You're right. 2 pin can not be connected. But my scheme may exist. You can also try to ground the pin 2 through the outlet. You can connect the transformer to the ground screen. We need to see how these changes will react very theremin. The main thing that in the audio signal does not appear excessive interference.
(I use an interpreter, so the translation may be inaccurate.)
cool, i'll give it a try. i already gathered most parts, even found a retired transformer in the studio, so far spent 5 euros. as soon as have my thing tinkered together, i'll try again to post some pictures.
The 5-pin DIN is well established in the audio world as a MIDI connector. Perhaps Moog himself set this dangerous precedent, but using it to deliver power seems to be asking for trouble.
(There was a recent kerfuffle and recall/rework over the 3-pin DIN line-out connectors on the Roland RD800 where the "mickey mouse ears" power cable they switched to just happened to fit them like a glove. In a perfect storm of idiocy all of the back connectors were located together and angled down, so one could easily fumble around hooking things up on a dark stage and fry the unit. The solution was equally boneheaded: permanently attach the AC cord + big ugly stickers.)
Eric,
maybe the interesting fact for you, but all the audio electronics in Russia has been equipped with 3/5-pin DIN connectors exactly for audio signal transmission purpose. The MIDI application has been exotic.
There were two competing standards: 3-left audio, 1-right audio vs 3-left audio, 5-right audio. The mono connection (pin 3) has been compatible with both.
Yeah, most audio connectors don't make sense from a make / break standpoint. Whenever I crack open an old TV or radio and see an RCA plug physically soldered to the jack, I think that's probably the best use of them (as a permanent connection).
If I were the 3/5-pin DIN czar I'd put the ground on the center pin and do my best to array the others symmetrically. And I would make all symmetric cables crossover cables.
You can see why new protocols call for new connectors that are incompatible with anything that came before. Some of the reason for this is signal integrity, but much must be to avoid all of the legacy plug pollution.
thanks X8!
the situation, now, is that im playing theremin on the street, and im tired to ask for 220, also sometimes i can't find. i had a roland street. it works also with 9v
so im thinking now to buy a battery, kind of motorbike battery 9v or similar and install a resistance to get 14v 200ma
is that possible from 9v go to 14 and 200ma?
thanks a lot!
good luck! =)
