature
This contributes to improving emergency vehicle operator and public safety especially in urban environments with high density heavy traffic and pedestrians. Also aids with clearing junction/intersection passage.
When used with the LSP-108 digital speaker to optimise the low frequency tones generated from the siren amplifier the output is a highly distinguishable ‘Rumble’ sound. As the sound is notably different to the standard siren tones that everyone is now familiar with this immediately gets peoples attention as well as creating a better sense of the direction the vehicle is coming from.
As the speaker is of a specialised nature, and should ideally be fitted in pairs, it is important that they are fitted correctly to take full advantage of the ‘GROUND’ effect. As such it is mainly appropriate to larger vehicles such as fire appliances and larger 4×4’s.
