Product Description

Dual Channel True Diversity UHF Wireless Handheld Microphone WIth Shu-re Capsule For Stage Performance

 

Features:

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

2. Dual channel independent AFS frequency automatic search function, which can quickly scan and lock the frequency with the least interference in the working environment

3. The receiver and transmitter use IR infrared frequency matching technology to synchronize the code with one click

4. Professional performance level phase locking circuit, combined with noise locking noise control and digital pilot technology, when the transmitter is turned off, the pilot control mutes the AF signal to suppress noise, while also silencing the corresponding receiver. It ensures effective blocking of interference signals

5. The backlit LED display screen indicates the RF and AF signal strength, battery status, diversity channel indication (A/B), frequency, frequency group/channel, and other operating states

6. Adopting the latest developed "Audio Reference Compression Extension" patented technology, it has excellent dynamic response and excellent sound quality

7. True diversity wireless systems are designed specififically for touring and fifixed installation purposes, providing the highest reliability, sound quality, and transmission stability
