True Diversity Dual-Channel and Lavalier Microphone TK-612UH (Lavalier)

A professional wireless microphone solution designed for stable voice transmission, flexible frequency management, and reliable audio performance. The system combines digital signal processing, PLL frequency synthesis, intelligent monitoring, and multiple audio output interfaces for applications requiring dependable wireless voice pickup.

Key Features

Digital Security & Signal Processing

• Uses a digital pilot signal with a 2048-bit symmetric encryption algorithm to help protect wireless audio transmission against unauthorized interception.

• Integrates PLL (Phase-Locked Loop) frequency synthesis technology for accurate and stable RF frequency generation.

• Dynamic audio compression and an automatic level control circuit help maintain consistent audio output across different speaking volumes.

• Noise Lock and Noise Control functions help suppress unwanted background interference.

• Audio code navigation is integrated with the noise-lock control system for improved signal management.

Intelligent Frequency Management

• One-touch automatic frequency scanning allows users to quickly locate an available operating channel.

• Intelligent digital signal field-strength detection helps identify RF signal conditions.

• Fixed-point frequency monitoring continuously checks the selected frequency during operation.

• Receiver and transmitter power status can be monitored during use.

• Smart battery monitoring provides a low-voltage warning to help prevent unexpected microphone shutdown.

Receiver Design

• The receiver host includes a built-in key lock function to help prevent accidental operation or setting changes.

• Provides independent XLR balanced audio output for professional audio equipment.

• A 6.3mm unbalanced hybrid output is also available for connection to compatible audio devices.

• One receiver supports two lavalier microphones, providing a convenient configuration for two-speaker applications.
