When the M15 was introduced in 2005 it redefi ned the performance and value expectations for consumers worldwide. With a string of rave
reviews and awards including the prestigious EISA Award for ‘Best Home Cinema’, the M15 has become a classic in its own right. There is now
a new generation of video source and display products that support high resolution video and high defi nition audio. The new M15 HD has been
re-engineered to take full advantage of these new High Defi nition formats. We have also added some interesting new features to enhance your
enjoyment and protect your investment.
The surround preamp processor serves as the ‘brains’ of
your surround sound system. It takes the raw, unprocessed
digital audio signals, decodes them into multiple (5.1, 6.1,
or 7.1) analogue channels, and sends them on downstream
to your amplifi er and speakers. Compatibility is an important
issue, as there is a multitude of different audio and video
formats that must be catered to, with provision for several
different types of signal transmission. Whether it is digital
or analogue, the M15 HD has the fl exibility to accept all the
popular formats, including the latest, HDMI (High Defi nition
Digital Interface).
Once the signal arrives at the M15 HD’s input, it must be
buffered, identifi ed, decoded, and any ‘post processing’
routines (like Audyssey XT Pro) must be applied before
the signal is converted from digital to analogue and sent
to the outputs. There is also a requirement to ‘redirect’
bass frequencies, depending on the capabilities of the
particular speakers used in your system. All this processing
is controlled in the M15 HD by the latest high speed DSPs,
loaded with NAD’s proprietary software. These DSPs are
capable of 100s of millions of operations per second!
Fortunately, we use all this processing power to keep the
everyday operation of the M15 HD as simple and intuitive as
possible. Once the system and user preferences are set, the
M15 HD operates very much like our stereo preamplifi ers.
