VP-8 PLUS Digital Audio Processor

VORSIS_LOGOThe Wheatstone VP-8 Plus multimode audio processor gives the cost/performance envelope a nice upward push. VP-8 Plus, the broadcast industry’s first multi-mode broadcast audio processor, is equipped with six built-in and highly specialized independent processing functions. Selecting a new processing mode is as simple as selecting it from the front panel or from within the Windows®-based Graphical User Interface. Mode changes occur in less than 2 seconds, with no reboot or 'memory bank selection' being required in order to change the VP-8 Plus to a completely different processing mode.

The VP-8 Plus architecture includes processing for FM (with built-in reference grade stereo generator and inputs for SCA or RDS), AM/AM-Stereo, and four specially optimized processing modes. These four modes have been specially designed and tuned for the challenges of codec-based mediums such as FM-HD, AM-HD and low bitrate applications using the MP3/AAC codecs.

With improvements to its processing algorithms, all new factory presets, new front panel setup capability, and new and easy to use “GUI Lite” processor tuning software, VP-8 goes to the head of the class as VP-8 Plus.

Remote control is via 100BaseT wired Ethernet and Windows®-based GUI software.

Six Specialized Processing Modes

The VP-8 Plus incorporates six highly specialized, built-in processing modes that may be changed at any time by the user.

Special processing algorithms designed by Wheatstone condition the audio appropriately for the special needs of each of the six operating modes. Audio is first pre-processed by a phase-linear four band AGC followed by an eight band multi-band limiter equipped with special mode-specific final processing. The final processing algorithms are unique for each mode and have been carefully designed to meet the special requirements of the intended audio transport mediums.

Regardless of the operating mode, the VP-8 Plus offers the best listening experience of any audio processor in its price range. The VP-8 Plus's built-in library of algorithms specifically addresses the special needs of FM, AM, FM-HD, and AM-HD, as well as High and Low bitrate codec applications.

Vorsis Bass Management System

A Vorsis innovation, the Vorsis Bass Management System (VBMS) circumvents bass-related distortion often plaguing audio processors. By monitoring program energy in the audio spectrum and manipulating the behavior of the final peak limiter, bass-induced intermodulation distortion is prevented. The result is improved bass impact and detail without affecting the clarity of mid and high frequency program -- in fact bass detail and the clarity of higher frequency audio are actually enhanced by the VBMS algorithm.

Smart Stereo Enhancement

The VP-8 Plus incorporates a new technology that we call Smart Stereo Enhancement. Operating in the sum and difference domain and under the management of specialized automatic level andspectral management algorithms, the resulting stereo image is wide and acoustically stable with no ‘hole in the middle’ effect. Producing a sound that has great depth of detail and is exciting to listen to, artistically important nuances in music can be revealed for the very first time. In fact, Wheatstone customers have reported hearing details in program material that were completely inaudible when the same material was processed by other brands of audio processing.
