Based on good results with an ACP 88, and after looking at other candidates from Aphex, dbx, and others... I have just gone ahead and purchased an ACP 22 compressor. What I was wondering is this; does anyone have any "hands on" experience and helpful hints and tips they might be able to pass along? Mine will be used to keep the levels out of an Avalon U5 under control to both the FOH board and my on-stage rig. Thanx for your input folks!
