Lexicon MX200 very weak input/no input lights
I bought a used Lexicon MX200 and I have problems with the input signal.
I connected it to the AUX SEND / RETURN of the mixer (Mackie 802VLZ3) and it initially showed the first light at the input indicator, and soon nothing.
I also tried plugging it directly from the keyboard (Yamaha Motif XS).
Not even at the strongest signal from Yamaha does it show a single Input signal light. The Motf XS has a fairly strong output signal.
The output sound is distorted and very weak.
I did a Factory Reset, everything stayed the same.
I believe it is a malfunction but what kind?
