One-to-Many High-Fidelity Solution

This solution consists of one transmitter module and one or more receiver modules, requiring pairing for operation. It offers various input and output options including audio interfaces, microphone interfaces, and balanced or unbalanced interfaces. It supports a 48K sampling rate and exceptional audio encoding and decoding, resulting in rich harmonic components, pleasant and robust sound, and minimal distortion.
