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 lock functions allow any transmitter in this series to be paired with any receiver. This is especially suitable for multiple sets of products used in the same environment.
2. The display screen shows communication information. A large, clear 2.5-inch LCD display shows 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 process, with an external RF receiving signal light and an AF audio level indicator light, providing a clearer display of the receiver's operation. It uses all-silicone guide light keys for a clean and neat display.
4. It uses a 6.3mm unbalanced output and XLR balanced output synchronous output design, facilitating connection to various audio processing equipment.
5. Easily adjust the microphone volume up or down using the left and right VOLUME rotary knobs.
6. It has an [AFS] automatic search function to find clean, interference-free frequencies in the actual environment. Pressing and holding SET will automatically search for and lock onto a channel in the actual operating environment that is free from interference.
7. It has a manual frequency adjustment function. Briefly press the ▲▼ buttons when there is no operation to adjust to the appropriate frequency point.
8. It has an [IR] infrared automatic frequency matching function. Simply press the SET button briefly. When the display screen flashes IR, align the IR lights of the transmitter and receiver to automatically lock the transmitter to the receiver's operating frequency point. 9. The base-style meeting 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 meeting unit's channel frequency, signal, power, and signal strength information. Dual switches and dual-color indicator lights eliminate mechanical button sounds. The meeting 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 has a built-in 2-unit hypercardioid condenser microphone, with a maximum pickup distance of 1.5 meters and high-fidelity original sound. The meeting unit can be flexibly placed in the meeting venue. This versatile meeting system is suitable for various large and small meeting occasions.
