True Diversity Dual-Channel and headset microphone TK-612UH (Head-worn)

This digital wireless microphone system is designed for reliable voice transmission and convenient frequency management. It combines digital signal processing, encryption, automatic frequency control, noise management, and power monitoring in one wireless audio solution.

Main Features

1. Digital Signal Encryption
   Uses a 2048-bit symmetric encryption algorithm to help protect wireless audio transmission against unauthorized eavesdropping.

2. PLL Frequency Synthesis
   Incorporates PLL (Phase-Locked Loop) frequency synthesis technology together with dynamic audio compression and automatic level control for stable audio output.

3. Transmitter and Receiver Power Monitoring
   Monitors the operating power status of the wireless transmitter and receiver.

4. Low-Battery Warning
   Provides an intelligent battery-level warning to indicate low-voltage conditions during operation.

5. Automatic Frequency Search
   Supports one-touch automatic frequency scanning, digital RF field-strength detection, and fixed-point frequency status monitoring during use.

6. Host Lock Function
   The receiver host includes a built-in key-lock function to help prevent unintended setting changes.

7. Multiple Audio Output Interfaces
   Equipped with XLR balanced independent outputs and 6.3 mm unbalanced hybrid outputs for flexible audio system connection.

8. Noise Lock and Audio Control
   Features Noise Lock, Noise Control, and Audio Code Navigation functions for improved wireless audio management and noise control.

9. Dual Head-Mounted Microphone Configuration
   One receiving host can be paired with two head-mounted microphones.
