8 Channel AES/EBU Broadcast Audio XLR to Fiber Converter

The AES/EBU audio XLR to fiber converter adopts digital code technology, which of the audio interface is a balanced XLR interface, it can realize bidirectional long-distance transmission of the 8-channel digital audio signal by single-mode optical fiber, and the maximum transmission distance is 120km.

The AES/EBU audio XLR to fiber converter consists of a transmitter and receiver, which can be assigned 4 bidirectional or 8 unidirectional audio.

● Full-digital optical fiber transmission platform, flexible configuration of multiple services on the same platform;

● 19 inch 1Ualuminum alloy anodized shell, IP40 protection grade;

● Use FPGA, digital decode and clock recovery technology, high integration and high stability;

● The audio interface is XLR balanced interface and the audio power supply is a large-power Toroidal Transformer +-18V power supply, a high dynamic range;

● The three standard sampling frequency are 32kHz,1kHz,48kHz, can be supported simultaneously;

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

● Single fiber transmission, the dual fiber is optional;

● Various power supply ways are optional: AC220V, DC-48V/DC24V etc. It supports dual power: AC+AC, AC+DC, DC+DC.

● AES Audio Interface

input&output interface: XLR

input&output impedance: balanced 0dBm/110Ω 

Sampling frequency: 48KHz, 44.1KHZ, 32KHz
