Overview
Vorsis M2 Dual Channel Digital Mic/Voice Processor
Two Independent Voice Processing ChannelsThe M-2 is a dual-channel DSP-based voice processor which operates as two independent channels.The M-2 microphone processor is equipped with twin, matched Super-Quiet (SQ) microphone preamplifiers featuring 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 48kHz base sample rate, the M-2 adds absolutely no undesired coloration to the signal and faithfully preserves the sound of any microphone and talent combination. It also features a four-section equalizer with high and low shelving EQ and two bands of fully parametric EQ, high and low pass filters, compressor, de-esser, expander and limiter functions.Included in the M-2 dual-channel voice processor is Wheatstone’s smooth-sounding Vorsis dynamics processing, configurable to up to three bands of processing. Adjustable from anywhere on your network, the M-2 offers the security of password protected TCP/IP-based remote control and no front panel controls.
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-2’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.
