Features:
1. Our company's UHF, 200-channel series wireless microphones utilize DPLL digital phase-locked loop multi-channel frequency synthesis technology and noise automatic control technology. Within a 50MHz frequency bandwidth, with 250KHz intervals, it provides up to 200 channel selections. It offers lockable control function selection, adjustable wireless gain connection function, and utilizes infrared automatic channel tracking and system lock 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 location.
2. The display screen shows communication information. A large and clear 2.5-inch HD LCD screen displays the wireless unit's battery level, frequency signal, signal strength, audio level, and other status information.
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 clearer display of the receiver's operation. It features full silicone guide light keys for a clean and neat display.
4. It uses a 6.3mm unbalanced output and an XLR cannon balanced output synchronous output design for easy connection to various audio processing devices.
5. The base-type conference unit features a table-top 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 conference unit's channel frequency, signal, battery level, and signal strength; dual-switch dual-color indicator lights with no mechanical button sound; 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 for flexible placement of the conference unit at the meeting site. This diversified conference system is suitable for various sizes of conference venues.
