FW: [AH] voltage compatibility between Serge and 15voltsmodulars (Roland

Hello Paul, Peter and list,
I have already found a solution for that.
Doepfer will make a special a180 multiple module with two 15volts input
and six 12volts outputs. I just have to pass the +15volts signals thru
this simple attenuator to become about +12 volts and everything is ok.
But, between my banana metalbox modules( I have the divider/logic, burst
generator and psycho lfo modules) and the banana serge panel of mine,
would it be a problem to connect directly? Will the serge accept up to
15volts?
If not, I just have to pass the signals thru attenuators, but I was just
asking if I could bypass them...
Btw, the list of Doepfer a100 modules that will not accept +15volts
signals was given to me by dieter doepfer...so, it IS an issue to watch
out with a few Doepfer modules. (although this list is a bit
conservative, just for the user to be on the safe side.)
thank you very much,
Best regards,    :-)
Bakis.

I'm not suggesting that patch cords with zeners across them 
would be ideal.
But, between the units listed by the original poster, I can't see a 
problem. I'm sure any analog gear should be able to stand a 
short on any output - and a zener is friendlier than that.
I can't think of an alternative, other than hacking gear to 
limit outputs to the lowest level.

On the other hand, has anyone had a case of any of the 
gear mentioned being damaged by +-15 signals?
