I've got a Sony str db930 and I'm no sure how to get the best sound out of it when listening to the music channels on sky. I used to set the sound field to '2 channel stereo' which was fine, but now I have bought a sub woofer and a new pair of fronts, things have gone a bit pair shaped. I've only recently bought a sub, mj acoustic pro 50, and I'm not sure how setting the sub to 'Yes' on the amp effects the bass levels sent to the front speakers. Putting the sound field on Auto Format Decode appears to make the amp realise it's playing 2 channel music and outputs to the front two speakers and the sub. Trouble is, the bass when listening to MTV from the sub is far too 'boomey' and drowns out the music. The subs settings are fine for normal TV and DVD, so I don't want to have to fiddle around the back of the sub every time I switch over to a music channel. If I change the sound field to '2 channel stereo' the sub is cut completely - but there doesn't appear to be any bass sent to the front two, which gives a really weak sound. I don't know what relevance the 'LFE Mix' setting has if the sub setting is on 'Yes'. Does the LFE mix only come into effect when the sub is set to 'No' and therefore the bass redirection circuitry outputs the lfe channel to the front speakers ? Front speakers are B&W 602. I haven't put the foam bungs in as I think this will reduce the bass even more. Any help would be appreciated.
