[QUOTE="Julian, post: 7777765, member: 625353"] there are two different types of regulation in amp power supplies and one type in the amp itself-----in the power supply there is input regulation and output regulation-----and there is degree of regulaton----input regulation means that the supply is designed to operate over a certain range of supply voltage---for example 10 volts to 16 volts----this means that the amp should perform well no matter what the supply is----now the degree of regulation determines just how good the amp stays within spec throughout that range----some amps are very tightly regulated and some are not at all and loose power at the lower voltages---as far as input regulation i would opt for good regulation-------power supply output regulation refers to the ability of the amp to maintain its rail voltages at a fixed voltage as the amp is called on to change from no load to full load----this factor determines more than any other thing the dynamic ability of the amp----if the supply is tightly regulated the amp will have the same continuous power as peak transient power----[B]if it is loosly regulated the amp will have the ability to produce undistorted musical peaks much higher than its continuous rating----- for this spec i would always choose the least regulation if the continuous power was the same between two amps[/B]-----the problem is most people don't know the difference between the two and seldom is it specified------there is a third kind of regulation-----this is output signal regulation and it indicates the ability of the amp to maintain a constant output regardless of load------this spec determines damping factor------as long as this spec is 30 or higher it is more than adequate....... by the way---there are no totally unregulated amps in either of the three catagories if the amps have switching supplies (meaning over 50 watts per channel)--some amps are just more tightly regulated in some areas than others--- an unregulated amp would never work in a car at all [/QUOTE]
