Title: Kleinulator Rack Mount-switching mods Post by: hywelg on November 18, 2008, 08:16:31 PM I'm about to start building a Kleinulator kit from Nik into a rack chassis. I want to have a bypass switch hardwired, plus a footswitching (with LED) bypass so i also got an OTS relay board from Nik to do this ( I will use a 10v relay, can't seem to find any 9v ones in the UK)
Now the only problem is my logic thought processes are not as good as they could be so I have drawn a layout and I think it should work OK but I could do with some of you guys to look it over for me. Much appreciated Hywel Harris EDIT: removed attachments as the switching layout was incorrect and I modified it considerably. see my other thread.http://ceriatoneforum.com/index.php?topic=840.0 (http://ceriatoneforum.com/index.php?topic=840.0) Title: Re: Kleinulator Rack Mount-switching mods Post by: nickm57 on November 19, 2008, 04:55:16 AM To cut down on the signal path and chance of failure.
Why not use the dumble style of foot switching and only use the relay as the switch with a manual control. Wire it so if the relay fails it defaults to the way you either prefer bypass or loop. nick Title: Re: Kleinulator Rack Mount-switching mods Post by: hywelg on November 19, 2008, 10:39:24 AM To cut down on the signal path and chance of failure.

I wanted a quick and easy method of bypassing the whole rack if I needed to, just like in hardbypass fx pedals.

When there is no power to the relay, wire it so it is in bypass mode.... Then all cables you deal with only switch the relay.(no signals) Nick |
