Active Outdoor Directional Speaker HSK-X80D

Background: The traditional campus broadcasting system usually uses high-power speakers, and the sound spreads in all directions, which not only affects the teaching quality, but also causes noise interference to the surrounding residents, leading to complaints and complaints.With the transformation of education towards wisdom, the optimization of acoustic environment has become a key element to enhance the campus cultural atmosphere and teaching experience. Optimizing the campus sound environment and eliminating noise interference has become an important measure to promote the process of education intelligence.HSK-X80D active outdoor directional speaker can helpfully solve the problems,which can be through the directional sound technology, the sound is mainly transmitted in the playground, reducing the interference to the surrounding residential areas.It can achieve sound field balance, improve speech clarity and intelligibility. It can meet the requirements of current environmental protection and energy conservation policies, reducing energy waste and operating costs.‌ Features:

• Ideal solution for school,campus;
• Adopt the leading beam forming audio technology, built-in 16-channel DSP digital processing technology;
• Built-in 16 channels Class D digital power amplifier, each channel power 10W, positive effective power up to 80W;
• Built-in 16pcs Neodymium High Sound Pressure Full-range Speaker, each unit can be directional adjustment;
• Designed with an array deployment and utilize directional sound algorithm technology to adjust the sound projection angle;
• Dual-sided speaker design with back-facing configuration, employing sound field reconstruction technology to control the front and rear sound fields;
• By using the back speaker unit to counteract the sound from the front to the back, the sound pressure value on the back is greatly reduced, and the front sound field is strengthened to achieve a super high sound pressure difference in the front and rear directions of the sound column;
• Through DSP tuning, the direction of the main beam of the sound column can be controlled to accurately cover different areas;
• Adopting all aluminum alloy integrated molding treatment and IP66 waterproof design, it meets all-weather outdoor use;
• Built in 6 fixed directional sound effects modes, one click switching according to the on-site environment, convenient and practical;
• Supports 3 types of signal inputs: 1 RJ45 network input(optional), 1 line input, and 1 constant voltage input (70V or 100V);
• Adopting networked design, standard RJ45 interface, supporting LAN/WAN and other network applications;
• AC220V power supply, built-in 6KV lightning protection design circuit, greatly reducing the damage caused by induced lightning strikes to equipment;
• Designed with AC180-250V wide voltage switching power supply
