Server 2012R2 Local Group Policy - Equalizer?

I'm running Server2012 on an audio computer setup.

While perusing the Local Group Policies (there are 1,866 of them) I stumbled across something that was like an audio equalizer. It was set to boost 6db at 80 Hz..
Now I can't find it again. Anyone know what policy?

This is probably not the right forum to ask. Very few people here are running WS2012. I do, but have no idea what you are talking about. I would try at the JPlay/Computer Audio forum (a lot of PC savvy people there and many using server 2012), or I wouldn't ask at audioasylum/pc audio forum as the knowledgeable folks there seem to have a herd view of the world and probably will come out answering from a preconceived notion.
