True Diversity Dual-Channel and headset microphone TK-712UG (Headset)

This professional wireless microphone system is designed for reliable audio transmission in stage performances, conferences, broadcasting, education, and professional sound reinforcement environments.

The system integrates intelligent frequency scanning, automatic channel selection, infrared synchronization, adjustable transmission power, audio gain control, and advanced anti-interference technologies to provide stable wireless communication and high-quality audio performance.

With a wide frequency range, multiple channel options, real-time spectrum monitoring, and flexible audio adjustment functions, this system enables efficient frequency management and dependable operation in complex RF environments.

Key Features

Intelligent Frequency Management

• Spectrum Scanning:
  The system scans the current frequency environment and displays frequency usage through a visual spectrum interface, helping users identify available clean frequency points.

• Automatic Frequency Selection:
  Automatically detects and selects suitable interference-free frequency points for quick setup.

• Manual Frequency Selection:
  Users can manually adjust operating frequencies through the function keys according to application requirements.

• Channel Number Setting:
  The channel number corresponding to the host can be configured. After infrared pairing, the transmitter and receiver display the same channel number to establish a matching connection.

Wireless Transmission Control

• Adjustable Transmission Power:
  The transmitter supports four output power levels: low, medium, high, and ultra-high, allowing users to optimize transmission distance and operating stability.

• Audio Gain Adjustment:
  The transmitter audio gain can be adjusted within the range of -18dB to -27dB to match different input signal requirements.

• Infrared Pairing Function:
  Infrared synchronization enables the transmitter and receiver to exchange and synchronize internal data automatically.

Receiver Sensitivity and Signal Management

The receiver sensitivity can be adjusted from -77dB to -110dB.

Higher sensitivity settings help extend transmission distance, while lower sensitivity settings improve resistance to interference in crowded RF environments.

The receiver supports multiple pilot and ID verification modes:

• Real-Time ID Mode: Continuously verifies ID information for each data packet to provide maximum anti-interference capability.

• Single-Time ID Mode: Performs ID verification only during the connection process.

• ID Disabled Mode: Detects pilot signals without ID verification.

• Pilot Disabled Mode: Measures signal strength without detecting ID or pilot information.

The system is compatible with FM-modulated microphones from other brands operating at the same frequency.

Audio Processing Functions

• 15-band equalizer adjustment for precise audio curve control

• 9 built-in reverb modes for different sound applications

• 5 built-in feedback suppression modes to reduce microphone whistling

• Integrated frequency spectrum analyzer for real-time monitoring of frequency usage

• USB interface for software upgrades through USB flash drives
