Amps with clip indicators that fire at 3dB below actual clip?

[QUOTE="John Roberts, post: 47633, member: 126"] Re: Amps with clip indicators that fire at 3dB below actual clip? Except the Vrail in most power amps are not regulated so it can be a moving target in the process... True clip limiters generally don't attempt to look at the voltage, and instead detect when the amplifier is on the edge of losing negative feedback control of the output. I guess a several dB before clipping LED could grab a reference from the unregulated supply that will track as the rails sag, but again, nobody I know wants to see 3 db before clipping. JR [/QUOTE]
