Carlirad Lavalier Microphone System Compatible with Iphone Android

UHF wireless transmission, providing high-fidelity sound source; real-time noise reduction, the noise brought by the environment in the future when recording is suppressed as much as possible to ensure that the required sound has a higher signal-to-noise ratioWidely compatible with smart phones, digital SLR cameras, camcorders, voice recorders, and personal computersDSP digital audio companding reduces the noise in the wireless transmission system to a minimum. 16 switchable frequency points to realize operation without environmental interference; (the number of channels corresponding to different frequency bands in different countries may vary)The volume of the receiver and transmitter can be adjusted arbitrarily to adapt to the volume level of different equipment; with a variety of working indicators, such as receiver RF, AF;transmitter AF, PK, low battery indicator, etc., can display the various working status of the product in real timeSystem technical indicators: RF carrier frequency range: 470MHz~960MHz; Frequency stability: 0.005%; Effective working distance (Perfect environment): greater or equal to 50m; Audio companding: DSP digital audio companding; Audio frequency response: 50Hz~1800Hz +/- 3dB; Dynamic range: 92 dB; Signal-to-noise ratio (A weighting): 105 dB; Total harmonic distortion: less than or equal to 0.8%, @1KHz; Operating temperature range: -10 ~ +50Receiver technical indicators: Receiving bandwidth: 470MHz~960MHz; Receiving method: superheterodyneImage rejection: 45dBm; RF sensitivity: when input 10dBu, S/N greater or equal to 45dBSquelch adjustment: built-in setting parameters; Frequency synchronization method: manual button settingMaximum output level: LINE 0.72Vpp; Output level adjustment range: 4 levels adjustable, attenuation adjustment, every 3dB stepPower supply mode: 2 x AA 1.5V (without batteries); Normal working current: 3V 100mA; Battery life: greater or equal to 11 hoursLaunch technical indicators:Carrier bandwidth: 470MHz~960MHz; Oscillation mode: PLL frequency synthesisTransmit power: 13.5dBm; Carrier error: 0.005%Harmonic radiation: -32dBm; Modulation method: FSKNominal/maximum frequency deviation: +/- 65KHz; Maximum input level: 250mVInput impedance: 2.2K ohm; Input gain adjustment range: 4 adjustable settings, every 3dB step; Frequency setting: manual button settingcolour: blackMaterial: PCSize: 96x60x18.8mmPackage Contents:1 x Lavalier line1 x Mobile phone cable1 x Camera cable1 x Mobile phone holder1 x Hot shoe seat1 x EVA bag1 x receiver1 x transmitter1 x English manualOnly the above package content, other products are not included.Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing.
