By Magneto Audio Labs

Get more from the gear you already own 

Magneto Audio Labs created the VariOhm to give users ability to alter the impedance relationship between their microphones and preamps. By inserting the VariOhm between the mic and the preamp/interface, you now control this important relationship. Impedance values can be matched for maximum output or altered for additional tone settings for all kinds of different sonic texturing.


  • Provides unparalleled control over the impedance relationship between your microphone and preamp/interface.

  • Offers a wider range of tonal settings to choose from, allowing you to achieve the perfect sound for any project.

  • Transforms your current gear into a new set of sonic tools, expanding your selection of sonic textures and colors.

  • Precision construction and affordability make it a must-have tool for any audio enthusiast or professional.

About Impedance

Long recognized in technical circles, the impedance relationship between a microphone and pre- amp/interface affects sound greatly. Different microphones and preamps/interfaces have a range of impedance values that contribute to sonic texture. It can affect warmth, sizzle, clarity, grit and many other aspects of sound. Many classic microphone and preamp combos work well together because of their impedances.
