The PSP Impressor is an incredibly accurate, a fully-featured, high-precision compressor designed to process whole mixes, busses or single tracks. PSP Impressor emulates the magical classic characteristics of compressors with valve and opto-electronic circuits as well as classic modern compressors. PSP Impressor also features a highly configurable side-chain. The side-chain filter has a significant effect on PSP Impressor’s sound and operation. Depending on your side-chain filter settings, the filter also lets you use the compressor as a de-esser or to reduce the pumping effects of heavy kick drums and the like.
PSP Impressor also works very well in combination with the PSP Saturator. With the PSP Impressor before the PSP Saturator in the signal path (think of it like placing a bus compressor before a tape machine), you can employ both plug-ins simultaneously (using subtle settings!) in order to impart a very cohesive sound, like your mix was being produced on expensive analog hardware. Of course, you can also reverse the order, placing PSP Saturator before PSP Impressor – never be afraid to experiment!
Features
- A wide range of soft knee characteristics
- Peak or RMS level detection
- External or internal side chain signal with a smooth bell-type filter
- An output algorithm which can operate as either a brick wall limiter or soft saturation algorithm to preserve peaks above 0dBFS.
- New high resolution, scalable GUI.
- VST3 support.
- FAT quad sampling option.
- Entire compression engine runs at internal quad sampling for proper compressor modelling when FAT is disengaged and 16 x sampling when the FAT is engaged.
- High sample rate support up to 400kHz.
- Feedback and feedback + feedforward compression modes, PSP MixPressor runs only in feedforward mode.
- New side chain filter modes: HPF and Equal Power. PSP MixPressor only had its powerful Bell type side chain filter, however HPF gives PSP Impressor a more classic touch, and the Equal Power results in extremely transparent and well balanced compression of complex tracks, drum groups or even entire mixes.
- Four Auto Attack and four Auto Release modes instead of just two modes for each.
- Refined compression Shapes for added versatility.
- Adjustable Auto Makeup mode.
- Adjustable channel Link.
- Input (Pre) and output (Post) meter modes with optional Compare mode.
- Adjustable VU reference level.
- Adjusted ranges for most of knobs to make them more user-friendly.
- Input – Output knobs’ link.
- New output Limiter.
- Other algorithm refinements to make the PSP Impressor the natural tool of a choice for vocals, drums, acoustic guitars and other tracks, groups, and even during the mastering process.
