Features:
1. Our company's UHF, 200-channel series wireless microphones use DPLL digital phase-locked loop multi-channel frequency synthesis technology and noise automatic control technology. Within a 50MHz frequency bandwidth, at 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. This is especially suitable for using multiple sets of products in the same place.
2. The display screen shows communication information. A large, clear 2.5-inch LCD screen displays the wireless unit's battery power, frequency signal, signal strength, audio level, and other information.
3. The frequency display screen changes color. The product's front panel uses a double-layer, dual-color process, with an added external RF receiving signal light and an AF audio level indicator light, which clearly displays the receiver's operating status. The full silicone light guide buttons provide a clean and neat display.
4. It uses a 6.3mm unbalanced output and XLR cannon balanced output synchronous output design, making it easy to connect to various audio processing devices.
5. The base-style conference unit has a table-top design, equipped with a 2-inch high-definition 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. It has dual switches and dual-color indicator lights, without mechanical button noise. The conference unit has a charging port and supports direct power supply or battery charging. It comes standard with 2 1.5V batteries, with a battery capacity of 1200mAh. The gooseneck microphone has a built-in 2-unit hypercardioid condenser microphone element, with a maximum sound pickup distance of 1.5 meters and high-fidelity original sound. The unit has an independent volume adjustment knob, allowing for flexible placement of the conference unit at the meeting site. This versatile conference system is suitable for various sized meeting occasions.
