We hand-build a range of real tube audio devices, using audio electronics technology originating around 1950. Because we like it that way
— Jakob Erland (Gyraf's mastermind)
The Genius Of Simplicity
[...]I found the G21 to work exceptionally well on virtually all of the sources where I could also see the benefit of printing the final mix to tape [...]
[...] the G21 can prove an astonishingly versatile and powerful machine when controlled by the right pair of hands [...]

About us

Gyraf Audio is an audio electronics manufacturing, research, and development company, situated in Aarhus, Denmark. Originally founded in partnership with one of Denmark's largest recording studios, the now defunkt  Feedback Recording.  

Product Development

For product development, we use our associated studios and engineers as guideline for new designs, developing our products in close contact with full-time recording staff. This Real world verification is by far our most valuable design evaluation tool - and it enables us to explore technologies where few have been before. 

Technology

We hand-build a range of real tube audio devices, using audio electronics technology originating around 1950. Because we like it that way. But as we're not purists, we use modern solid-state electronics for non-audio purposes - like power supplies, metering, and sidechains in the compressors. Likewise, the G21 "Magneto-Dynamic Infundibulum" contains a variety of semiconductor elements in the signal path, but used entirely in passive mode.

Manufacturing

In our manufacturing, we focus on hand building single units or small series of 2-4 units at one time - we have never tried our hands on mass-production, as this route makes no sense for our designs, which rely on massive amounts of careful selection of components. And yes, every single unit is still handbuilt by yours truly (!!).

Product range

Our product range covers a broad range of equipment intended for recording and mastering: Microphone preamplifiers, Equalizers, Compressors, and even the occational passive soft-clipper. See under /Products for the entire range

Tubes and the future

In our products, We use only NOS (New Old Stock) tubes of the highest quality, but still we base all our designs on readily available tubes, most of which are in current production - because it's important to know that availability of spare tubes is not going to be a problem anytime soon-
