Functions and 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 and wireless gain connection functions are available. The infrared automatic channel tracking and system locking functions ensure that any transmitter in this series can be paired with any receiver. This is particularly suitable for using multiple sets of products in the same location.
2. The display screen shows communication information. A large, clear, high-definition 2.5-inch LCD screen displays the wireless unit's battery power, 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, two-color design, with an external RF receiving signal light and an AF audio level indicator light for a clearer display of receiver operation. The silicone guide buttons provide a clean and organized display.
4. It uses a 6.3mm unbalanced output and an XLR balanced output for simultaneous output, facilitating connection to various audio processing devices.
5. Easily adjust the microphone volume with the left and right rotating VOLUME knob.
6. It has an [AFS] automatic search function to find clean, interference-free frequencies in the actual environment. Long-press SET to automatically search for and lock onto an interference-free channel in the actual working environment.
7. It has a manual frequency adjustment function. In the idle state, briefly press the ▲▼ buttons to adjust to the appropriate frequency point.
8. It has an [IR] infrared automatic frequency matching function. Briefly press the SET button. 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-type conference unit features a tabletop design and is 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 channel frequency, signal, battery power, and signal strength of the conference unit; dual-switch, dual-color indicator lights with 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 gooseneck microphone has a built-in 2-unit super-cardioid condenser microphone core, with a maximum sound pickup distance of 1.5 meters, and high-fidelity sound reproduction; the conference unit can be flexibly placed in the conference venue. The diversified conference system is suitable for various sizes of conference venues.
