Features:
- The 4.3-inch TFT color display enables real-time monitoring of 8 channels, showing channel numbers, volume levels, operating frequencies, RF power, and audio waveforms. All settings can be easily adjusted via the responsive touch screen interface.
- Featuring true diversity reception technology, the receiver's intelligent CPU automatically selects the optimal antenna signal to ensure stable reception and prevent signal dropouts.
- A display lock function prevents accidental adjustments-once activated, channel and volume settings remain fixed to avoid unintended changes during operation.
- Equipped with a built-in feedback suppressor, the receiver allows users to enable or disable this function as needed to eliminate microphone howling.
- With a dedicated one-touch mute button, the system can instantly silence all 8 channels simultaneously for quick audio control.
- The receiver includes multiple preset frequency groups designed to avoid interference, significantly improving setup efficiency when operating multiple systems together.
- Four EQ modes are provided, including a customizable user mode that allows flexible adjustment of an 11-band equalizer for tailored sound in various acoustic environments.
- It offers extensive connectivity options: 8 antenna interfaces, 2 mixed unbalanced outputs, 2 mixed balanced outputs, and 8 balanced independent outputs.
- The host unit also features a one-touch mute function, capable of instantly muting all 8 channels at once.
- A host display lock function secures system settings-once engaged, channel and volume adjustments are disabled to prevent accidental changes.
- The microphone unit supports adjustable transmission power (high/low modes), allowing users to optimize battery life based on actual usage needs.
- The compact speaker unit includes a configurable auto-shutdown timer (1–8 hours). Once set, it automatically powers down during periods of inactivity, extending both battery life and overall product durability.
