Wheatstone's new MP-532 FM 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.

The 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.
• Input accepts analog, AES3 and WheatnetIP audio
• AES3 digital input accepts 32kHz to 96kHz sample rates
• AES3 digital output sample rate automatically synchronizes to AES3 digital input
• Processing may be in stereo or mono fed from left or right channel
• Front panel headphone jack for monitoring input source audio and processed output
• Variable high pass filter and voice phase rotator
• Dynamic L/R correlation meter for assuring proper stereo channel phase
• Front panel setup and configuration reduces the need for a PC during installation
• PC-based Graphical User Interface, for easy setup, navigation, and remote control
• Four GPI triggers for remote control triggered preset changes
• Ethernet-based remote control via rear panel 100BaseT Ethernet port
• Four-band equalizer: low/high shelf plus two band parametric
• User-adjustable multiband crossover frequencies
• Multiband windowing spectral manager assures spectral consistency across program types
• Independent multiband compressor and leveler may be operated separately or in combination
• Newly developed Bass Management System
• High-performance low distortion multiband limiters
• Full metering for all Input and Output levels and Dynamics processing
