Modular Design Construction
NAD has developed a unique new (MDC) architecture that keeps pace with the fast
changing world of digital formats by allowing connectivity and feature upgrades
as new technology becomes available. This prevents premature obsolescence by
keeping pace with the latest developments in high performance audio and video
formats. Dealer installed hardware and software can add new connectivity and
features at a future date, allowing your T 175 to grow as your needs and tastes
develop. Most AV tuner preamplifiers require complete replacement with a new
model to get the latest features. With NAD you only replace the module you want
to upgrade - not the entire AV tuner preamplifier!
Separates vs. Receiver
Separate components have always been used in professional applications and
occupy the highest tier of performance for consumer electronics products. Simply
put, the receiver concept makes compromises in performance and flexibility in
favour of convenience and price. This is especially true for the power amplifier
section of the receiver. The large power supply and output stage heat sinks of the
power amp must be compromised to fit in the single chassis format of the receiver.
These high power parts can also cause interference with the low-voltage sensitive
circuits used in preamplifier, tuner, and decoder sections of the receiver. The T 175
combines all the control and decoding functions in one compact chassis, giving up
nothing for the convenience of the receiver, yet gives a big jump in performance
and flexibility by separating the power amp stages. The 5-channel NAD T 955
and the 7-channel T 975 power amplifiers are perfect accompaniments to
the T 175.
Audio Performance
Today’s advanced Surround Sound processsors require quality in the digital
decoding stages, the video processing section, and in the power amplifier design
for the best overall performance. The T 175 is an excellent example of the NAD
Design Team’s expertise in all three areas. Not only that, but we have made many
ergonomic refinements to simplify operation and make it more enjoyable to get all
the performance from this magnificently capable AV tuner preamplifier.
Using the latest Dual Core Floating Point DSP technology, NAD was able to include
the newest surround formats from Dolby and DTS, as well as NAD’s own highly
regarded music surround mode - EARS. The EARS circuit (Enhanced Ambient
Recovery System) is now optimized for 7-channel surround. Unlike the typical
artificially enhanced DSP modes like ‘Club’, ‘Stadium’, and ‘Church’, EARS uses
DSP technology to extract the natural ambience of the recording. This is redirected
to the surround channels to create natural surround sound from any 2-channel
source. This induces a warm natural reverberant effect without the hollow ‘BOING’
of artificial reverb.
The surround mode of the source material is automatically detected via the digital
inputs of the T 175 and the most advanced form of decoding is switched in.
Conversion of the encoded digital bitstream is performed with high resolution
and extremely linear D/A Converters carefully selected for their performance
capabilities.
Credit for the sound of NAD’s components rests squarely with our unique design
approach and our experienced and very talented design team. Most companies
design their products to a technical specification and a price point. While this
sounds logical enough, it does not address the way the product will actually be
used by the eventual owner. You don’t listen to specifications – you listen to music
and sound. While NAD products exhibit excellent technical measurements, we
have relied on our own ears and listening experience to determine the final design
of our products. Because of our unique design approach, NAD’s sound is simply
more real sounding, adding enjoyment and excitement to your favourite films and
music recordings.
Video Performance
The T 175 features NAD’s newly developed HDMI repeater featuring Sigma’s
VXP Image Processor. Both analogue and digital video sources can be selectively
processed using Sigma’s advanced VXP algorithms. This is the best performing
image processing engine we could find, and the T 175 is the lowest priced AV
tuner preamplifier on the market featuring this advanced technology.
