Hello Michael,

I have my KN7000 connected direct to the amplifier using the Main Out with the red plug in the 'Right' and the other in the 'Left' - if it's any help to you.

I assume you have checked all the usual things such as: is the volume down or muted, is the modulation wheel up in the 'max' position when it shouldn't be. Are the Part Settings at an audible level or maybe turned off. Have you tried taking out the leads and replacing them. Do you perhaps need a new Mains lead (with constant use they can sometimes become split and therefore not make proper contact).

Finally are you using an SD Card if so, try another one, the first could be faulty.

When I had a similar problem many moons ago, it turned out to be the amplifier connection. The wires in my amp are only held in by clips and one of these had pulled away slightly.

Just some ideas for you. I'll be interested to know what the answer is if, and when, you find out.
