[QUOTE="helotaxi, post: 2601298, member: 550915"] You're taking the idea far beyond where I was thinking and getting the control too invasive. My basic though is simple level matching. You set the volume and the amp uses a table to match the max voltage at the max volume with the required input voltage to get max power out of the amp. I'm not talking a true smart amp (though I've seen a few on the market that start to attenuate when they detect clipping) just a simple gain level setting. The engineer should know what the amp is capable of and shoud be able to design a simple circuit that matches the input voltage with the needs of the output to keep from clipping the amp and at the same time get full (or at the very least rated) power out of the amp. Test CD costs less than $.25 to make so that's not really an issue. Would be much quicker than setting up the amp with a DMM or scope, calibration would take all of about 15 sec. If you wanted o be able to overdrive the amp, simply trick it by not turning the volume all the way up on the source during the setup, if you want to turn the level of that channel down, use an outboard unit. Most all worth having have individual level controls. Set the gain then turn down the level control. [/QUOTE]
