I have not measured it yet.

You know! If you sum two channels together as with the LFE channel the gain is +3db. What happens with +10db LFE? My guess is the 10db boost is thrown away.

You need a dolby digital test disc with the same frequency on both the LFE and main channels playing at the same time to check for clipping.

I made a test disc once to check LFE and bass management problems with the 568.2 on the old firmware that was configured wrong. Beta 2.5 fixed the problem. I could probably make a disc for you George! Actually I could just make a DD file and send it to you unless you have a DD encoder.

George! Have you tried creating an all digital speaker config that includes an LFE sub to see if all the channels are still -3db? I wonder if -3db is only for configs with no LFE or sub. Then another thought is what happens if your rears and center are set to small? Does Meridian throw away even more bits for headroom in the main channels?
