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, at 250KHz intervals, it provides up to 200 channel selections. It offers lockable control function selection and adjustable wireless gain connection function. Using infrared automatic channel tracking and system locking functions, any transmitter in this series can be paired with any receiver, especially suitable for multiple sets of products used in the same place.
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, etc.
3. 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, displaying the receiver's operation more clearly. Silicone guide buttons provide a simple 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. Base-style conference unit with a tabletop design, equipped with a 2-inch high-definition night crystal screen. It features high brightness, high contrast, wide viewing angle, and low power consumption. It displays the conference unit's channel frequency, signal, power, and signal strength. Dual switches with dual-color indicator lights produce no mechanical button 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 capacity of 1200mAh. The boom microphone has a built-in 2-unit super-cardioid condenser microphone core, with a maximum pickup distance of 1.5 meters, providing high-fidelity original sound. The unit has an independent volume adjustment knob. Conference units can be flexibly placed in meeting venues. The diversified conference system is suitable for various conference occasions of all sizes.
