Hi, I have just bought an MC1 and am very happy with it. However I have a slight problem. When I am playing DTS DVD's the Lexicon makes this loud noise - sounds like a fan starting up. When pausing or stopping the DVD you can hear it 'slow down' and stop. I am using a Pioneer 626 DVD player. Has anyone got any ideas why this is happening and what needs to be done to resolve it. Thanks Marc.
