I've picked up noise from a wifi modem before, only in some equipment though. From: Doepfer_a100@yahoogroups.com on behalf of a11@live.nl [Doepfer_a100] Sent: Monday, 13 June 2016 5:33 PM To: Doepfer_a100@yahoogroups.com Subject: [Doepfer_a100] Re: Loud ground loop hum This is pr

This is probably not precisely the case, but I thought to report this in here. There was a time there was appearing a sort of signal sound, when I was playing my modular. After some time I discovered that it was my internet modem. When I covered it with my hands, the sound disapp

Each of the 3.5mm sockets has a GND terminal and as soon as a connection is made to external equipment a GND loop may occur. If the rails are connected to GND/Earth or not is not that important (though they are finally also connected to GND/Earth via the front panels as soon as m

The hum is probably caused by a ground loop. Due to safety reasons all metal parts of the A-100 cases are connected GND AND to earth shield of the mains connector. If another component in your system (e.g. mixer, power amplifier ...) is connected in the same way a ground loop is

Hi Scott > I’m still interested in knowing what the original cause of the hum is (and a solution) if anyone knows. Hum can be a very complex topic. To know the cause one would have to know all your equipment and all the cabling. That is not doable via the net. 25 years ago I did

Ok, the Hum Eliminator worked. It’s nice and quiet now. Not the best solution, but certainly the easiest. I still have a big problem with all my envelope generators but I’ll start another thread for that. I’m still interested in knowing what the original cause of the hum is (and

Hi Thanks for the info. I just bought an Ebtech Hum Eliminator which I hope will do the same thing for me. I’m just rearranging modules so I’ll reply with the results in a little while. Thanks! Scott From: Doepfer_a100@yahoogroups.com [mailto:Doepfer_a100@yahoogroups.com] Sent: S

Hi 1. No the rails are not connected to ground. This is the way Doepfer built the box and I was not advised to change it. 1b. I do not know if the power supplies are connected to ground. They are covered metal boxes. I would have to rip them open to find out. There are ground wir

Hello 1.) are the power supplies and the rack rails connected to ground? 2.) is your studios power distribution wired as star system? It must be based on a single wall outlet socket and then a central power "multiple" (I don't know the right english word for that, sorry). Or you

Hi Scott, I have had the same problem. I still don't know what caused it, but putting a Proel Active D.I, box between the Doepfer's output and my amplifier did the trick - the ground loop hum was gone. Hope this helps. Kind regards, Ton

The characteristics of a synth’s sound has a lot less to do with the VCOs than the filters or VCA or the circuits between them. A properly made sawtooth or square or triangle or sine will sound the same as any other properly made waveforms. They will have the same harmonic conten

Hi. This will probably sound stupid, but it’s bugging me so I need to ask. I have a few older synths (Arp Axxe, SH-1000, SH-2, etc) that I love using because the sound is “sharper” (more bite) than modern synths. I can’t say I am 100% sure of this but I think there is a sort of “

The reverb tank is available as a spare part from the Doepfer representative in your country. But I have to point out that it's only a guess that the reverb tank is faulty. It may be also a defective module. To find this out module + reverb tank have to be sent in for repair. For
