Wheatstone MP-532 MultiMode Broadcast Audio processor with 4 modes FM/HD or AM/HD, HD & Streaming

Wheatstone's new MP-532 audio processor is an affordable single-space rack unit that can handle any and all your broadcast processing applications – FM, AM, FM HD, AM HD, HD-only, or Streaming. It's priced so you can use multiple boxes where and how you need them without having to commit to a large expensive box with bells and whistles you may not need. It's the best way to install exactly what you need without spending a penny more than your budget.ImageThe MP-532 offers tools that can provide the most clarity and articulation of any processor on the market. Breathtakingly airy and silky highs with detail that you get from the finest hifi audio gear, mids that never overstep their thresholds insuring mud-free warmth and presence, and deep powerful lows that are sculpted to be richly detailed and free from the muck that bogs them down in nearly every other processor.

All that comes without having to give up volume - indeed, just the opposite. MP-532 gives you "loudness-ability" courtesy new distortion canceling algorithms and precision look-ahead limiters to provide pristinely clean audio AND dial-dominating loudness.

There's full FM RDS capability so that $500 RBDS/RDS encoder you were going to have to buy to generate song, title and album data won't be needed. MP-532 has a built-in RBDS/RDS encoder.

A multiplex power controller is included, saving yet another costly unit to meet the ITU-R BS.412-7 modulation requirements for reducing adjacent channel interference.

Unique to Wheatstone processors, the MP-532 includes our intelligent five-band AGC technology — or iAGC — coupled to a five-band limiter and stereo generator. The combination provides automatic and superior real-time program density control for a consistent, spectrally-balanced sound regardless of density variations in incoming source material.

MP-532 is part of the WheatNet-IP audio network, with a full-blown interface, so you can set up and trigger presets remotely now and add on to your WheatNet-IP ecosystem later. It also includes 192kHz digital MPX connectivity to the transmitter for end-to-end native IP audio quality. It is equipped with two analog composite outputs, two SCA inputs, balanced analog Left/Right outputs and an AES digital output which may be switched to deliver either discrete Left/Right or baseband192 digital multiplex signal. Input audio may be delivered via analog, AES or WheatNet-IP.

For local and/or remote control, there's a full graphic user interface that allows you to tailor every function of the MP-532, so tweaking and making changes is both intuitive and accessible.

    • Stunning audio with little or no distortion 
    • Fits perfectly into any/every broadcast workflow 
    • Can do double redundant duty easily replacing a processor on another feed
    • Multipath mitigation that can increase your listening area
    • Is a part of the WheatNet-IP Intelligent Network

Intelligent iAGC

Our adaptive iAGC – or intelligent AGC – allows unobtrusive transitions between hyper-compressed recordings and those with more dynamic range. Our iAGC effectively manages the behavior of the multiband AGC as program content density changes, something a typical broadband AGC simply cannot do. By coupling the iAGC and mulitband AGC, we are able to produce a consistent, spectrally-balanced sound regardless of density variations in incoming source material.

Smart Stereo Enhancement

The MP-532’s Smart Stereo Enhancement provides a wide but extremely stable ‘on-air’ stereo image. “Wide”, “alive”, “exciting to listen to”, and “very natural sounding” are terms customers have used to describe how our stereo enhancement method sounds. Users have reported hearing artistically important nuances in music that were simply inaudible when the same material was processed by competing products. Four band parametric EQ lets you tune in your signature sound.Image

Bodacious Bass Management System 

The MP-532’s Bass Management System circumvents bass-related distortion plaguing other broadcast audio processors. The result is increased depth, feel, and clarity of bass impact without affecting mid and high frequency program – in fact bass detail and the clarity of higher frequency audio are actually enhanced by the new algorithm.

Exclusive Multipath Control

Exclusive to the Wheatstone line of audio processors is the Stereo Multipath Limiter. A single user control assigned to this algorithm sets it to mitigate market and terrain-specific multipath behavior, reducing the annoyances of multipath-triggered receiver-induced stereo blending. For more info, click here 




Wheatstone baseband192

Wheatstone® baseband192 digitizes the entire multiplex spectrum including RDS and SCAs up to 80kHz, providing a higher performance interface than using the classic analog composite method between processing and transmitter. A single AES/EBU cable between the processor and a current solid-state FM transmitter carries the digital baseband signal, bypassing the need for multiplexing in the exciter and eliminating the resulting signal overshoot with its associated loudness tradeoff. 


MP 532 Remote App


Processing is as much art as science. If you’re more artist than scientist and have trouble keeping track of the dozens and sometimes hundreds of controls that modern processors offer, you are going to love working with the MP-532 Remote App which enables you to concentrate on what you hear, not what you see. It’s as if we send a processing expert with each box! The MP-532 Remote App, provided free with the MP-532, makes the tough, behind-the-scenes decisions based on the simple-to-use controls supplied for texture (Drive, Density, Loudness) and EQ (Low, Warmth, High).
