That’s a great page – thanks. I’m now totally confident that I’m not over-loaded, as I’m nowhere near 1200mA on either 12V rail. Best wishes. Tim Burgess From: Doepfer_a100@yahoogroups.com [mailto:Doepfer_a100@yahoogroups.com] Sent: 13 February 2018 12:08 To: Doepfer_a100@yahoogr

Hi, That’s very reassuring – thanks. A pack of 10 fuses arrived today and my wife has already re-seated my ribbon cables (a couple had definitely worked loose with all the moving around I’ve been doing). I’ll get a fuse in later today and keep my fingers crossed that it’s as simp

PSU 2 is the older supply, it’s definitely 1200 ma -12v, 1200 +12v, if you add a 5v adapter that takes some from the positive, depending on load. The current draw you listed should be well within limits. Get a few of those glass slow blow fuses, I was in a similar position a few

Hi, This is the point I’d like clarification on myself. A U.K. dealer has told me that there’s 1200mA available spread across both the positive and negative supplies, so I’m confused. Best wishes. Tim Burgess From: Doepfer_a100@yahoogroups.com [mailto:Doepfer_a100@yahoogroups.com

Hi, Thanks again for the information. I’m going to have to go with the cheap option for now by pulling out some modules and replacing the fuse. I’ll then start saving up for a PSU3 and an engineer, or maybe buy a new LC9 with a built-in PSU3 and keep my current LC9 for less deman

Hi Del, the specs are per rail, you don't add the currents for different voltages. It's fine to load +12V and -12V to 200mA each, simultaneously. In order to get the total power consumption you must first convert from current to power, ie 200mA @ 12V = 2.4W, 200mA @ -12V = 2.4W,

Hello, each of the four VCAs is equipped with a 47k input resistor (R1, R12, R23, R34). If you increase the values of these resistors (or add a trimming potentiometer to each resistor) the input signal is attenuated. You find the position of the resistors in the attached picture.
2018-01-09 by John Hollis
I find it is necessary to greatly attenuate a VCO output (say the sine wave from a A-111-1) to prevent distortion. I have adjusted the trimmers to get a full range sweep for an ADSR. Is there an input resistor that could be changed to remove the need for 2 x A-183-1 dual attenuat

Hi Dieter, Thank you very much for your assistance. The CV issue was indeed due the TUn value. The value was set at 255. I reduced to 55 and now I can hear the changes in CV signal, rather that what seemed like a constant high pitch tone prior to the change. I honestly don't know

Hello Colum, please check the parameters Scale (SCA) and Tune (TUn). Typical values for the coarse parameters are about 100 for SCA and 55 for TUn. If the values differ clearly (e.g. 002 instead of 100) they have to be re-adjusted. Concerning the USB freezing issue please contact

We handed over a few prototypes of the A-180-9 to customers who use the A-100 very intensively (live on stage and in the studio) before we started the production to find out if there may occur any crosstalk or voltage loss problems. Even worst-case scenarios were tested (e.g. 15V

I would modify it to have all the normalization on the separate jacks tied to ground so that any unused jacks would act as a ground connection and provide some shielding in the cable. If the jacks being used have a normalization connection that is floating now, it would be pretty
