Hey all, noticed something a bit odd today when I was applying a high pass filter sweep over a snare drum. I have my snare drum sitting at -10 db, but as I begin to cut low frequencies I end up actually losing headroom, and it ends up sitting at about -3.61 db(well by it, I mean the drum rack that the snare and filter are sitting in). I am quite confused how I appear to be losing headroom, even though I am removing frequency content.

Attached two relevant photos. For reference, my snare is the second element in the drum rack, and the eq is on the drum rack as opposed to on the snare.

1st screenshot is of the filter disabled and the rack metering at -10.10 db(side question, anybody have any idea why this is metering lower than the snare, since nothing else should be in the signal chain).

2nd screenshot is of the filter enable and the rack metering at -3.61 db.
