The Kultube is a stereo compressor with three specialties:
Compression is done by a custom-made discrete Class A gain cell instead of industrial VCAs, the unique Progressive Time Control (PTC) automatically optimizes Attack & Release and an adjustable tube saturation.

- Class-A Gain Cells
- Tube Saturation
- Progressive Time Control (PTC)
They ensure the highest level of musicality and clarity in signal processing and demonstrate significantly improved distortion values over VCAs.
PTC can be seen as an interactively controllable automation which is not based on fix presets but reacts to the audio material in a musically useful way.
Applications cover those of a classic compressor for vocals and instruments, in both mono and stereo, through stereo operation for subgroup processing to stereo mastering and multi-channel/surround projects.
