Feature:1. 2.4G wirele transmiion:2.4G wirele communication is used between the transmitter and the receiver, with long transmiion distance and low delay, and the sound data can be transmitted stably in complex environments. Using precision ceramic antenna, with scientific layout design, to achieve a wirele transmiion distance of up to 40 meters. Two-channel radio system. Composed of one receiver and two transmitters, it can capture two sound sources at the same time, perfectly solving double VLOG and double live broadcast.2. Digital display:Both the transmitter and the charging compartment are equipped with digital display, and the function and power display are clear at a glance. 360° high-fidelity pickup. Using high-sensitivity microphones, combined with digital proceing technology, restores high-fidelity sound quality, and can record clearly human voices, ambient sounds, and musical instrument sounds.3. Plug and play. One-click noise reduction. Long-lasting battery life:Insert the receiver into the device, take out the transmitter from the charging compartment, and you can put it into use. Toggle the side slide key, the noise reduction indicator lights up, that is, the noise reduction function is turned on, and the operation is simple. The battery life of the transmitter can be up to 9 hours. When used with the charging case, the battery life of both transmitters can be as long as 33 hours, improving work efficiency.4. Light and portable:10g for the transmitter, 5g for the receiver, and 55g for the charging compartment. The receiver and two transmitters can be stored in the charging case, which is very easy to carry5. Excellent compatibility:The receiving end supports Type-C and 8 Pin outputs, all kinds of cameras and computers, suitable for major mainstream software. Various usage scenarios. Such as video recording, interview recording, online teaching, outdoor sports and other usage scenarios and various live broadcast software.Specification:Certification: CEOrigin: Mainland ChinaStyle: Lavalier MicrophoneUse: Home StudioTransducer: Condenser MicrophoneSet Type: Transmitter SetsModel Number: Lavalier MicrophoneCommunication: WirelePackage: YesPolar Patterns: OmnidirectionalName: 1 to 2 wirele lavalier microphoneColour: BlackInterface: For Android Type-C, for Apple 8 Pin (optional)Transmiion protocol: 2.4GTransmiion distance: 20m1 to 2: Support (two transmitters and one receiver)Headphone monitoring: The receiver and the transmitter can be monitored at the same time (adapted to Type-C analog interface headphones)Noise reduction: SupportReverb: SupportSound delay: 25ms (18-22ms)Microphone: -42±2dB omnidirectionalFrequency Response: 20Hz-20KHzSampling rate: 44.1KHz (32KHz noise reduction)Signal-to-noise ratio: 70dBWorking current: 12mAShutdown current: 20uASingle microphone battery life: 9 hoursThe battery life of dual microphones at the same time: The longest battery life with the charging case is more than 33 hoursMicrophone battery: 110mAhCharging compartment battery: 600mAhCharging case battery life: It can charge two microphones 2.7 times at the same timeInput voltage of charging box: DC4.5-5.2V (support fast charging adapter)Adapter: 5V/1AWorking temperature: -10-50Size:Transmitter: 4.6x1.6x1cm/1.81x0.63x0.39inReceiver: 4.2x1.5x0.72cm/1.65x0.59x0.28inCharging compartment: 7.7x6.2x2.7cm/3.03x2.44x1.06inWeight:Transmitter: 10g x 2Receiver: 5gCharging compartment: 55gColor box size: 120x82x32mm/4.72x3.23x1.26inSingle weight (including color box acceories): 130gNote:Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
