[QUOTE="John Roberts, post: 97330, member: 126"] Re: Behringer Inuke 3000 The -107dB number for the QSC amps seems like they could easily be audibly quieter. While perhaps not obvious, in use we operate amplifiers with significant voltage gain to make the large output voltage swings to drive loudspeakers. For the amplifier's self-noise to not compromise the console or source noise floor, it must be lower by this amount of amplifier voltage gain. Not obvious unless you designed power amplifiers. :-( JR PS: A DSP located inside a power amp should not be significantly noisier than inside a crossover in the path before the power amp while execution and individual component performance matters.
