Features:
1. Our company's UHF, 200-channel series wireless microphones use DPLL digital phase-locked loop multi-channel frequency synthesis technology and noise automatic control technology. Within the 50MHz frequency bandwidth, with a 250KHz interval, it provides up to 200 channel selections. Lock control function selection and wireless gain connection function are adjustable. Using infrared automatic channel tracking and system locking functions, 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. A large and clear 2.5-inch HD LCD screen allows you to view the wireless unit's battery power, frequency signal, signal strength, audio level, and other information.
3. The frequency display screen changes color. The product's front panel uses a double-layer, dual-color process and includes an external RF receiving signal light and an AF audio level indicator light, which more clearly displays the receiver's operation. It features all-silicone guide light keys, and the display is simple and neat.
4. It uses a 6.3mm unbalanced output and XLR cannon balanced output synchronous output design, making it easy to connect to various audio processing devices.
5. It has an electronic volume control function. In the idle state, a short press of the ▲▼ buttons easily adjusts the microphone volume.
6. It has an [AFS] automatic search function that finds clean, interference-free frequencies in the actual environment. A long press of SET will 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, a long press of the ▲▼ buttons adjusts 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 transmitter's and receiver's IR lights, and the transmitter will automatically and precisely lock onto the receiver's operating frequency point.
9. The base-type conference unit has a table-top 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 can display the channel frequency, signal, power, and signal strength of the conference unit; dual switches and dual-color indicator lights; no mechanical key 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 battery 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 unit has an independent volume adjustment knob, allowing for flexible placement of the conference unit at the meeting site. A diversified conference system suitable for various sizes of conference venues.
