USB wireless receiving solution




This solution is specially designed for wireless audio transmission of electroacoustic musical instruments, and consists of a transmitter adapter and a USB receiver. The transmitter adapter is connected to electro-acoustic musical instruments, and the USB receiver is connected to the USB interface of a computer, tablet or mobile phone, which is convenient for network recording and sharing. The transmission and reception adopt a one-to-one pairing mode, so as to ensure that four pairs of wireless devices can be used in one environment, 48K sampling rate and excellent audio codec are selected, the harmonic components are rich, the sound is pleasing and loud, and the distortion is small.
