Product Description
- Utilizing pure automatic frequency selection (true diversity) reception mode, not only does it have a long reception range, but each independent channel also features individual encryption with strong anti-interference capability, eliminating cross-frequency issues.
- Equipped with dual antennas and dual receiving circuits for true diversity reception, the system adopts a new, faster single-channel digital automatic frequency selection long-range microphone.
- The receiver features automatic scanning for clear frequencies, a panel function lock for secure operation, and independent adjustable channels with up to 2,280 frequencies per channel.
- LCD display shows standby status in orange and active status in white. Functions include automatic frequency selection signal, channel, frequency, transmitter battery level, reception sensitivity, mute threshold, and more.
- Unique CPU-controlled power on/off ensures no popping sound during startup or shutdown, regardless of the transmitter or receiver's state.
- Professional double-conversion and multi-stage RF filtering technology allow multiple systems to operate simultaneously without interference. Triple noise cancellation (tone code, RF strength, noise detection) effectively blocks disturbances.
- The transmitter's lock mode prevents accidental shutdown when enabled, and it features an OLED display.
- The system employs the most stable phase-locked loop (PLL) synthesizer tuner, effectively blocking noisy RF interference in the environment.
