Classe Processor and Amp

I set up classe processor ssp 300 and a 3 channel amp. When I play blue ray video via Oppo the volume seems very low. The processor levels from 0-98 in volume. I turn up to 50 and still don't hear the sound I then turn up to 70 level and start hearing the sound. And it will get louder if I turn volume up. 

Just wonder any classe owners experienced the same thing or did I do something wrong?

thanks.
