NOTE: The PTH-2A is provided as a cost reduced option, available for Windows and Mac VST / Audio Unit only. Please see the PTC-2A / EQP-1A emulation for the fully featured Vintage Pultec EQ plug-in including VST3 and AAX compatible versions.

A cost reduced alternative to the full Pultec EQP-1A emulation with the essential signature vintage sounds.
Applying bass boost without loss of definition and focus can be a challenge, even for modern digital equalizers.
In contrast, the elegant simplicity of the vintage Pultec design, renowned for its signature 'low-end trick' - the ability to boost and cut low frequencies at the same time - adds powerful, tight bass boost without sacrificing detail.
Emulating the vintage Pultec EQH hardware, the plug-in provides a subset of the more feature rich EQP-1A. The characteristic separate boost and attenuate controls shape the frequency response, while the same innovative algorithms used for the PTC-2A / EQP-1A recreate a genuine analogue filter response without requiring conventional CPU intensive techniques.

Latest Version:
Mac Audio Unit 32 & 64Bit   V2.2.0
Mac VST2 32 & 64Bit   V2.2.0
Windows VST2 32 & 64Bit   V2.2.0
Separate LF Boost and Attenuate Controls   Simultaneous low frequency boost and cut, emulating the classic Pultec 'Low-end trick'.
Three LF filter frequencies   Switchable to 30Hz, 60Hz and 100Hz, provides a subset of the PTC-2A / EQP-1A ranges.
Five HF / Mid Boost frequencies   Provides a subset of the PTC-2A / EQP-1A ranges.
Physical Control Weighting   Replicates the 'feel' as well as the look of high quality rotary controls.
Passive Filters   6dB / Octave passive filter emulation maintains the smooth frequency response and desirable control interaction of the original vintage designs.
Transformer-coupled gain stage   Similar to the original Pultec EQs, the passive filters are followed by a transformer-coupled tube amplifier stage which further enhances the vintage qualities.
Analogue Filter Modelling   Analogue Filter Modelling algorithms recreate natural analogue filter curves, without requiring high sample rates or CPU intensive upsampling, allowing more plugin instances in a typical DAW.
