The KMC9 professional UHF wireless microphone system is a high-performance wireless audio solution designed specifically for KTV rooms, stage performances, conference events, home entertainment, and other scenarios. Adopting mature and stable UHF ultra-high frequency transmission technology, coupled with a dual hand microphone design, it combines clear sound quality, stable signal transmission, and convenient operation experience, making it an audio device that balances professional performance and practicality.

Core Technologies & Performance Highlights

1. UHF Ultra-High Frequency Transmission Technology

Operating in the 640-690MHz UHF frequency band, it delivers stronger anti-

interference capability compared to traditional VHF bands. It can effectively avoid common environmental signal interference (such as crosstalk from mobile phones, WiFi, and other electronic devices), significantly reducing issues like frequency dropouts, noise, and unstable signals, and ensuring pure and continuous audio transmission.

2. Multi-Channel Design for Flexible Scenario Adaptation

The system is equipped with 2×100 selectable channels, supporting independent frequency selection for dual microphones. When multiple sets of devices are used simultaneously, interference-free channels can be switched quickly to easily avoid co-channel interference. It adapts to complex scenarios such as large-scale stages and simultaneous use in multiple venues, meeting the needs of parallel operation of multiple devices.

3. Automatic Infrared Frequency Pairing for Zero-Threshold Operation

Equipped with infrared synchronization and frequency pairing function, the microphones and receiver can automatically match channels with one click via infrared signals. No complex manual debugging is required, and pairing can be completed quickly upon power-up, greatly simplifying the installation and debugging process. Even beginners can use it easily, eliminating tedious frequency setting steps.

4. Stable 80-100 Meter Transmission Range

The optimized antenna reception and signal amplification design enables stable transmission over 80-100 meters in open environments. Whether in small-to-medium stages, KTV boxes, or conference rooms, it can fully cover the entire usage range, meeting the free movement needs of mobile singing, hosting, and other scenarios without being restricted by cables.

User-Friendly Design & Practical Functions

1. Multi-Function LCD Display

• Working channel number
• RF signal strength (signal quality at a glance, early prediction of weak signal areas)
• Audio input level (real-time volume monitoring to avoid feedback or insufficient volume)
• This allows full visibility of device status for more assured use and efficient maintenance.

2. Dual Handheld Microphone Configuration

• Two ergonomic handheld microphones with a comfortable grip that causes no fatigue even during prolonged use;
• The microphones are built with high-fidelity pickup capsules, delivering clear and delicate vocal reproduction with rich details, balancing the penetration required for singing and the clarity needed for speech;
• The microphone body integrates operation buttons with an orange label design, combining practicality and recognizability, and a UHF mark at the bottom for clear and intuitive brand and functional attributes.

3. Professional Receiver Design

• Metal body, sturdy and durable with stronger anti-interference capability, suitable for high-frequency use in professional scenarios;
• Dual external high-gain antennas provide wide signal reception range and strong stability, further improving anti-interference capability;
• The panel integrates a power switch, function buttons, and infrared receiving window with a clear layout for convenient operation.
