True diversity one drag four hand-held microphones Product parameters

Function introduction: 1. UHF ultra-high frequency band is used, which has less interference and reliable transmission than the traditional VHF frequency band. 2. Advanced digital ID pilot technology is used to completely eliminate the phenomenon of cross-frequency. 3. Advanced 248-bit symmetric encryption algorithm is used for wireless signal, which prevents eavesdropping. 4. Diversity reception technology is used, the receiving distance is farther and more stable, and the effective using distance is 500 meters. 5. Intelligent wireless signal field strength FI detection, real-time monitoring of the interference status of the frequency. 6. It has the function of one-key automatic search of clean frequency points, one-key lock key function, and infrared frequency matching function. 7. 0-level electronic volume control is used, which is concise and accurate, 200 groups of optional frequencies, and the microphone is optional and universal. 8. The consumption of the receiver and the transmitter is displayed synchronously, and the battery is automatically turned off when the low voltage of 1.8V blinks. 9. The design has the function of feedback howling suppression and weakening, which can effectively reduce feedback howling. 10. The microphone has a high-strength anti-mobile phone wave interference design, which can eliminate mobile phone interference noise. 11. Good sound quality, high sound fidelity, suitable for large and small stage performances, large and small conference, multi-function halls, etc. Receiver parameters: Host working voltage: DC-12V Working current: 1000mA Cons: 12W Display: LCD*2 RF carrier frequency range: 610-690MHZ Working distance: 500 meters without System: FM Pilot mode: Digital pilot Maximum number of channels: 520 System compatibility: 12 used at the same time Frequency: 80HZ - 15KHz (±3db) Dynamic range: > 110db System distortion/total harmonic distortionD: < 0.5% Signal-to-noise ratio: S/N> 105db (A) RF sensitivity:100dbm for 30db S/N Ratio Image suppression: > 75db Output interface: (XLRx2)/(1/-inch connector×1) Audio output level: (XLR: 10dbV) / (1/4-inch connector: 8dbV) impedance: (XLR:3KΩ) / (1/4-inch connector:3KΩ) Display mode: LCDx2 Power requirement: 1V/1A Working temperature range: -15-50 ℃ Receiving sensitivity: -105dBM diversity reception Distortion THD:lt;0.01% Audio output voltage: 0.3V Adjacent channel interference suppression: >60dB Waist- transmitter headworn microphone/lapel microphone parameters: Type of pickup: Condenser Microphone core directivity: Cardioid Pick-up sensitivity: &;-20dBM (1V) Transmission power: > 20dBM(10mWH) Microphone consumption: 15mA Effective distance: 500 meters in a straight line without obstacles Audio response: 50HZ—18KHZ Frequency stability -0.001% Anti-mobile phone electromagnetic wave: Yes Gain: 10db Input impedance: 5KΩ RF output: 110mW Image suppression: > 50db Pilot: Digital pilot Display mode: LCD Power requirement: 1.V*2(AA) Battery life: > 5 hours/ calculated by 1800mA Frequency stability: ±0.00% Communication command: Microcomputer CPU control is used Battery warning: Intelligent battery under-voltage warning display Circuit index: PLL frequency synthesis technology dynamic compression and automatic level control circuit
