Wireless microphone PCB circuit board circuit board design development production features:

1. With advanced infrared automatic frequency, pilot function (both easy to operate, but also to prevent crosstalk phenomenon).

2. The use of distance can be manually adjusted (receiver and transmitter have distance control keys).

3. No noise when used, high-fidelity sound transmission circuit to ensure the clarity and reducibility of sound.

4. The hand microphone adopts the most advanced booster circuit at present, which effectively extends the service time of the battery.

5. 400 channels, according to different regional environments, can be used in the same occasion at the same time 50 ~ 100 sets, especially for KTV rooms.

6. Use multiple squelch control circuits on the receiver to effectively prevent interference from external signals.

7. No switch impact sound, to ensure the safety of the post-amplifier and speaker.

8. Transmitter hand and receiver are equipped with LCD display, the working state is clear at a glance.

The above configuration information is for reference, our company can match parameters according to different wireless microphone control boards, different use environments, different functional requirements, and can issue hardware configuration books.

As long as you put forward the functional requirements for the product, or even just an idea, we can design the control circuit of the product according to your requirements to achieve the functions you want.
