Specifically designed for karaoke rooms, it has the following characteristics:
* UHF high frequency band is adopted, and 200 frequency bands are randomly selected to avoid interference.
* up to 100 private rooms can be used at the same time.
* the normal operating range is up to 300 meters in diameter without blocking.
* double channel and double reception, equipped with super antenna, the project installation is convenient and beautiful.
* the handheld microphone USES a double switch to eliminate the noise before it is finished.
* use the computer to control the lock frequency to prevent frequency drift.
* equipped with international standard chassis parts.
* elastic net head, anti-fall/anti-fall. The structure is extremely durable, easy to change and easy to maintain.
* double channel receiving circuit is built in the metal cabinet, with strong, heat resistant and professional quality of isolating harmonic radiation interference.
* with the mute control of "sound code and radio frequency intensity", it can prevent the interference of radiating noises such as music counting machines, computers and DVD optical disc players.
