Hi list,

My a-147 VCLFO seems totally frozen since Saturday morning: suddenly no more signal went out whereas two of the three leds remained permanently turned on (but did't flicker any more...)
If I switch power off and then on, two different leds came on, but I still don't have any voltage out, and therefore no lfo. Did it die? Any idea? Thanks!

i think this happens when one of the two power supply voltages (+12 and -12 volts) does not reach the module.

do all the other modules, that are connected in the same PSU, work fine?

of course, Dieter is the man to answer this correctly...

thanks,
Bakis.

If the module is connected in the right way to the bus board please send the
module for repair to the representative in your country where you purchased
the device.

Best wishes

Thanks Bakis and Dieter!

I tried to connect it to my 9U case and one of my 6U frames, unfortunately without success for the a-147… Other modules are OK. The lfo was bought at Thomann two or three years ago, I have to see with them how to return it for repair. Thanks again!
