BRAND: Rare Waves

MODEL: Grendel Formant Filter v2.0

FUNCTION: Eurorack Synthesizer Module

PRODUCT DESCRIPTION: This listing is for a Rare Waves Grendel Formant Filter v2.0 Eurorack Synthesizer Module. The Rare Waves Grendel Formant Filter v2.0 (and its subsequent v2.2 update) is a 100% analog Eurorack filter module designed to synthesize human-like vowel tones from external audio. It utilizes a bank of four parallel bandpass filters controlled by a specialized CV processor that maps vowels to a two-dimensional X-Y space.

SPECS:

• Format: Eurorack module with a width of 12 HP.
• Depth: 30 mm.
• Power Consumption: Requires 65 mA on the +12V rail and 65 mA on the -12V rail.
• Voltage Range: Optimized for 0 to +5V or +/- 2.5V for Articulator inputs, but can accept up to +/- 10V.
• Filter Type: Four analog bandpass filters (BPFs) of original Grendel design configured in parallel. 
• Articulator X & Y: These two controls work together to navigate a "Vowel Trapezium" based on the International Phonetic Alphabet (IPA) Vowel Chart.
• Size Control: This parameter moves all four filters in parallel, effectively altering the simulated "size of the mouth" to produce deeper or higher vocal characteristics.
• Standardized Levels: Unlike v1, signal levels for both input and output are standardized for easier integration with other modular gear.
• Peak LED: Includes a central indicator that lights up when the filter enters overdrive, which users note for its pleasing distortion character.

ACCESSORIES INCLUDED:  

• Eurorack Power Cable
• (4) Eurorack Screws & Washers
