Topic: Power Testing

I know this has been covered somewhere but my searching didn't really amount to anything.

When testing an external power source for a pre/adc, is it adequate to just turn on the 48V phantom power?  Or do you need to actually have the mics plug in and picking up audio?

Thanks,

Joe

Mics must be plugged in, since they draw power from the source.  I also like to run it infront of an audio source to make all the light flash as if it was a normal situation

yep, i run in front of my tv, like ive been doing the last two weeks to get my new 7.2v NIMH batts at their optimum performance, seems to be working

How does this help your battery perform better?

it gets conditioned more reliable and expected run-times

hmmmmm,   does that realy make a difference in how it works, or just gives an average time to expect it to last?

more so the latter, gives me anal-obsessive-ass an idea how long i can push her. and whenever runtime gets close, i can hotswap the batts! andf go for another 6hrs w/ the vc3+jb3 powering solution!

that makes lots more sence.   good idea too.

I'll add that you want everything running - mics plugged in, phantom on, sound going into the mics, gain adjusted to drive proper levels, recording device plugged into preamp (because whatever the preamp is driving also presents some load).

If you run an ammeter on a preamp, you'll see the current draw fluctuating with the music when you're using lots of gain!
