• Product range： BM-922R Respective category： UHF ------Product detailed parameter FUNCTION: 1. Using UHF 700-870 MHz band to avert interferencing frequency. 2. Dual channel designed,two microphones can use at the same time to sing without any disturbing caused by. 3. Microprocessor control, that's easy to operation 4. All using quartz crystal oscillating circuits,so the frequency is very steady. 5. Using the latest SAW filter of the RF,to avoid those interferencing signal from band outside 6. Using twice mixer high-frequency circuit design,it has very high sensitivity. about 3 uV 7. Multilevel quiet control circuit,to avoid interference signal from outside open the mute system 8. Special design companding circuit,strongly improve s\n ratio 9. Special voice compress-limiter design,it will not crack though the singer sang very loudly. 10. Using excellent dynamic cardioid direct cartridge,the timbre bright and clear. 11. Choose high quality component,accurate rational circuit design,reliability is enhance 12. All using SMT ,print circuit board design tightness and credibility 13. high efficiency batteries consumption design, so the handheld could be in using for 20 hours continuously.(AAA batteries) 14. Using high gain antenna,the space availability is more than 100 meters at the clearing . 15. All ready output and input socket,it will be more convenience to connect every equipment. 16. Exquisite streamline aspect ,make holding more comfortable. 17. It is suitable for small and large stages, ballrooms,auditoria, classrooms and families RECEIVER : * POWER SUPPLY: DC 17V * CONSUME POWER: 4 WATER * SIGNAL/NOISE RATIO: MORE THAN 90DB * IMAGE & SPURIOUS REJECTION:MORE THAN 80db * BORDER UPON CHANNEL REJECTION:MORE THAN 80db * RECEIVING SENSITIVTY: 10dBuV(SINAD=30dB) * DE-EMPHASIS: 50us HANDING MICROPHONE: * TRANSMITTER POWER: 8.5mW * MODULATION TYPE : FM,F3F * MAX DEVIATION: ±25Khz * SPURIOUS EMISSION:MORE THAN 40dB(WITH CARRIER) * BATTERY VOLTAGE: 1.5Vx2 * CONTINOUS USING: 20hours COMPREHENSIVE PERFORMANCE: * COMPREHENSIVE PERFORMANCE * CARRIER FREQUENCY: UHF850MHz * FREQUENCY STABILIZATION LESS THAN±30ppm * DYNAMIC RANGE: MORE THAN 90dB * TOTAL HARMONIC DISTORTION: LESS THAN 0.5% * FREQUENCY RESPONSE: 40HZ-15KHZ±3dB * AUDIO OUTPUT LEVEL: SEPARATE TYPE:0--±400mV MIX TYPE: 0--±200mV
