CTRLPA sound waves to disperse system

2016-11-11 15:20:36

The world's largest military radio speakers

The military radio loudspeaker is located in fujian province xiamen xiang Ann area DaDengDao war hero three island

sightseeing garden, the military radio loudspeaker maximum diameter of 2.88 meters, 4.74 meters long and weighs

1588 kg and peak power of up to 20000 watts, effective sound transmission distance of 12 km, is the 60 s and seventy

s last century military confrontation across the Taiwan straits, set up to broadcast on kinmen, now into a tourist attraction.



The "cheonan" incident inter-korean shout to each other

"Cheonan" incident in 2010, south Korean military border region in 11 post resetting loudspeaker equipment, these

loudspeakers broadcast night covering 24 kilometers, covering 12 kilometres during the day, after 80, Mr Kim jong UN

had try so hard, the more you know?



What is the remote strong directional sound system?

Remote directional strong directional transmission equipment, sound system is a kind of can realize long-distance propaganda,

warning, deterrence and disperse the target noise, etc. Can be extremely remote, even through some buildings unusual clarity

of sound effects, highly directional, loudly, such characteristics as high definition, ensure the validity of the voice transmission

over a long distance and accuracy, little impact on surrounding unrelated areas, has been the China and the United States and

other nations, police as non-lethal disperse weapons, in the gulf of Aden escort ships are equipped with such devices, and played

a huge role in anti-piracy operations.



CTRLPA special strong sound system

As the world increasingly changed international situation, countries' armed forces and civil security in the face of unprecedented

challenges, such as Ken zhuo stake against military field (the armed forces inside intelligent management, frontier defense, coastline,

prisons, and surveillance law enforcement and the armed police, special police, traffic police three p internal intelligent management,

vehicle propaganda broadcast, strong voice to disperse and other equipment); Biochemical leakage, emergency rescue, emergency

plan system (mountain torrent disaster, typhoon, tsunami, air defense early warning, etc.) of the alarm, emergency broadcasting,

intelligent management application, developed a series of mature, stable, audio amplification system, especially in the field of Gao

Qingjiang sound broadcast, strong voice to disperse a deeper research.


Remote Gao Qingjiang sound device  CT9060HD

All design, made the shell of the aerospace technology, with super weatherability and riot

Remote Gao Qingjiang sound (60 w) / 3.0 1.0 (180 w) / 6.0 (360 w) / 9.0 (540 w) / 12.0 (720 w) in the condition of

strong noise, 100 meters instantaneous sound pressure level of up to 100 db/db/db/db / 118 112 104 122 db, 1 km

far sound pressure level of up to 78 db/db/db/db / 92 86 86 80 db, voice clarity of 0.85 or higher

Remote Gao Qingjiang acoustic sensor does not like ordinary speaker for sound propagation in spherical form and the

Angle can be realized by adjusting the array fan radiation (e.g., hang seng to spread) or focus acoustic radiation (such

as beam directional propagation)

When there are obstacles block, this array acoustic field has the strong ability of diffraction, so after obstruction of sound

shadow area is relatively small, which can realize long-distance call, warning, deterrence function. Has the characteristics

of directional, high pressure, high definition

Used for early warning, search, emergency rescue, patrol, border and coastal defense, prison management, barracks, or

used for police work (including the implementation of the broadcasting channel, traffic and crowd gateway control, blockade,

to set up checked posts, lock up, move to disperse, etc.), the device has the very high value

Military police car/portable sound to disperse. Alarm. Propaganda system   CT/SR882

With siren, propaganda, MP3, bluetooth function, fixed resistance or constant pressure output level before and after the power

amplifier in the merger of the series power amplifier

Can splice U disk, SD card, such as bluetooth receiver memory devices MP3 audio source

Using new circuit design, power grid wide adaptability, low static power, machine vibration noise is low, low output noise,

distortion of the output is small

High energy efficiency, small size, light in weight

Automatic protection of heat dissipation system, a cooling fan to produce noise is small, the fan life dramatically, extended

Resistance and constant voltage output, the maximum transmission voltage 100 v

Unable to connect to control has a low profile functions, communicating with, can be inserted into the receiver directly

Handheld electric megaphone a key lock key function, all buttons equipped with LED lights, lights on a white background,

facilitate environmental homework at night

A set of total volume knob control, improve the machine self protection function

Army green need special customized
