Meet MP-532

The MP-532 is a multipurpose processor for FM, AM and HD Radio and includes RDS, multiplex power controller and WheatNet IP audio network interface in one rack unit. This multipurpose audio processor has all the critical audio shaping tools of a full service processor but without having to commit to a large expensive box with bells and whistles you may not need.

MP-532

FM/AM/HD/STREAM MULTI PROCESSOR
  •  Exceptional Audio Quality: Delivers clear, detailed audio with airy highs, well-defined mids, and deep, powerful lows, thanks to its advanced processing techniques.
  • Loudness and Clarity: Equipped with distortion-canceling algorithms and precision look-ahead limiters, resulting in impressive loudness while maintaining audio purity.
  • Advanced AGC Technology: An intelligent five-band AGC (iAGC) and five-band limiter offer superior real-time program density control, ensuring a consistent and balanced sound across a variety of source material.
  • Deep Bass: The Bass Management System is sidechained, resulting in increased depth, feel, and clarity of bass impact without affecting mid and high frequency program.
  • Exclusive Multipath Control: The Stereo Multipath Limiter mitigates multipath interference, improving the overall listening experience by reducing stereo blending issues.
  • Redundant Processing: As a multipurpose processor, the MP-532 is ideal as a backup at the ready for all broadcast services, whether AM or FM.  
  • Integrated Features: Includes a built-in RBDS/RDS encoder and a multiplex power controller, eliminating the expense and need for additional equipment.
  • FM Multipath Mitigation: Includes multipath mitigator algorithms to reduce the adverse effects of multipath such as receiver-induced stereo blending. 
  • 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.
  • WheatNet IP Compatibility: The MP-532 integrates with the WheatNet-IP audio network, enabling remote control, preset management, and more.
  • Flexible Connectivity: Supports analog, AES, and WheatNet IP inputs and features various output options, including analog composite, SCA inputs, and AES digital output.
  • User-Friendly Interface: A full graphic user interface allows for intuitive local and remote control, making adjustments and customization straightforward.

OVERVIEW

MP-532, FM/AM/HD/STREAM MULTI PROCESSOR

MP-532 gives you audio quality and “loudness-ability” courtesy of advanced distortion canceling algorithms and precision look-ahead limiters to provide pristinely clean audio and dial-dominating loudness. It includes FM RDS capability so that $500 RBDS/RDS encoder won’t be needed to generate song, title and album data. A multiplex power controller is included, meeting the ITU-R BS.412-7 modulation requirements for reducing adjacent channel interference and saving you yet another costly unit.

MP-532 REMOTE APP
MP532 - RDS Data

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).
