The M4IP-USB is a four-channel DSP-based BLADE-3 voice processor with four completely independent channels of high-quality, low-noise, high-dynamic range and accurate transient response voice processing in an IP networked rack unit.
The M4IP-USB combines four high-quality microphone preamps, four channels of Vorsis embedded microphone processing, and a WheatNet-IP BLADE interface, allowing you to place four microphone inputs anywhere in your WheatNet-IP Intelligent Network (although it also works just fine as a standalone processor). The preamps and processors are accessed and controlled from any point on the network via its Windows-based GUI.
Four independent USB ports are built in to facilitate the individual use of each processor output by separate computers.
The M4IP-USB is a great way to maximize your investment in on-air talent by combining four mic processors into a single rack space, accessible from anywhere.
The M4IP-USB microphone processor is equipped with four 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 96kHz base sample rate, the M4IP-USB 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, and de-esser and expander functions.
The M4IP-USB also features four analog stereo line-level outputs, ideal for feeding headphone amplifiers associated with talent or studio monitoring systems, and four stereo AES digital outputs.
The signal path of the M4IP-USB includes four completely independent channels of Wheatstone’s smooth-sounding Vorsis dynamics processing. Adjustable from anywhere on your network the M4-IP offers the security of password protected TCP/IP-based remote control and no front panel controls.
Like all WheatNet-IP BLADE-3s, the M4IP-USB is AES67 compatible.
WHEATSTONE-DESIGNED EQUALIZATION
Based on great-sounding designs built for Wheatstone’s high performance professional audio applications, the M4IP-USB’s equalization section operates predictably and adds no noise, ringing, phasiness or other undesirable coloration to the sound.
WHEATSTONE-DESIGNED DYNAMICS PROCESSING TOOLS
A high performance and fully adjustable downward expander, de-esser, and smooth sounding broadband compressor and selectable low distortion final Lookahead limiter round out the M4IP-USB to create powerful and authoritative presence to production or on-air microphones.
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.
WHEATSTONE TALENT CONTROL INTERFACE
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 Vorsis microphone processor without allowing processing adjustments.
All parameters of the M4IP-USB are controlled using the included Windows-based GUI. 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.
