Re: AW: AW: [Doepfer_a100] Re: A155 as a switch?

2007-02-01 by Bakis Sirros

hello Dieter,
ok, thank you for the info!
during my patching i do all kinds of crazy things with

negative voltage beyond 5 volts could be generated.
ok, i just hope that the a155 can stand it...   :-)
best regards,
Bakis.
