This is a single-channel true diversity super long-range wireless microphone. The true diversity receiving method is more stable, with automatic selection to eliminate dead spots and avoid frequency interruption. This microphone adopts a new type of anti-vibration design to achieve excellent low touch noise performance, lower popping sensitivity, and the acoustic transparency of a fixed polarized capacitor microphone, which can transmit "completely uncompressed, artifact-free, and good dynamic range audio." It is designed for harsh wireless environments and uses digital audio DSP encoding and decoding technology to transmit high-quality audio. The HD mode transmission has no compression or coloration, and the sound quality is comparable to wired microphones. The host also has a monitoring function to monitor the transmitting end in real-time, making the performance reliable. With its exquisite appearance, convenient operation, and shocking price, it wins market competitive advantages with superior professional quality. The receiving distance is up to 1000 meters, suitable for occasions with long-distance requirements, such as schools and large outdoor events.
 
Product Features:
◆ Uses an international EIA standard 1U 1/2 metal chassis, combined with a novel and simple LCD display, showing elegance.
◆ Uses the latest encryption technology to communicate in the ultra-high frequency band, and uses the latest 5G fast audio signal transmission: 10Gbit/s, no-delay transmission, solves the delay caused by distance, and achieves instant transmission.
◆ Ultra-wideband UHF630MHz~690MH, automatic selection, true diversity reception of single-channel receiving circuit.
◆ The true diversity receiving system uses two identical channel receiving circuits to reduce noise and sound leakage caused by radio frequency interference.
◆ Adopts noise lock and field strength lock dual squelch lock circuit design, which effectively prevents radio frequency interference from other microphones and improves the signal-to-noise ratio.
◆ Adopts 6.3mm unbalanced output and XLR balanced output synchronous output design, which is convenient for connecting various audio processing equipment.
◆ The receiver's bright LCD display can show the working channel or frequency, RF, and built-in electronic volume.
◆ With electronic volume adjustment, rotate the VOLUME knob left and right when there is no operation to easily adjust the microphone volume.
◆ With headphone monitoring output and monitoring volume adjustment.
◆ Has [AFS] automatic search function for clean, interference-free frequencies in the actual environment. Short press SCAN to automatically search and lock on interference-free channels in the actual working environment.
◆ Has a frequency lock function. Long press the SCAN button to realize the switch of the frequency lock function.
◆ Has a manual frequency modulation function. Short press the VOLUME knob when there is no operation, and rotate the button left and right to adjust to the appropriate frequency point.
◆ With [IR] infrared automatic frequency pairing function, as long as you short press the SET button, when the display flashes IR, point the transmitter and receiver's IR lights face to face, the transmitter can automatically and accurately lock the receiver's working frequency point.
◆ The stable DSP chip frequency lock circuit, combined with the "digital pilot" mute control function and the "noise detection" mute control function, can effectively block noisy radio frequency interference from computer equipment, karaoke machines, and DVDs in the working environment.
◆ The handheld microphone has a novel appearance design and uses a new technology OLED LCD display, which can display the working frequency. The tube body is made of sturdy and durable all-alloy material, which effectively protects the built-in circuit board components and battery holder, and has an ergonomic grip.
◆ Precise low-consumption circuit design, using 1 18650/3.7V lithium battery, the battery life is up to 5 years.
◆ Handheld supports Type-C charging port direct power supply.
◆ Can be used with wireless handheld microphones and wireless bodypack transmitters.
