Description :

E1 audio codec is designed with digital processing chip and large-scale FPGA, digital codec conversion and clock recovery technology.

Overview

E1 audio codec is designed with digital processing chip and large-scale FPGA, digital codec conversion and clock recovery technology. This device is suitable for broadcast source transmission.The audio encoder converts the input stereo audio signal by A/D digital codec conversion or data format, and then re-frames to form a serial data stream, and output by the E1 port.

Features

● Machine is a single board design;

● Use FPGA, digital encoding and decoding and clock recovery technology, high integration, high stability.

● The audio interface is the XLR card balance interface, the audio power supply is high power toroidal transformer +-18V power supply, high dynamic range;

● Use of advanced digital processing, clock recovery, digital codec chip, its performance is better.

● Panel has LED lights indicate working status in real time E1, a digital audio and stereo signals.

● Use of SDH, PDH, microwave 2M channel, point to point transmission of audio sources.

● Dispenser with E1 interfaces can be implemented out of the overcharged broadcast transmission of audio sources.

● Apply to provincial, city, county, township area network, to achieve ultra-long haul transmission of audio sources.

● E1 interface complies with G.703 recommendation, all-digital clock recovery and smooth phase-locked technology;

● Audio interface three mine, to IEC61000-4-5 (8 / 20μS) differential mode: 6KV, impedance (2Ω); common-mode: 6KV, impedance (2Ω) Standard

● Multiple power mode options: AC220V, DC-48V / DC24V and the like.
