Wheatstone MP-532, FM/AM/HD/STREAM Multi Processor

Wheatstone MP-532, FM/AM/HD/STREAM Multi Processor

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 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.

Features common to all signal paths:

• 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
• Bass Management System
• High-performance low distortion multiband limiters
• Full metering for all Input and Output levels and Dynamics processing

Features common to HD/stream processing signal path:

• Separate low /high shelf and two-band parametric equalizer for contouring HD/stream spectral balance
• HD/Stream final processing accepts audio from unprocessed input, output of AGC, or output from multiband limiters
• HD/Stream processing includes BS.1770 loudness measurement and target loudness controller.
• Oversampled precision look-ahead limiters for exceptional final peak control
• Specialized dynamic high frequency protection for low bitrate codecs which can also operate in wideband (>12kHz) and <12kHz modes
• Precision ITU-BS.1770 loudness metering and controller with adjustable target loudness goals
• Full ITU-BS.1770 metering including 400mS, 3 second, 10 second, 30 seconds
