Overview and specifications
| MAP I is Audionets' universal home entertainer |
With the MAP I Audionet
presents a new decoder system for high-quality home entertainment. The MAP I
decodes all home cinema and surround sound formats, allows the reproduction of 2
up to 8 channels, offers unique adjustment and correction capabilities, uses
newest interface technologies and is, because of its architecture, via software
and hardware updates always up-to-date for future applications.
As all
other devices from Audionet the MAP I garantees unique sound performance and
stands in tradition to its big brother MAP V2, which is for many experts one of
the very rare decoder preamplifiers at all, that uncompromisingly combines
audiophile sound quality with state-of-the-art home cinema technology.
|
| MAP I is leading in technology and equipment |
|
The MAP I decodes all
digital home cinema and surround sound formats, including Dolby Pro Logix IIx,
DTS 96/24 and via Audionets' highbit interface even DVD audio. This makes it
possible to drive up to 7.1 channels.
The unique delay-, speaker- and
bass-management is freely adjustable in all parameters. So, every speaker
ensemble can be configured.
The MAP I has a high-performance digital
parametric equalizer that can correct disturbing influences caused by your
listening room. Audionets' "intelligent sampling technology" and
"double-precision-bassmanagement" guarantee best sound performance.
| MAP I has unique interconnection and update
capabilites |
|
With its numerous
interconnection and update capabilities the MAP I is prepared for all tasks.
Amongst others there are seven digital inputs for sound processing, and DVI in-
and outputs for video processing.
The optional progressive scan card converts
interlaced video formats (e.g. from VCRs or SAT receivers) to high-quality
full-frame pictures for beamers, plasma TVs etc. The DVI option additionally
offers the output of these progressive video data in digital format.
The
controller is flashable. Updates are easy and the MAP I is always up-to-date.
For future applications USB controller and connectors are already
integrated.
A turn-table? No problem! With the high-value phono module the
MAP I is also prepared for this source and offers delicate sound reproduction,
even in surround sound!
The MAP I has a comprehensible and intuitive handling concept. In connection with the four-line display and the on-screen-menu all necessary settings can be configured easily. The MAP I recognizes the incoming signals and automatically chooses the right decoder. A manual change between the different formats is obsolete.
With the integrated Audionet HighBit-Link, high-resolution two- or multichannel signals from DVD audio can be received and processed in digital format. All settings and configurations can be assumed for this.
The MAP I has a high-performance equalizer that can effectively correct disturbing influences of your listening room. In connection with Audionets' intuitive analysis and correction software CARMA even laities can achieve almost professional results.
