Re: [Doepfer_a100] Re: Voltage droop when using a quantizer

2009-07-10 by Sean Williams

Have you checked how much current all your modules are consuming? 
Maybe it's too close to the quoted maximum for the power supply. In 
my experience with the old style 650mA G6 cases anything near 600mA 
and things start to go a bit wobbly.
