Features:
1. Our company's UHF, 200-channel series wireless microphones use DPLL digital phase-locked loop multi-channel frequency synthesis technology and automatic noise control technology. Within a 50MHz frequency bandwidth at 250KHz intervals, it provides up to 200 channel selections. It offers 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. This is particularly suitable for multiple sets of products used in the same location.
2. The display screen shows communication information. The large, clear 2.5-inch HD LCD screen allows you to view information such as the wireless unit's battery level, frequency signal, signal strength, and audio level.
3. The frequency display screen changes color. The double-layer, dual-color process of the product's front panel, combined with the external RF receiving signal light and AF audio level indicator light, provides a clearer display of the receiver's operating status. The full silicone light guide keys provide a simple and neat display.
4. It adopts a 6.3mm unbalanced output and XLR cannon balanced output synchronous output design, facilitating 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 can display the conference unit's channel frequency, signal, power, and signal strength information. It features dual switches, dual-color indicator lights, and no mechanical button sounds. The conference unit has a charging port and supports direct power supply or battery charging. It comes standard with 3 1.5V batteries, with a battery capacity of 1200mAh. The microphone boom has a built-in 2-unit super-cardioid condenser microphone, with a maximum 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 in the meeting venue. A diversified conference system suitable for various large and small conference occasions.
