Title: How long does Samson Mixpad 4 run on three 9Vs for power and phantom??
Post by: rdflash on July 02, 2006, 02:32:21 PM

Last night, after having 3 freshly re-charged 9 volt batteries in it...it craps out right near an hour of recording!?

They were measured at 9.5 volts on my battery meter thingy when I tested them and I put them in the mixpad as I was setting up.

I cant figure this out, but the last time I used them...DBT was 45 min...RRFB an hour...by time Black Crowes come on...No power left...I had the power and phantom turned off when not using.

Do you think the rechargeable 9 volts are just crappy, got them couple months ago on ebay..."McNair 200mAh"

I dont know much about the specs on the batteries and how long they last, but it seems to me, that I need more powerful rechargeable 9 v's.

Any info to help me not have my recordings shot would be appreciated!!

thanks

jon

I think I remember getting about 1.5 hours with three new Kodak alkaline batteries.

i got like 2hrs out of mine one time...  you could try to get some of those 9v batt clips from radio shack, and rig up a cable for the wal-mart style 9v batts...

get three of these...

and splice them to the end the cable coming from the wal-mart batt, and connect them to the existing 9v clips.  should work assuming the polarity is correct.  YMMV.
