Sorry to post twice in one day! Does anyone know if there is a reason my A-111-1 doesn’t have a ‘normalised’ CV1 input? My A-110-1 breaks connection to the CV bus as soon as a cable is inserted which is how I understood it to work in general. However, the A-111-1 doesn’t which means I’m getting more control signals than I want! Thanks, Neill

But as far as I know it's described correctly in the user manuals of the modules. The A-110 uses a normalled socket with switching contact to interrupt the bus CV as soon as a plug is inserted into the CV socket at the front panel. For the A-111-1 (and all other later modules that have access to the bus CV, e.g. A-111-5, A-111-2) the CV's of the bus and the front panel socket are added. We found that this is more flexible than the normalling version. And there is another reason: over the years (the A-100 is nearly 20 years on the market) the switching contacts may wear out because of inevitable material fatigue or corrosion or unwanted dust between the metal parts of the socket. That why we try not to use normalled sockets if it's avoidable. Best wishes Dieter Doepfer

Thanks for the incredibly quick reply Dieter - I’m new to the Eurorack scene and have built a 100% Deeper system which sounds incredible. Just learning as I go! Regards, Neil

I prefer the normalized version of the connection myself because this allows to easily dis-connect the VCO from the bus when wanted. I often do this when using the Buss Access modules on a cabinet with more than one "receiver" from the bus. Often a situation will come up where you want to NOT have the VCO transposed by another signal on the bus. It also adds to some confusion when you have a VCO changing pitch (from the bus) when you are doing it from another module and forget about the normalization. I would probably not use the built in connection and make a separate one through the normalized jacks myself. I understand doing this on modules that only have one front panel CV in like the A-111-5 though, Doing this allows it to have 2 CV ins when normally it doesn't. Not much room to add a jack there. -James
