I went through the set up on the HK 7300 audio settings and not sure what’s going on.

I took my time, strapped the digital RS meter to a camera tripod, bumped the AVR’s volume up to 75 dbs, use the C weighted with the response on ‘slow’, just like the manual instructed (I actually read a manual). I set all the channels the same.

So then I played with the different surround options the receiver has (Dolby dig, Neo6, Logic 7, DTS, Pro logic, etc….) and on all except Dolby Digital, the channels default to 0 db. But if I go back to DD, they are as I had previously set them. If I go back to one of the others and re-calibrate the channels, the previous settings for DD are changed. What’s going on?

Shouldn’t the initial calibration carry over to all the other surround modes? It’s quite frustrating haven’t to trim channels when I want to use a different surround mode.
