Thanks for the quick reply!
I just purchased the A-112 unit (from Thomann) and I wonder if this is covered under the warranty.
Greetings,
Lars

This issue has been discussed already in April 2008 in this group (startin a

message dated April 27, 2008).



You probably own an A-112 manufactured before May 2008. In April 2008 it

came up in this group that the R2M/A-112 combo has problems with the gate

transmission because the A-112 gate input had a 10k load that reduces the

gate voltage coming from the R2M to about 2V. And that's not sufficient to

trigger the A-112. All A-112 manufactured from May 2008 are equipped with a

100k resistor instead of 10k as we immediately changed the value of the

corresponding resistor.



If you are a bit familiar with electronics you may replace the 10k pull down

resistor at the A-112 gate input to a higher value (e.g. 47k or 100k). It's

the resistor R15 that is located just behind the Midi In socket (between

Diode D5 and capacitor C21).
