Other Parameters/Notes:
1. Limiter circuit response must be clean sounding with no apparent pops, noises, or pumping.
2. Volume control should be at the input buffer stage  in order to lessen the possibility of clipping the input section with highly dynamic audio material.
3. ALL SPECS SHOULD BE MEASURED AT NOMINAL LINE VOLTAGE.
