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 provides up to 200 channel selections. It offers lock control function selection, adjustable wireless gain connection function, and uses infrared automatic channel tracking and system locking functions. This ensures that any transmitter in this series can be paired with any receiver, especially suitable for using multiple sets of products in the same environment.
2. The display screen shows communication information. The large, clear, high-definition 2.5-inch LCD screen allows viewing of the wireless unit's battery power, frequency signal, signal strength, audio level, and other information statuses.
3. The frequency display screen changes color. The double-layer, dual-color process of the product's front panel, with an added external RF receiving signal light and AF audio level indicator light, clearly displays the receiver's operating status. The all-silicone light guide keys provide a simple and neat display.
4. It uses a 6.3mm unbalanced output and XLR cannon balanced output simultaneous 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 high-definition night crystal screen with high brightness, high contrast, wide viewing angle, and low power consumption. It displays the conference unit's channel frequency, signal, power, and signal strength information; dual switches and dual-color indicator lights, with no mechanical key 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 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 flexible placement of the conference unit in the meeting venue. This diversified conference system is suitable for various sized meeting venues.
