Hello...
I've done some run time tests with different power options.....just recording the tv.....I have been using SP C4's ......ToddR cables into the HD-P2....No preamp..Phantom power ON....24/48....Headphone OFF...First I tried a 12V 4500mAh laptop battery from Battery Space with NO batteries in the HD-P2 and got roughly 12.5 hours and 12.5 gigs.....Then I tried my 12V power Runner (the big one) and got roughly 5 hours......Then I tried some 2300mAh AA batteries and got 4.5 hours.......Hope this helps...Peace,,
ps...Hey Doug , put me on the list for the mod,,,let me know...thanks.......Peace
