Mike..
I thought I was reading a script from Monk.

Fact is, I have two PSR 2000s and the monster cable did not work with either of them. So...does the incompatibility lie with Monster or Yamaha? Hmmmm.

I sent the stereo cable back to Monster and they are making a mono for me. Which means I will most likely have the most expensive, one of a kind, mono, 6 1/2 ft., XLR>1/4", Monster cable in the world.
