●The digital LCD display clearly shows the real-time working status of the receiver and transmitter; ●Using professional-grade audio compression-expansion technology, low noise, small tail, and larger dynamic range ●Applying PLL radio frequency stabilization technology, accurate frequency, stable and reliable work ●With independent output (XLR) and mixed (q6.3mm) output, it is convenient to connect audio processing and power amplifier equipment ●Infrared framing, the transmitter can be interchanged, the operation is simple, and the function is advanced ●Two choices of output ports, balanced and unbalanced, to adapt to different device connection requirements; ●Superior anti-interference ability, can effectively suppress noise interference and co-frequency interference brought by the outside. The intermediate frequency is rich, and the sound is magnetic and thick, which is the essence of the sound quality of the vocal microphone. technical parameter Number of receiver channels: eight channels Receiving method: CPU control automatic selection Receiving frequency oscillation mode: PLL phase-locked loop loop Carrier frequency band: UHF 640-690MHz (The usable frequency depends on local regulations) Frequency pairing: -Key infrared pairing setting Frequency stability: s +0.005% (-10~609 Dynamic range: 100dB Maximum frequency deviation: +45KHz Sensitivity: 12dBuV (80dBS/N) Function display mode: digital LCD display technical parameter: Sound head: dynamic handheld microphone (optional) Condenser: Gooseneck conference microphone/lavalier microphone/head-mounted microphone (optional) Frequency oscillation mode: PLL phase-locked loop loop Carrier frequency band: UHF 640-690MHz (the usable frequency depends on local regulations) Bandwidth: 50MHz RF output: 10mW False interference ratio: <-50 dBC Image rejection: 50dB Modulation frequency deviation: 25Hz Discrete suppression: .60dB OLED display: channel, frequency, battery display Channel conversion method: automatic frequency Battery type: AA alkaline batteries x2 Battery life: Approximately 8 hours at 30mW
