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

Product introduction

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.
