How low can you go?

My 402 arrived yesterday but I won't open it before christmas! Meanwhile I'm still searching the web for hints, howtos etc... see my delicious links.

During the holidays I will lift the input pin  of the voltage regulator found inside the mixer (I mean the output of the diodes bridge) and feed the regulator with various voltages to see how low it can drop without impacting the Mackie analog circuits (don't know yet what will be the criteria). I guess Vin is 25.4 Vpeak (18 Vrms) minus two diode voltage drops. In order to minimise the risk of messing with the Mackie internal analog and injecting noise, I'll stay en amont of the regulators even if that means a lesser power efficiency (shorter battery life). What do you think?
