Gyraf Audio G21 Magneto-Dynamic Infundibulum

The Gyraf Audio G21 Magneto-Dynamic Infundibulum is a true passive stereo soft clipper, based on paralleling multiple bands of frequency selective clipping with an overall clipper on top. It is primarily intended for time-constant-less dynamic control in mastering - but it has some interesting applications in recording, mix, and sound generation as well.

The Gyraf Audio G21 Magneto-Dynamic Infundibulum is kinda an elaboration on Gyraf Audio's G14 parallel-passive eq – the parallel topology enables multi-band control without running into the traditional problems in multi-banding. The  G21 is as standard available as all mains voltages – it’s entirely passive, and does not have a power connector.

Design
With a classic design the Gyraf Audio 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.

Tech
As you 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. Use carefully - this is in no way a fire-and-forget gadget: Multiple types of interacting nonlinearities are at large, even a few in macroscopic time-domain because of components heating and temperature coefficients. Changing something in one band will sure as hell result in something else showing up somewhere else. Feels organic in that. As you 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. The beauty is here, that as the clipping is done at the remote end of a frequency selective channel, the clipping byproducts (harmonics, at frequencies multiple times the clipped) have a hard time getting back out and into the audio, because they are now no more in the right frequency range.. And other than the three bands of clipping, you have an overall clipper that can be set for linear (white), pink -3dB/oct or red -5dB/oct emphasis - enabling gradually lower "threshold" at higher frequencies. Then there's a fine-trim for output level and a 18dB/oct lowcut at the input - mainly because most of Gyraf Audio's test pilots were mastering engineering.

Why Passive?
In essence, Gyraf Audio wants complete control and predictability in the clipping process – and Gyraf Audio wants to preserve signal integrity as far as possible. In passive domain, you are more or less restricted to what could be described as 'first order' non-linearities - you do not convolute clipping on top of clipping (i.e. distortion on the distortion products) like it would most often happen in an active circuit under feedback control. It's hard enough to navigate the nonlinear processes already - you do not want to add unnecessarily to the mess.
