[QUOTE="thch, post: 2579103, member: 562032"] sure, this is a way to detect clipping. output increases by power-law as volume or gain knobs are adjusted. eg, e^x, as clipping starts, the percentage that each increase in HU volume (or gain) changes the RMS or average magnitude suddenly does not increase by power-law. (RMS and avg magnitude are different). you can plot HU volume settings vs output in a special way that will give an indication of what settings cause clipping. JL builds regulated amplifiers with high damping factors. Such amplifiers should have output voltage that are only marginally affected by the speakers. this method doesn't try to get the absolute max out of unregulated amps, as the orion method does. the load shouldn't affect the amp's output voltage. the amp should be rated for 4x power @ 1ohm vs 4ohm, and the output voltage for both cases should be the same. many people ask about impedance rise, when its not really part of the formula. if impedance is higher, the amp isn't capable of the same power output, and the recalculation gives the same results. the orion method works well with unregulated amplifiers, which are popular in SPL competition as they allow more power if you run higher power voltages. in such amplifiers, the point of clipping will be based on how much the load causes the supply to sag. the ideal setting will be affected by load and charging system, which do not appear on the amp manufacturer's specs.
