Introduction
The 568.2 Digital Surround Processor
This allows the 568.2 to upsample the audio stream if possible
and process the signals at a higher rate, giving improved audio
performance.
Intelligent stream content information
With a conventional digital connection between a DVD-Audio
player and a digital surround processor, the surround processor
cannot identify whether the source material is music or a movie
soundtrack, requiring the user to manually select an appropriate
DSP preset depending on the type of source material.
The MHR Smart Link carries intelligent stream content
information from the DVD-Audio player, and this includes
information about the source material, such as the encoding on
the disc. The 568.2 can use this information to select a suitable
DSP preset, such as Trifield for two-channel music or PLII Movie
for a two-channel movie soundtrack. The MHR Smart Link even
allows the 568.2 to select the appropriate preset if you change
audio streams within a disc, or play a disc containing several
different types of audio material.
Enhanced source
To use this feature of the MHR Smart Link you simply identify
one multi-channel source as the enhanced source. For this
The 568.2 Digital Surround Processor incorporates the result of
many years of research and development by Meridian into
several innovative technologies, including Meridian’s MHR
Smart Link.
MHR Smart Link
The 568.2 Digital Surround Processor can be supplied with an
optional multi-channel input card, which provides a proprietary
multi-channel input called the MHR Smart Link. This is the
recommended way of connecting together a Meridian 568.2
Digital Surround Processor and a Meridian 598 DVD-Audio
Player when used together in a system, allowing the two units to
operate together in a fully integrated way.
The MHR Smart Link transfers six encrypted digital audio
channels directly from the 598 to the 568.2, together with
intelligent stream content information from the source, providing
several significant features and benefits over other methods of
connection.
Upsampling
The 598 can be configured to decode encoded audio streams
internally, and send out digital audio on the MHR Smart Link.
