The M1 is a flexible digital microphone processor. It offers unlimited presets, security and networkability in an all-digital framework, with easy-to-set up parameters.

The M1 microphone processor is equipped with a Super-Quiet (SQ) microphone preamplifier featuring an extremely low noise floor, very wide dynamic range, faithfully accurate transient response, and ruler flat frequency response. Operating in harmony with high quality 24-bit A/D converters and a 96kHz base sample rate, the M1 adds absolutely no undesired coloration to the signal and faithfully preserves the sound of any microphone and talent combination. Either from the front panel, or from the GUI - all parameters of the M1 can be controlled to give each voice talent his or her own personal sound at the press of a button.

The features on the M1 include a four-band parametric EQ, high- and low-pass filters, de-esser and expander and of course, our proprietary Vorsis dynamics processing. The unit comes loaded with factory designed presets, and designing your own is easy, thanks to features such as "Quick Save" and 'Quick Compare" that allow you to toggle back and forth between different presets as you adjust them.

From one GUI an entire group of M1's can be controlled, making multiple microphone processor management easy.

Wheatstone-designed EQ

A very high quality parametric and shelving equalization is available to sweeten the sound of any microphone as desired without adding noise or undesirable artifacts to the signal.


Wheatstone-designed Dynamics Control

A high performance de-esser and a smooth sounding, very low distortion compressor/limiter dynamics control section round out the M1’s offerings to create powerful and authoritative presence to production or on-air microphones.

Wheatstone Processing Videos

In January 2017, Mike Erickson sat down with Scott Fybush to talk all things processing. We shot video of the conversations and got some exceptional stuff. Learn about what it takes to provide modern, airwave-dominating clean sound that listeners rave about.
