I'm hoping someone can help me out here. I have a Denon receiver connected to a dvd/cd, vcr, and Scientific Atlanta 4200hd cable box. I have the tape out connected to a separate amp that powers a pair of outdoor Russound OB6.1 speakers. Audio from the CD, and tuner sounds great. However, the audio from the SA4200hd box is horrible. It's way to low. Using an SPL I register a 10dB drop in volume. I changed the audio out setting of the cable box to varible and max'd it out. Still no good. Has anyone had any experience with a line level amplifier of any sort? Or does anyone have a solution for me? Thanks.
