Ideally would not like to compromise functionality too much. Most
of the modules I'm building are EFM which are +-12v. Your
solution seems to be one of the more elegant ones but I'm still
undecided how I want to go about this. Hrm..<br><br>

<br><br>sorry - sent to soon (wasn't done blabbing!).<br><br>Most *will* work with a lower supply, the question is how well and how much<br>spec hack you're willing to tolerate. Critical adjustments such as 1v/oct<br>tracking, overall frequency ranges, etc will be compromised.
<br><br>As far as slapping a 12 volt regulators on every module you wish to step<br>down - you can do this, but add this up ten times and you're burning a lot<br>of juice unnecessarily. If I were going to do this, I'd add a regulator
<br>board at the power distribution stage and a separate 12 volt buss. You may<br>need more than one of these 12 power adapters, but this is an improvement<br>over a regulator for each module!<br><br>-P<br><br></blockquote>
