[QUOTE="Ampdog, post: 60550, member: 144"] I would imagine that the 460W is idle consumption, i.e. with no signal on any channel. I would further think that the 125W/channel is "music power" or short term output, short enough not to discharge power supply capacitors significantly. This is not necessarily a blank cheat because the mark-space ratio in music is quite low. For normal music (whatever that might mean!) that could be the highest you would turn up to before audible distortion (i.e. clipping of peaks) sets in. The American figures of "music power" and 'sine wave power" are fair practical descriptions in such a case. Theoretically and mostly practically maximum 'music power' would be 40% higher than maximum 'sine power'. [As an aside, this is also a guide to what rediculous 'PMPO' rated amplifiers might really deliver - take a look at the mains power consumption and estimate from there.] [/QUOTE]
