True diversity receiving system, the system has excellent anti-interference performance and strong signal receiving ability.
Fully automatic frequency search operation, effectively locking the cleanest frequency in the working environment, and strong practicability.
The LED display indicates the system volume, battery power, diversity channel A/B switching display, working frequency and channel, receiving distance gear, system lock key, etc.
Receiving distance HI/MD/LOW three gears adjustable.
Professional performance level phase locking circuit, with noise locking squelch control and digital pilot frequency technology. When the transmitter is turned off, the pilot frequency control will mute the AF signal to suppress the noise, and at the same time mute the corresponding receiver to ensure the effective blocking of interference signals.
Display screen will turn to red alarm when the battery of the transmitter is low, which effectively prompts the operation.
Each channel has 3*10 bit LED light indicating A/B RF signal strength and level signal strength, the working state is clear and visible.
The system adopts electronic volume control, higher precision and controllable, eliminate the resistance noise of the potentiometer.
PLL phase-locked loop frequency synthesis technology.
Working frequency :640~690MHz, controlled by microcomputer CPU.
