Features:
1. Our company's UHF, 200-channel series wireless microphones adopt DPLL digital phase-locked loop multi-channel frequency synthesis technology and automatic noise control technology. Within a 50MHz frequency bandwidth, with 250KHz intervals, it provides up to 200 channel selections. It has lockable control function selection, adjustable wireless gain connection function, and uses infrared automatic channel tracking and system locking functions to ensure that any transmitter in this series can be paired with any receiver, especially suitable for multiple sets of products used in the same place.
2. The display screen shows communication information. The large and clear 2.5-inch HD LCD screen displays information such as the wireless unit's battery power, frequency signal, signal strength, and audio level.
3. The frequency display screen changes color. The product's front panel features a double-layer, dual-color design, with an added external RF receiving signal light and AF audio level indicator light, providing a clearer display of the receiver's operating status. The silicone guide keys provide a simple and neat display.
4. It adopts a 6.3mm unbalanced output and XLR cannon balanced output synchronous output design for easy connection to various audio processing devices.
5. The base-type conference unit features a tabletop design, equipped with a 2-inch HD night crystal screen with high brightness, high contrast, wide viewing angle, and low power consumption. It displays the channel frequency, signal, power, and signal strength of the conference unit; dual-switch dual-color indicator lights without mechanical key sounds; the conference unit has a charging port and supports direct power supply or battery charging; standard configuration of 3 1.5V batteries, with a battery capacity of 1200mAh; the microphone rod has a built-in 2-unit super-cardioid condenser microphone core, with a maximum sound pickup distance of 1.5 meters, and high-fidelity original sound; the unit has an independent volume adjustment knob, allowing flexible placement of the conference unit at the meeting site. A diversified conference system suitable for various large and small meeting occasions.
