Hello Friends,

My A124 (after only 5 months) doesn't work anymore! Just turned on my 
synth and no filtering is coming out (the day before was working...).

If a signal audio is coming in I can hear an attenuated signal when 
the mixer is on the "HP" side. The input level seems to works (can 
attenuate the signal in). The Frequency and Resonance knobs have 
absolutely no effect on signal. 

The version is "v2": the are no sign of burns or detached component. 
The received voltage is correct.

Any idea? Any similar experience?
What can be done ?

Thank you
Antonio

Hi Antonio,

It's not unknown for ICs to become loose in their sockets - check 
that they are properly seated by gently but firmly pushing down on 
them. Other than that, you'll probably have to contact Doepfer/your 
local dealer.
