Features:
True diversity receiver, Dual-channels independent frequency selection systems can minimize the frequency break occurrence.
Dual-channels independent frequency automatic search function can scan work environment where interference minimum frequency and locked quickly.
Through the IR infrared frequency technology, receiver and transmitter can synchronize the code with one key.
Professional performance level phase lock circuit, With noise lock squelch control and digital pilot technology when the transmitter is turned off, Pilot control silences the AF signal to suppress noise, while silencing the corresponding receiver.
Make sure it can impede the interference signal.
Backlit LED display indicates the work status for the strength of RF and AF signal, battery status, diversity channel indication (A / B), frequency, frequency group / channel.
Using "Audio Reference" patented technology has a good dynamic response of the sound quality.
True diversity wireless system is designed for touring and fixed installation purposes to provide the high reliability, sound quality and transmission stability.
Operating frequency: 640-690MHzMHz
Scope of Work: under typical conditions of 100 meters, outdoor 150 meters in straight line. In high power mode is 150 meters, outdoor 300 meters in straight line. Actual working range depends on RF signal absorption, reflection and interference.
Audio Frequency Response: 40 - 18,000 Hz, (+ 1 dB, -3 dB).
