Features

Functional Features:
| Extensive Audio Output | Using 6.3 mm unbalanced output and XLR balanced output synchronization output design, convenient to connect all kinds of audio processing equipment |
|---|---|
| Ultra-Wide Carrier Frequency Band | Ultra-wide carrier frequency UHF 522MHz~936MHz, one-to-two antenna diversity reception, CPU intelligent selection, stable reception and long distance, providing users with a good application experience |
| PLL Phase Locked Oscillation Circuit | The stable PLL phase-locked oscillation circuit, combined with the “noise detection” mute control function, can effectively block the noise and radio frequency interference in the working environment. |
| Noise lock | Adopt noise locking and field strength locking double squelch locking circuit design, effectively prevent the radio frequency interference of other microphones, and improve the signal-to-noise ratio. |
| [AFS] Automatic Frequency Search | [AFS] Automatic frequency search function, after pressing the [AFS] button for 3 seconds, it will automatically search and lock to work on an interference-free frequency. |
| [IR] Infrared | With [IR] infrared automatic frequency matching function, as long as the [SYNC] button is pressed, the transmitter can automatically and accurately lock the working frequency of the receiver. |
