Shelves Expander

The 4 HP expander of the original Mutable Instruments Shelves: the HP, BP and LP outputs of its two parametric sections, wired to the back of the 16 HP module (the later 18 HP Shelves has them on its own panel).

Key features

• Six outputs: HP, BP and LP of parametric section 1 (raspberry arrow) and of parametric section 2 (turquoise arrow)
• The parametric sections are full state-variable filters: each output is one of their filter responses
• Connected to Shelves (original) by two ribbon cables at the back; no controls of its own
• Analog, DC-coupled signal path
• Made from 2015; the design is open source
