Hi, I want to record Yamaha P-80 through Lexicon Lambda connected to a laptop with Cubase LE. 1. I take stereo output from P-80 and connect to Line 1 and Line 2 of Lambda. Even on a low gain it gives terrible noise. Even when Volume level is turned off on P-80. 2. When I connect the same cable to the amp Microphone INs there is no noise. ?! 3. When I take L/L+R out and connect it to Guitar input (Lexicon front IN). There is no noise. So I can record Mono. I would like to know why Line In gives a noise. Output impedance of Yamaha P-80 is 600 Omm. Thanks, Michael.
