Limiter circuit response must be clean sounding with no apparent pops, noises, or pumping.2. Plate dimensions not to exceed 11.81"H x 7.87"W and the plate must be airtight with no possibility of air leaks (plastic cover required).3. 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.4. ALL SPECS SHOULD BE MEASURED AT NOMINAL LINE VOLTAGE.ES150P3
