Product description
1. Traditional circuit board is adopted, with long receiving distance and strong receiving stability.
2. Automatic frequency search function, automatically search the cleanest channel frequency in the working environment.
2. Multiple noise control circuits are used on the receiver to effectively prevent the interference of bounded signals.
3. Adopting PLL combination technology and digital pilot technology, easy to operate.
4. Single channel LED function large font display, clear working status.
5. Electronic volume control, higher accuracy, very good elimination of potentiometer noise resistance
6. Adopt audio compression technology circuit, with wide dynamic response, transparent analytical force and perfect sound quality effect.
7. Use high sensitivity microphone core, built-in suppression circuit, effectively reduce the microphone roar.
8. No switch impact sound to ensure the safety of the power amplifier and speaker at the rear stage.
9. Transmitter microphone and receiver are equipped with LIQUID crystal display, built-in high and low two-stage power switching technology, which can be adjusted according to different working environment.
10. The handheld adopts the boost circuit design, which effectively extends the battery life
