I don't 100% understand this parameter. Something to the effect of the input voltage (from the pre/pro) to get full power from the amp. ?? OK, and then say I have 2 amps, 1 a 2 channel, and 1 a 5 channel, and will I have any problems if there input sensitivities are different? (2 ch is 1.1V, 5 ch is 1.5V) I'm guessing any problems would be say for level matching at different volumes. (I have this setup now, but haven't tested it yet.) Thanks!
