This model of speaker is installed on the ceiling, simply connecting with VISSONIC conference controller by CAT5 cable to provide power and audio signal. It is used to convert the input audio electric power signal of the power amplifier (referred to as the power amplifier or amplifier) into a sound power signal and then broadcast it through the ceiling speaker in the form of sound waves. Ceiling speakers are widely used at Office buildings, hotels, and shopping malls are public places that use ceiling speakers.
It's suitable for high-end performances, conferences, evenings and concert system.
