    feature

    ◆ 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;
