Microphone pickup input solution
This solution is specially designed for wireless audio transmission of traditional musical instruments and consists of a transmitter adapter and a receiver adapter. The transmitter adapter is connected to the microphone, and the receiving adapter is connected to the input port of the amplifier. The transmission and reception adopt a one-to-one pairing mode, so as to ensure that 4 pairs of wireless devices can be used in one environment, 48K sampling rate and excellent audio codec are selected, with rich harmonic components, sweet and loud sound, and low distortion.
