Wheatstone MG-1 Microphone Processor with preamplifier

The MG-1 is a flexible digital microphone processor. It offers unlimited presets, security and networkability in an all-digital framework, with parameters that are easy to set up from the GUI - all parameters of the MG-1 can be controlled to give each voice talent his or her own personal sound at the press of a button.

The MG-1 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 MG-1 adds absolutely no undesired coloration to the signal and faithfully preserves the sound of any microphone and talent combination.

The features on the MG-1 include 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 MG-1’s can be controlled, making multiple microphone processor management easy.

  • Control of all audio parameters

  • Intuitive PC graphical user interface (GUI)

  • High quality, low noise microphone preamp

  • Mic or line level out, selectable from rear panel

  • 24-bit A/D, D/A converters

  • Preset storage/recall via GUI

  • Variable frequency de-esser

  • Voice phase scrambler

  • Adjustable compression

  • Downward expansion

  • EQ: two-band parametric plus variable high and low shelving

  • Tunable high and low pass filters

  • FFT voice energy display via GUI

  • Quick save/compare function

  • TCP/IP Ethernet remote control

  • Takes up only one rack space

Wheatstone-designed Dynamics Control

A high performance de-esser and a smooth sounding, very low distortion compressor/limiter dynamics control section round out the MG-1’s offerings to create powerful and authoritative presence on production or on-air microphones.

Wheatstone-designed Equalization

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.

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 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.
Unlimited preset storage on the host PC
