Description

The main function: Use UHF700-870MHz frequency band to avoid interference frequency Fully automatic microphone working channel scanning Automatically does not interfere with channel scanning Full information LCD display for high frequency intensity, audio dynamics, channel frequency, etc. Dual microphone design, can sing at the same time Handheld microphone invisible antenna, beautiful and practical Adopt true diversity receiving circuit design to ensure continuous speed within the effective distance and eliminate dead angle A new high-frequency surface acoustic filter is used to filter out out-of-band interference signals High frequency circuit design with secondary frequency conversion, high sensitivity, about 3uV Multiple squelch control circuit, reject external interference and turn on the local squelch system Specially designed voice compression and expansion circuit to greatly improve signal to noise ratio Voice compressor design, the singer will not sing when cracking Use a moving coil heart-shaped pointing head for clear and bright sound Select professional parts, reasonable circuit design, and greatly improve reliability Efficient battery power design allows the microphone to last for 20 hours (AAA battery) Use high-gain antennas to effectively open up to 100 meters Input and output interface for easy connection to various devices Beautiful streamlined appearance for comfort Standard 19-inch mounting size Dedicated to stage and KTV requirements       Fixed receiver: Use the power supply voltage: AC220V/45-60HZ Adapter output voltage: DC18V Power consumption: 5WATER Signal to noise ratio: 〉98dB False interference ratio: 〉80dB Adjacent channel interference ratio: 〉80dB Receive sensitivity: 〉5dBu(SINAD=20dB) To increase: 50uS       Handheld microphone: Transmit power: 20mW Modulation method: FM, F3F   Modulation: ±40KHZ Higher harmonics: less than 40DB above the main wave reference Use the power supply voltage: 3V (2 1.5V alkaline batteries) Continuous use time: 20 hours       Comprehensive performance: Carrier frequency: UHF700-870MHz Frequency stability: <±30ppm Dynamic range: 〉90dB Harmonic distortion: < 0.5% Frequency response: 40HZ ~ 15KHZ ± 3dB Audio output: Stand-alone: ​​:0~±400mV Mixed type: 0 ~ ± 200mV
