the drawmer df320 is a single-ended, high quality noise reduction processor which may be used to significantly reduce the subjective effect of unwanted noise that might be present in an audio signal. unlike tape noise reductions systems, the df320 does not rely on the encoding of the original signal and it is effective not only against tape noise, but also against noise generated by signal processors or electronic instruments. high quality components are used throughout to ensure the cleanest possible signal path from input to output. conventional gates or expanders can only remove noise during low level sections or pauses in the material being processed but the df320 is active at all times, regardless of the signal level...
