4 Channel XLR Audio over Fiber Converter

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.

● The device has an IP40-rated aluminum alloy anodized shell.

● The audio interface is XLR balanced interface with a high dynamic range.

● Desktop type and 4U rack card type are available.

● Single fiber transmission and dual fiber is optional.

● The audio uses a 24-bit AD/DA converter and a 128K sampling rate for broadcast-grade transmission.

● The audio interface provides a 3-level lightning protection function, which can pass the test of ITU-T K.21  (10/700 μS), common mode: 6KV, impedance (40 Ω).
