Features:
1. Our company's UHF, 200-channel series wireless microphones utilize DPLL digital phase-locked loop multi-channel frequency synthesis technology and automatic noise control technology. Within a 50MHz frequency bandwidth, with 250KHz intervals, it offers up to 200 channel selections. It features lock 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 pair with any receiver. This is particularly suitable for using multiple sets of products in the same location.
2. The display screen shows communication information. The large, clear, high-definition 2.5-inch LCD screen allows you to view information such as wireless unit 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 an AF audio level indicator light for a clearer display of the receiver's operation. It has full silicone guide keys, and the display is simple and neat.
4. It adopts a 6.3mm unbalanced output and XLR cannon balanced output synchronous output design for easy connection to various audio processing equipment.
5. The base-type conferencing unit features a tabletop design and is equipped with a 2-inch high-definition 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 conferencing unit; dual switches with dual-color indicator lights, no mechanical key sounds; the conferencing unit has a charging port and supports direct power supply or battery charging; it comes standard with 3 1.5V batteries with a capacity of 1200mAh; the microphone boom has a built-in 2-unit hypercardioid condenser microphone element, with a maximum pickup range of 1.5 meters, high-fidelity original sound; the unit has an independent volume adjustment knob, allowing for flexible placement of the conferencing unit at the meeting site. This diversified conferencing system is suitable for various sizes of meeting venues.
