Hi everyone!
I need to repair a Ddrum AT module : the trigger inputs are not working and i have distortion on outputs...
Someone has the service manual?
The factory reset of drumkits doesn't worked...
Many thanks!

Kenjwright, thanks for your reply... but the first link you posted is a collection of USER manuals and sounds for Ddrum modules, and the second link is the USER manual of Ddrum AT that I already have...
Unfortunately I need the schematics or SERVICE manual of Ddrum AT or maybe the Ddrum 2 (that is similar to AT)...
Could you help me?
Thanks in advance!

Sorry, that was all I could dig up. I have never come across any service manuals with schematics included so that may not be available.

On my dd3, there are BC547 transistors on the outputs for muting when switching the unit on and off. I had a similar issue when I got the module second hand. Probably the AT has the same thing? Just locate the output op-amps and you should be able to find these muting guys there.
