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 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 location.
2. The display screen shows communication information. The large and clear 2.5-inch high-definition LCD screen can display information such as the wireless unit's 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 external RF receiving signal light and an AF audio level indicator light for clearer display of the receiver's operation. It features all-silicone light guide keys for a clean 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-style conferencing 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 conferencing unit's channel frequency, signal, power, and signal strength; dual-switch dual-color indicator lights without 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 incorporates a dual-element supercardioid condenser microphone element with a maximum pickup range of 1.5 meters and high-fidelity original sound; the unit has an independent volume adjustment knob, allowing for flexible placement of the conferencing unit in the meeting. This versatile conferencing system is suitable for various sizes of meeting venues.
