Yes, i have recently bought the gameboy battery pack.  it gives a pretty distinctive buzzing noise and whenever you use the battery or the charger through the battery pack.  it is also called the dmg-03 I think and i bought mine on ebay for about 15 bucks.  When you install prosound it should go away. (the buzzing)

any chance someone could post a link to a power supply that would get the job done?
jameco or mouser or something like that?
THANKS!

I can agree with that.

I'm a professional pro audio guy too - we use rechargeables for wireless theater mics. Never had a problem as long as we use a decent charging pattern (which is hard for theater). I've had even better luck at home with eneloop type batteries than with the more normal Energizer ones we have at work.

Besides, I'm just really not willing to use normal batteries in my GBs as I don't really consider it an option to generate that much garbage as a result of my art.

I've mostly dealt with battery powered mics when working on musicals; the transmitters for the actors lavalier mics. I indeed use standard non-rechargable batteries for that. But that's mostly to cut down work and expenses.
For consumer, home usage I see no problem using rechargables. But we all have different likings of course.

That's nice. I'll look into that. Restrict my batteries to a live situation only.

If you get the hum, the best solution for me was that rechargeable battery pack thats described in the 2nd post. The ac psu plugs into the battery pack and doesn't use the onboard plug. I got one from nonfinite.

I've done pro audio for years as a profession, this is just a preference. I've had a rough time with rechargables in mics and such.

Again, I haven't experienced any hum. Maybe the hum is a grounding issue of your household electricity..?

Why haven't I replied here yet?

Any voltage in the range 5-7 V DC will work fine. The trick is to find one with the right size that is also DC and center negative. If you find a plug of the right size, you can always repurpose it with a suitable transformer.

The hum is annoying but ultimately harmless. Unless you're recording and want a clean sound, of course.

Never ever experienced any flakeyness with my rechargable batteries. Most of my batteries are 2700mAh which gives me a good amount of lsdj time.

I get an odd hum when I use my wall wart for my DMG. So I don't. I just buy batteries in bulk from a local pro audio place. I pay like 13 cents on the battery. I'd rather have a fresh pair than deal with flakey rechargables myself.

I didn't get any hum with using a $15 radio shack'ish one. I've heard about people getting it though.

yeah I get crazy massif central hum and buzz.

its bee so long but doesnt the psu make it sound like shit?
