Gyraf Audio Gyratec XXI - Magneto-Dynamic Infundibulum
- A true passive stereo soft clipper
- Primarily intended for time-constant-less dynamic control in mastering
- Two handles make it easy to transport or move the product
- An overall clipper can be set for linear (white), pink -3dB/oct or red -5dB/oct emphasis - enabling gradually lower "threshold" at higher frequencies
- In passive domain, you can preserve signal integrity as far as possible
The Gyraf Audio Gyratec 21 Magneto-Dynamic Infundibulum is kinda an update on the G14 parallel-passive EQ – the parallel topology enables multi-band control without running into the traditional problems in multi-banding.
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.
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 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. 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, there is an overall clipper that can be set for linear (white), pink -3 dB/oct or red -5 dB/oct emphasis - enabling gradually lower "threshold" at higher frequencies. Then there's a fine-trim for output level and a 18 dB/oct lowcut at the input.
You want complete control and predictability in the clipping process - and want to preserve signal integrity as far as possible. In the passive domain, we are more or less restricted to what could be described as 'first order' non-linearities - we 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.
