    Orban AM 9300 broadcast audio processor

     

    Orban AM 9300 broadcast audio processor

    Orban AM audio processor 9300 series is impeccable a product , powerful, easy to use.

    Orban 9300 AM all-digital audio processor can not guarantee the high quality audio signals in mono short wave, medium-wave and long-wave broadcasting . Optimod-AM can pass out loud , clear and free of impurities audio , as with FM audio simultaneously open , relaxed, deep enough to attract and lock the user . Because the math for audio processing rely on Motorola DSP56367 digital signal processing chip easy to get these things beyond the reach of analog processors .

    Meanwhile Orban also has about significant features:

    5 - Band limit with distortion - Cancel clipping limiter

    Finally clipping peak modulation provided over the last protection.

    Input filter regulator

    High-pass filter

    Low pass filter

    Technical Specifications ( for analog output to the left and right stereo mix output and FM analog left and right outputs)
