running a p3 from batteries?

2004-02-12 by Julian

Heys, 

Ive been toiling for the past couple of days on a new enclosure for my doepfer / analogue solutions modular.

The plan is to run the setup (12 x 86hp of modules) from a coupe of sealed lead acid batteries when on the move with it.

Now when the new run of p3s come through, im thinking a p3 would make a pretty complimentary addition to this setup.

Paul / Tony's poly dac will, it seems, run from a +/- 12v bus, so that part of it taken care of, but then on to the p3...

Now its late here, and i haven't looked at all of the schematics, but from my brief look, it appears that the 9v (or whatever) supply is regulated down to 5v.  Regulating a 12v supply from a SLA battery will, if im not mistaken, be a reasonably inefficient way of doing things.

Im wondering quite how bad the situation would be.  I was looking at a couple of 7.2ah batteries for the synth, and its probably about an amp of drain.  Providing the synth works out ok, what would be my best plan regarding the p3?


cheers, julian

(incidentally, the p3s din sync will be put to good use feeding into my battery powered, modded tr606 for a nice little self contained portable setup...)
