Model FCA-A4Z
Description :

The device adopts digital coding technology, and the audio interface is XLR, which can realize bidirectional long-distance transmission of audio.

Overview

The device adopts digital coding technology, and the audio interface is XLR, which can realize bidirectional long-distance transmission of audio, data, dry contact, and ethernet signals through a single-mode optical fiber, and its maximum transmission distance is 100 km without distortion or relay. The audio interface uses a 24-bit AD/DA converter and a 128K sampling rate, and it has studio-level transmission quality. It comprises a transmitter and a receiver, and it can be configured into 2-channel bidirectional audio mode and 4-channel unidirectional audio mode.
