TX-SR507 Sound Mix Problem

I have a TX-SR507 and only have L,R and C speakers set up.
Audio/Video input via HDMI from either a DVD player or home theatre PC.

Speech volume is very low, so need to turn volume up, but action sequences are then to loud and need to turn volume down again.

How can I fix this up?

Thanks

Hi BD,
Please try running the Audyssey Automatic Speaker Setup again located on page 37 of your manual. If you do not have a manual here is our blog post on how to download one: http://onkyousacustomersupportblog.wordpress.com/2011/09/13/owner%e2%80%99s-manuals/
Thank you!
