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 at 250KHz intervals, it provides up to 200 channel selections. Lock control function selection, adjustable wireless gain connection function, and infrared automatic channel tracking and system locking functions 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 HD LCD screen displays information such as the wireless unit's battery power, frequency signal, signal strength, and audio level.
3. Color-changing pairing display screen. The product's front panel features a double-layer, dual-color process, with an external RF receiving signal light and an AF audio level indicator light for clearer display of receiver operation. The silicone-guided keys provide a clean and organized display.
4. Utilizing a design with simultaneous 6.3mm unbalanced output and XLR balanced output, it facilitates 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 that offers 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. The dual-switch dual-color indicator lights operate silently, and the conferencing unit has a charging port, supporting direct power supply or battery charging. It comes standard with 2 1.5V batteries, with a battery capacity of 1200mAh. The boom microphone incorporates two ultra-cardioid condenser microphone elements, providing a maximum pickup distance of 1.5 meters with high-fidelity sound. The unit has an independent volume adjustment knob, allowing for flexible placement in conference settings. This diversified conferencing system is suitable for conferences of all sizes.
