X-ValveComp from Solid State Logic is a fully-featured mono or stereo channel compressor with a full set of classic channel compressor controls and an added 'valve' emulation stage. The valve emulation stage sits after the compressor in the signal path and adds a variable degree of primarily 2nd order harmonic saturation and distortion that thickens and colors the sound. The compressor can be switched between Peak or RMS modes and has a full set of controls including Threshold, Ratio, Knee, Attack, Release and Hold. There are Input and Output Meters with separate kick down compression amount indication and Input and Output Level controls, plus a Gain Make Up control and switched Auto Gain Make Up mode. A dedicated wet/dry mix control facilitates parallel compression. Side Chain input, high and low pass filters can be used to trigger compression. X-ValveComp can be automated via standard DAW Automation data and has A&B preset 'slots' with an A/B switch for easy comparison of two different combinations of settings.
