Hieroglyphic Opalina Filter Network Module Including Expander - Black

The Hieroglyphic Opalina is 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.

Features

• RESONATOR Triple bandpass filters with vc peak span and resonance. 12db/oct filter slopes.
• ISOLATOR Cascaded state-variable filters with vc bandwidth and resonance. 24db/oct filter slopes.
• Completely analog signal path.
• Individual band inputs and outputs.
• Continuously variable band input amplitude.
• Soft-clipping circuit on SUM output.
• Dual channel for use in stereo (L & R).

Includes OPX Input Expander.
