Doepfer

Hey guys,

So I've been putting together one of these Doepfer DIY kits, and have finally gotten to the point where I can test it. I basically followed the example drawing in the back of the manual. I have a couple of questions, if anyone can offer any help I'd greatly appreciate it!

1. When I first hooked up the audio out I got a lot of really horrible buzz, after poking around for quite a while I noticed that if I shorted the other side of the stereo 7mm jack to ground it seemed to get rid of the noise, but I had to turn my amp way up in order to hear it! Is this how I should have done this, or am I missing something altogether?

2. In general, how, if at all, should the metal face plate I'm using be grounded? At the moment it is not, I don't seem to be getting any additional buzz from touching the case.

3. When should the ADSR LED light up? For the longest time I hadn't seen it light up at all, but after some prolonged screwing around it would start to pulse, but I wasn't really sure what had happened to make that start working.

Again, any info at all would be appreciated,

Thanks!

This is very difficult to answer IMO as only you know what you all cabled.
I have bought this: http://www.schneidersladen.de/en/xaoc-devices-karl-marx-stadt.html and the module works perfect.

Have fun,

Haha, that is very true! I ended up making a panel using front panel express, and am pretty happy with it. When I get it all finished I'll upload some pictures. Part of my issue is a lack of understanding on what some stuff is supposed to do, I have plenty of electronics experience, but this is one of my first tries at audio stuff. So I hooked up a lot of things not really knowing what the end result should be, and just followed the recommendations from the manual. 

I am having a lot of fun with it, so far it makes some beep boop noises, which is what I was hoping for!

Thanks for your reply!
