PTEq-X is a digital recreation of three renowned vintage passive program equalizers, designed to capture the authentic characteristics of their original hardware. Each component in the signal path has been meticulously modeled to deliver an accurate analog sound while maintaining efficient CPU performance and real-time responsiveness. This careful attention to detail ensures that PTEq-X provides a faithful equalization experience with enhanced usability.

This equalizer plugin offers three distinct modules, each featuring analog curve responses that remain precise even at the highest frequencies. The integration of advanced triode stage modeling allows users to select from four different tube types, enhancing tonal shaping possibilities. Additional selectable frequencies and refined filter precision improve upon the original designs, broadening the plugin’s application across mixing and mastering tasks.

PTEq-X supports both mono and stereo processing with fully automatable controls, making it suitable for a wide range of studio environments. Features like switchable equalizers, tube stage modeling, and linear phase oversampling optimize CPU usage and reduce aliasing artifacts. Its global input/output controls and proprietary preset management system facilitate smooth workflow integration within hosts supporting VST or AU plug-ins.
