DBX was a closed system - a signal must first be encoded with their 
brand of noise reduction, then decoded upon playback. The idea was to 
reduce tape noise, not broadband noise like 78 surface noise

Unless they made a consumer device or open ended model, but I am not 
familiar with such

You would be wsting money and not happy with the results, I feel
