  • Page 21: Effect

    The audio signal will not be compressed if it stays below the threshold level. The audio signal will be compressed by the compression ratio (see Ratio for more information) if it rises above the threshold. AD-300 offers a threshold range of 0 to +21 dBu. Setting it to OFF disables the compressor.

  • Page 22: Expander

    The audio signal will be gain reduced by a ratio (see Ratio for more information) if it falls below the threshold. AD-300 offers a threshold range of -66 to -48 dBu. Setting it to OFF disables the expander.

  • Page 23: Limiter

    For example, a ratio of 4:1 means that if the input signal falls below the threshold by 1 dB, the output signal from the expander will be 4 dB lower than the threshold. The available ratios on AD-300 are listed as follows:  ...

  • Page 24: Gate

    ∞:1 Threshold (-6 – +24 dBu) is the signal level at which the limiter will be activated. Setting it to OFF disables the limiter. Attack Time (50 – 500 msec) is the reaction time of the limiter. The limiter has a much faster attack time than a typical compressor.

  • Page 25: Filter

    Filter Other than the dynamic effects, AD-300 also offers audio filters to allow either high or low frequencies to pass through. A low-pass filter attenuates content above a cutoff frequency (threshold frequency), allowing lower frequencies to pass through the filter.

  • Page 26: Firmware Update

    4. Firmware Update Datavideo usually releases new firmware containing new features or reported bug fixes from time to time. Customers can either download the AD-300 firmware as they wish or contact their local dealer or reseller for assistance. This section outlines the firmware upgrade process which should take approximately few minutes to complete.
