One to two professional KTV/private room wireless microphone

SKM5555U

Functional features:

1. The UHF and 200 channel series wireless microphones produced by our company adopt DPLL digital phase-locked loop multi-channel frequency synthesis technology and noise automatic control technology. They provide up to 200 channel options at a frequency bandwidth of 50MHz and 250KHz intervals, with lockable control function options and adjustable wireless profit connection function, By utilizing the infrared automatic channel tracking and system locking functions, any transmitter and receiver in this series can be tuned up, making it particularly suitable for multiple products to be used in the same situation.

2. The display screen displays communication information, and the wide and clear high-definition 2.5ft LCD screen can view the battery level, frequency signal, signal strength, and audio power status of the wireless unit.

3. The color change of the frequency display screen, the double-layer dual color process on the front panel of the product, and the addition of an external RF receiving signal light and AF audio level indicator light, clearer display of the receiver's work content, all silicone light guide buttons, and simple and neat display.

4. Adopting a 6.3mm unbalanced output and XLR XLR balanced output synchronous output design, it is convenient to connect various audio processing devices.
