Inexpensive "NADY" Preamp and Phantom adapters
« on: January 24, 2007, 05:13:29 PM »
I was browsing Soundprofessionals.com.   They have "Nady" brand phantom adapters (NADY-CBM-40T) for $29 each.

Also, I saw NADY DMP-2 portable preamp for $70 at Musician's Friend.  This is a stereo preamp with phantom power that runs off a single 9V battery!  I'd be curious to see what is inside, but it is certainly cheap enough to buy and play around with.  I expect battery life would be poor (25mA current draw), but it looks interesting.

You can get that pre-amp cheaper than that: http://www.keenzo.com/showproduct.asp?ID=940621&ref=FRG1

I'd be intrested to see whats in here... almost worth it for the chassis, connectors and knobs. maybe a few caps and a couple of opamps could make it usable... Maybe it sounds great right out of the box. (not likely) . You da right  man for the job.

I'd probably order one, but I am in Canada and shipping hassles make it difficult.

After looking at the manual, this looks pretty cool.

-metal chassis
-48v phantom power
-9v DC powerable
-XLR inputs and outputs
-Optional limiter
-separate gain controls
-peak lights

Gee... If you can get one for around $50, it would almost be worth it just for the case and hardware.
If you get one, let us know how it sounds.

If anyone feels like ordering (and maybe chipping in some cost) let me know.  I'm willing to evaluate it and possibly do some mods.

Posting a picture of this thing because it took literally 10 minutes to find one on the internet.  None of the retail stores had pics of it and Google image search turned up nothing.  Might as well make the time spent somewhat worth it  :P

This preamp will be very hard to mod because of the surface mount components that it uses. I am going to purchase one as well just to check it out. I want to see how they are getting a single 9 volt to do all this. I think this preamp is way to big for stealth use but I think its worth checking out to see if it can be improved.

It all depends on the circuit layout. And how much of it needs to be changed in order to make it work. I am going to remove the limiter from the circuit all together because I don't think its necessary for live recording.

I will post pictures when I get one in my hands.

Did anyone get one yet? I have a bad feeling that the chips are all going to be blacked out or in house numbers.
So I cant figure things out. I had no luck what so ever getting a schematic from Nady, they consider it to be "proprietary" information LOL how the hell are you supposed to fix it??? Then Again I don't give out schematics ether so how mad can I be? I just want to take a look at the power supply section and see what they are using to get all that voltage from a little bitty 9 volt battery... I think it must be some sort of pump charge IC maybe even a few of them cascaded I found this little guy doing some research for my new upcoming product looks pretty promising... MAX1044 ic seems to be promising..

If anyone wants to buy it I would love to take a look but I am scared to be the first one :)

This seems to be the same make by a different distributor:
http://www.musik-produktiv.de/shop2/shop04.asp/artnr/100009940/sid/!18121995/quelle/listen
I got one of them last year and taped one show [superlux > hitec preamp > jb3]. It didn't come out to bad IMO. The battery stood for the 4 hour show. I put it aside, because I managed to get an ua-5 meanwhile.
If anyone is interested, I could open it and post some pics of the 'inner secrets', if this is of any help.

I would like to know if it puts out a true 48v DC for phantom power. Pictures would be nice too.
