The MG-1 features the same circuit as the M-1, but without the front panel knobs and switches. All control is handled via the M-1 GUI. This reduces costs and can save trips to the rack room. The back panels of the M-1 and MG-1 are virtually identical making it easy to swap out one for the other if desired.
Wheatstone-designed Dynamics Control
A high performance de-esser and a smooth sounding, very low distortion compressor/limiter dynamics control section round out the M-1’s offerings to create powerful and authoritative presence on production or on-air microphones.
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 Processing Presets
A variety of ready-to-use factory processing presets are provided, carefully tailored for different processing goals and formats. You can select a factory preset, confident that it will sound great just as it is. Or use a factory preset as a starting point and create a custom sound for each announcer, then save the new settings as a personalized user preset. In a facility with multiple microphone processors, presets saved in one unit can be easily copied to the others.

M-1 / MG-1 Control GUI
The Control Software loads on an external PC. You can connect the PC directly to the processor, or install the processor on your station’s Ethernet LAN and access it from anywhere in your network (or remotely over VPN).
With Control Software no adjustment is more than two mouse clicks away. And unlike other processors, every processing control is available and labeled for exactly what it does, giving you ultimate power to create your ideal sound.
The remote control screen is divided into an upper control area and a lower dynamic section that includes real-time display of gain reduction as well as a frequency-domain graph that shows the spectral characteristics of your audio. Every screen also includes accurate metering of input and output peak and average levels. Tabs across the top of the GUI software allow immediate access to each section of the processing - parametric EQ, de-esser, filters, compressor and downward expander.
All parameters of the M-1 and MG-1 are adjustable using the included Windows-based GUI which can control as many as 254 M-1 devices.on.
Talent Control Interface
Voice talent can activate his or her own personal sound at the press of a button using the Talent Control Interface, a special GUI designed for preset recall only. The Wheatstone Talent Control Interface software can reside on an air studio/control room PC and gives talent the ability to recall presets from any Wheatstone microphone processor without allowing processing adjustments.
Factory presets are pre-installed and write protected.
New factory presets can be downloaded from the Wheatstone-Processing.com web site and installed via the Windows-based GUI software.
