8 Channel XLR Audio to Fiber Converter

View : 353
Type : XLR Audio over Fiber
Description :

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

Overview

The product adopts digital coding technology, 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. The maximum transmission distance without distortion and without a repeater is 100 km. The audio interface adopts 24Bit AD/DA128K sampling, with studio-level transmission quality. It comprises a transmitter and a receiver, and it can be configured into 4-channel bidirectional audio mode and 8-channel unidirectional audio mode.

Features

● The audio interface is an XLR balanced interface, audio power supply for the high-power toroidal transformer, + – 18V power supply, and high dynamic range.

● It provides ordinary desktop, mini-desktop, and centralized card racks in various ways.

● Single fiber transmission and dual-fiber is optional.

● When the device has no fiber signal, it can detect whether the remote device is powered off or the fiber is cut.

The audio adopts 24Bit AD/DA128K sampling, which has studio-grade transmission quality.

● It provides bidirectional asynchronous data (forward and reverse).

Asynchronous data has a transmission rate of 110-115.200Kbps or higher.

● Asynchronous data for RS232/RS485/RS422/Manchester code.

● 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).
