[QUOTE="mat3833, post: 8782382, member: 587645"] What did you use to generate the waveform? Voltage is hardly irrelevant. Voltage and current are the only things an amp really cares about. The amps circuitry doesn't have a way to measure the load its driving(ok, not technically true in modern digital amps but it's irrelevant here). Everything is about x voltage and y current. That's how basic protect circuits work, by measuring current and or voltage and shutting down if a limit is reached. That's how the clip light most likely works if it's not chip controlled. But even if you disregard the voltage numbers, the clip lights in my experience were turning on before the waveform was actually clipping at the terminals. No 2 amplifiers are the same, neither are any circuits really. There will always be small variations in resistances or capacitance or inductance, etc. Naturally that means everyone's clip light will, with a 99.9999999999999 percent chance, act differently. The quality of the components can majorly affect the consistency of the clip light as well. With all this taken into consideration, if I were a manufacturer selling to the broad market, I would engineer my "clip light" to turn on early. Better that than it turning on late. Matt [/QUOTE]
