PSP ClassicQ is inspired by various classic British-style equalizers. It captures the sound and flavor of famously musical high and low filters (such as those in early Neve EQs), melded to a very precise mid-range filter. In addition, PSP ClassicQ offers a selectable simulation of class A circuitry and output transformer for a unique, vintage-style color. To its classic features, PSP ClassicQ adds extremely useful features such as an adjustable high pass filter, switchable Q for low- and high-shelf filters, and a sweepable midrange bell-type filter. The design of PSP ClassicQ lends it especially well to fixing and shaping individual tracks.Features:• selectable simulation of class A circuitry and output transformer for a unique, vintage-style color• an adjustable high pass filter, switchable Q for low- and high-shelf filters, and a sweepable midrange bell-type filter• made especially well to fixing and shaping individual tracks requirements: PC• VST• Windows x32 or x64 (XP Service Pack 2, Vista or 7)• VST 2.4 compatible application• RTAS• Windows x32 or x64 (XP Service Pack 2, Vista or 7)• ProTools LE 8.0.0 or ProTools TDM 8.0.0 (or later)• AAX• Windows x32 or x64 (XP Service Pack 2, Vista or 7)• Pro Tools 10 or Pro Tools HD 10Mac (intel)• AudioUnit• Mac OSX 10.5 or later• 32 or 64-bit host application capable of running AudioUnit plug-ins with Cocoa view• VST• Mac OSX 10.5 or later• 32 or 64-bit VST 2.4 compatible host application• RTAS• Mac OSX 10.5 or later• ProTools LE 8.0.0 or ProTools TDM 8.0.0 (or later)• AAX• Mac OSX 10.7 or later• Pro Tools 10 or Pro Tools HD 10
