We have configured various radio slightly according to the use needs of various occasions in the school: remote horn slightly for playground sound reinforcement, linear sound columns for conference room sound reinforcement, wall-mounted slightly in classrooms, etc. All slightly are customized according to outdoor work requirements and have high-level waterproof and dustproof capabilities. The white appearance is adopted to avoid aging and cracking of the shell caused by long-term exposure, and the service life of the equipment is extended. The installation structure must be firm and reliable, equipped with special anti-rust brackets and fixing parts to withstand the influence of external forces such as strong winds and prevent slightly from falling off. Anti-oxidation terminal and corrosion-resistant internal components are used inside the slightly to avoid short circuit or poor contact caused by wet environment. Ensure safe and stable operation in any weather.
