battery power options for mic pre-amp? at DVinfo.net

Hi

Does anyone know of a battery option that i could buy for my studio microphone pre-amps? I have several good ones that run off standard AC wall-warts that supply DC power to the pre-amp. I thought if i can use battery power on my pre-amps i can save some money for field use.

many thanks for any pointers.

Depends, of course, on what your preamp needs for power. FWIW, I made several battery packs for field use for Rolls mixer/preamps, which take 12 volts at very small amperage, from 8-cell AA battery holders, some wire and cable ties, and the appropriate output connector, all bought at my local Radio Shack (tandy, I believe, in GB). Worked fine for recording pool feeds and other ad-hoc stuff such as that....of course, have to treat these gently, they're not rugged military-spec gear, but works in a pinch. You could get fancy with the basic battery holder and enclose it in a case of some sort, I suppose.../ Battle Vaughan

I run mine from a belt pack.

Battle, thanks, looks easy enough! So I will check Tandy for the right bits and bobs thanks.

Bill, thanks, huge amount of choice and price, how did you decide which one to get? And which one did you get?

Sherif,

I knew I wanted a belt pack for the audio person. I added up the power needs of the equipment I wanted to use and this was the one I chose.
