RE: AW: [Doepfer_a100] AD/DA module - CV sampler/ recorder application.

2008-01-05 by Anthony Rolando

Dieter, I might be misunderstanding the question, but wouldn't the output also need to be direct coupled as well? 
I am wanting to use the A-112 to record CV, and I figured DC ins and outs would be neccesary for this... From our past conversation regarding the A-112 I gathered that the out put of the is Inverted and has an offset of around +2.5V. So additionally circuitry would be needed to use the A-112 as a CV recorder, right?

Thanx,

Tony
