Advanced Wireless Conference Microphone1/4

Product Description:The product uses a super-directional high-capacitance microphone capsule, offering excellent sound quality and frequency response. It features a lock-type robust detachable structure, ensuring highly reliable stability. The independently designed new base makes it ideal for high-end conference projects. Broad frequency response, clear and transparent sound, low noise, and extra-long microphone ON/OFF lifespan. When the microphone is turned on, the red indicator light on the capsule illuminates. The goose-neck and base are separable, suitable for large, medium, and small conferences, public communication, teaching, and lectures. ID code identification prevents interference from external sources.Main Features:* Uses UHF 640~830MHz frequency band, employing PLL frequency synthesis technology; frequencies are adjustable. Up to 5 units can be used simultaneously without interference.* Centralized control with an integrated CPU and digital LCD interface for convenient operation and outstanding performance.* Multi-stage narrowband high-frequency and intermediate-frequency filtering to effectively eliminate interference signals.* Audio compression-expansion technology significantly reduces noise and increases dynamic range.* The receiver uses multi-stage high-frequency amplification for high sensitivity.* Ideal usage distance is 80 meters.Conference Microphone Receiver Specifications:Operating Frequency: 640~830MHz (adjustable as needed)DC Input Voltage: DC12V 1200mAOscillation Mode: Dual phase-locked frequency synthesis (PLL)Tuning Method: FMMaximum Frequency Deviation: ±50KHzFrequency Response: 60Hz～18000HzSignal-to-Noise Ratio: ≥89dBLow-Frequency Attenuation: 125Hz 6dBOutput Impedance: 250ΩMaximum Sound Pressure: 135dB SPL 1KHz at 1% T.H.DDynamic Range: ≥105dBS/N Ratio: >98dBT.H.D Distortion: <0.5%T2 Conference Microphone Specifications:Polar Pattern: Capacitive unidirectionalPower Supply: 2 AA batteries, 3VWorking Current: Standby ≤110mA, Talking ≤180mASensitivity: -40dB±2dBModulation Method: FMOscillation Mode: PLLDisplay: 2.8-inch screenFrequency Range: 640MHz --830MHz (adjustable as needed)Bandwidth: 30MHzOutput Power: 20mWWorking Duration: 8-10 hoursBattery Consumption: <200mAMaximum Modulation: 60KRadiated Power: ≤ 9dBmReference Speaking Distance: 10cm--50cmOperating Temperature: -10℃ --45℃Frequency Deviation: <0.002Base Dimensions: 111*137*55mmGooseneck Length: 220mmWeight: 1.5kg
