Gyratec G21 - Magneto-Dynamic Infundibulum

The G21 is kinda an elaboration on our G14 parallel-passive eq – the parallel topology enables multi-band control without running into the traditional problems in multi-banding.

G21 is as standard available as all mains voltages – it’s entirely passive, and does not have a power connector.


With a classic design the G21 will fit into every studio. The two handles make it easy to transport or move the product, and the material of the switches is a must feel experience.


As we all know, clipping generates harmonics – there’s simply no way around that. But what you do with those harmonics will make a lot of difference.

Why Passive?

In essence, we want complete control and predictability in the clipping process – and we want to preserve signal integrity as far as possible.


“ sounds rich and wide when appropriate, but absolutely pristine and clear when necessary. – Hannes Bieger, Sound on Sound

This is a great, unique, exciting box to work with.’s just incredibly useful, and there’s no way it’s leaving my studio.” – Bob Macc
