Original Advanced True Diversity Digital Wireless DJ Karaoke Stage Sing Microphone AD4D System AD2 KSM8 Handheld High-Class Mic

 

Features:

1. True diversity receiver, dual-channel independent selection system. It can minimize the occurrence of frequency interruption.

2. The dual-channel independent AFS frequency automatic search function can quickly scan and lock the frequency with the least

worry in the working environment.

3. Receiver and transmitter use IR infrared frequency matching technology to synchronize codes with one click.

4. Professional performance-level phase lock circuit, combined with noise lock squelch control and digital pilot technology, when

the transmitter is turned off, the pilot control mutes the AF signal to suppress noise, and at the same time mutes the

corresponding receiver. It guarantees the effective blocking of the worry signal.

5. Backlit LED display indicates the working status of RF and AF signal strength, battery status, diversity channel indication

(A/B), frequency, frequency group/channel, etc.

6.Accurate electronic volume control technology, the receiving distance is adjustable in three gears, and has an operation key

lock function to prevent misuse.

7. TRD.3 true diversity wireless system is specially designed for touring and fixed installation purposes, and provides a variety

of sound heads with different sound properties for replacement. It has the highest reliability, sound quality and transmission

stability.
