S-7002 Professional One to Two True Diversity Wireless Handheld Microphone

Using a four antenna combination dual channel single receiving system, we have independently developed a unique high-sensitivity diversity selection circuit with excellent anti-interference performance and strong signal reception capability, which can minimize the occurrence of frequency interruptions;

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

A professional performance level phase locking circuit, combined with noise locking mute control and digital pilot technology, when the transmitter is turned off, the pilot control silences the AF signal to suppress noise and also silences the corresponding receiver. Ensure effective blocking of interference signals;

Backlit LED display screen indicates RF and AF signal strength, battery status, diversity channel indication (A/B), frequency, frequency group/channel and other working status;

SQ has an adjustable receiving distance of -65~-100dBm and an operation lock function to prevent accidental operation;

● Has high dynamic response, wide frequency response, eliminates noise caused by high frequencies, and achieves excellent sound quality;

Self developed core technology “VCO and RF circuit” enables larger available bandwidth and more stable signal reception.
