Hieroglyphic Opalina Filter Network Module

A dual-channel stereo state-variable filter network offering two distinct operating modes for spectral shaping and crossover duties. Resonator mode configures three band-pass filters to emphasise formants and resonant peaks, while Isolator mode uses a cascaded topology with variable mid-bandwidth for resonant crossover applications.

The fully analogue signal path provides individual inputs and outputs for each band, continuously variable band input levels, and a soft-clipping circuit on the summed output. Designed for stereo use, it delivers flexible frequency sculpting in a compact 14hp Eurorack module.
