Long-distance Directional Single Sound Wave Loud sound Drive Away System

Long-distance Directional Single Sound Wave Loud sound Drive Away System

Product Introduction:

WH-QS2B/33 remote directional sound wave strong sound removal system

The WH-QS2B/33 Long-distance Directional Single Sound Wave Loud sound Drive Away System is based on the strong directivity propagation of sound waves and emits powerful, loud and ultra-high decibel harsh noise within a certain coverage angle. It has high sound pressure level, strong directivity and clear sound. 

The effect distance is long, causing discomfort symptoms to the listeners and acting as a deterrent, thereby achieving the purpose of driving away. When working, it emits a directional sound wave with a beam angle of 10°×15° @2.5kHz/-6dB, which can broadcast clear voice information and high-intensity warning sounds (either real-time voice or pre-recorded voice), and the sound transmission distance is the longest Up to 1000 meters (STI-PA): ≥ 0.85, and the sound is highly directional: the sound in the forward area is clear and attenuated, and the sound in the rear and surrounding areas attenuates quickly and has little interference. 

This product also has a high-power amplifier function and can be used for emergency broadcasts, shouting, playing prefabricated sound sources, etc. It can also be used in large-scale publicity activities.

Product Features:

◆ Rated power: 200W, constant voltage input: 70/100V audio;

◆ Beam width (H×V): 6.10° ×15° @2.5kHz/-6dB;

◆ Frequency response: (300-10000) Hz, maximum sound pressure level: 148dB±3dB;

◆ The turntable can rotate 360° horizontally and ±50° in pitch, and is windproof, waterproof and earthquake-resistant;

◆ All-weather design, the shell is made of aerospace industry technology, resistant to acid and alkali, salt spray, and can withstand high-intensity impact and vibration. It has a windproof level of 12 and a protection level of IP56;

◆ The test conditions are: normal temperature (25°C), relative humidity of 20%, no wind, and free sound field. The maximum peak output sound pressure level at 1 meter can reach 148dB, the effective dispersion distance is 100 meters (100 dB), and the voice transmission distance is 1000 meters (78 dB);

◆ Sound is transmitted in a concentrated beam with sharp directivity. Within the effective dispersion range of the sound beam axis, it can cause auditory pain or even cause hearing loss in a short period of time.

◆ It has multiple functions such as shouting and playing sound sources, with clear and loud sound and long range;

◆ The wide dynamic range formed by the combination of the power amplifier operating power supply and the speaker protection circuit provides guarantee conditions for efficient electroacoustic conversion;

◆ The sound is highly directional: the sound in the forward area is clear and has low attenuation, and the sound in the backward and surrounding areas is rapidly attenuated with little interference;

◆ The design of high-efficiency electro-acoustic conversion system (standard sound pressure level + high-efficiency beam energy speaker) achieves the design goal of high sound pressure level/low driving power consumption.

Host System Functions:

◆ The call has the highest priority and has the low-profile call function.

◆ High-definition voice and sound effects.

◆ Low temperature resistant LCD display.

◆ The function keys have backlight function, making it easier to work at night.

◆ One USB interface supports MP3 WAV format file playback.

◆ One-click recording.

◆Support Bluetooth audio reception and playback.

◆ One microphone input interface.

◆ One line input interface, controlled by the overall volume adjustment.

◆ One line output interface, the output size is affected by the microphone volume and total volume adjustment.

◆ Independent knob for total volume.

◆ DC10.8-30V wide voltage power supply interface, wider adaptability.

◆ All the way to the military anti-noise wired microphone.

◆ The wireless microphone is defaulted at startup, and the wired microphone has the highest priority.

Scope of Application:

Official ship law enforcement, urban commanding heights, border and coastal defense, waterways, airport bird repellents, vehicle patrols, prisons, military exercises, anti-terrorism, etc.
