Default C Audio RA3001.....I could do with some help!!

Hi All,
I am doing a mate a favour, I have an electronics background but have no real expertise in audio eqpt.
I am looking at an RA3001, I've looked through this forum and have downloaded some circuit diagrams from Crest Audio, which dont quite match up with what I am seeing.
The problem is that the output is very low. I have a scope on the o/p which is giving me about 10V p/p for max i/p but this goes right down when I attach a speaker. Only the first led on the front panel lights up even at max level. I have traced the input signal through the first quad op-amp and back to the board from the 'Level' knobs on the front panel and all seems fine. But my circuit diagrams dont seem to match up with what I've got here!!
If there is anyone out there who could spare some of their valuable time to help me out with a few pointers/ideas?
I would be extremely grateful.
