T 175 AV Tuner Preamplifier
The new VXP video board features video conversion to resolutions as high as
1080p and supports all SD and HD formats up to 2048 x 2048 pixels. Motion
adaptive de-interlacing with edge interpolation eliminates the jagged edge effects
common in lesser image processors. Film mode detection with output cadence
generation endows the video picture with a film-like smoothness of motion. The
programmable scaling engine also allows for aspect ratio conversion to perfectly
match the video source with the video display. Advanced noise reduction and
detail enhancement improve legacy analogue video sources to near HD quality.
Flexibility
The T 175 has all the flexibility required to serve as the command centre for even
the most sophisticated Home Theatre and multi-room systems. A full suite of
video switching caters to all the popular video formats (HDMI, Component Video,
S-Video, and Composite Video). Digital inputs (including a handy front panel
input) and outputs are available in both coaxial and optical formats to make it
easy to attach all your digital sources for playback and recording. Digital Inputs
are converted to analogue for use in Zone 2 and you can choose to convert unused
audio/video outputs for Zone 3 and Zone 4 use with independent source selection
and volume control.
With the T 175, NAD has made it easy to add more speakers for listening to music
in additional rooms or zones. Multi-room systems can be created using the Zone
2, 3 and 4 outputs to add amplifiers and speakers with the benefit of independent
source selection and volume control. A separate second zone remote is included,
and signals can be transmitted via remote IR sensors (not included) to the IR input
sockets on the rear panel of the T 175.
There are also 12 volt triggers to automatically switch remote zone amplifiers
on and off, and even an RS-232 data port for connection to highly advanced
automated control systems. Thoughtful features like discrete On and Off codes,
direct access to inputs and FM station presets facilitates the integration of the
T 175 into elaborate remote control systems.
An analogue 7.1 input is also provided for attaching a DVD-Audio player or any
other yet to be developed surround decoder, ensuring that the T 175 does not
become obsolete anytime soon.
Luxurious Simplicity
All the capability and flexibility in the world is quite useless if the AV tuner
preamplifier becomes too complicated to be operated by every member of the
family. NAD has taken special measures to make operation of the T 175 as logical
and straightforward as possible.
Initial system setup is best accomplished using your television monitor and the
clear and simple On Screen Display (OSD), which can be configured to also
give status updates as settings are changed in everyday use. Once the T 175 is
informed of your specific system setup, all settings are stored in a non-volatile
memory, making this a one time task. The informative front panel display indicates
complete information about the source being listened to or watched, including
selected surround mode and volume setting. The front panel display can be easily
customized by renaming inputs and even determining what information you prefer
to be displayed and when to display it.
Audyssey Auto Calibration is available using the supplied calibrated microphone.
Simply place the microphone in the listening position and select Audyssey auto-
calibration and the system automatically detects the connected amplifier’s
speakers, chooses the ideal crossover point to the subwoofer, checks speaker
phasing, and adjusts the levels and delays. These adjustments are made to a level
of accuracy that it would be difficult to duplicate by ear alone.
Audyssey MultEQ XT is the latest in digital sophistication, allowing for improved
frequency response in a large, family-sized sweet spot. Using the calibration
microphone to ‘hear’ your room, a series of test tones measure the speakers’
response and the room’s distorting echoes independently, and then calculates an
ideal response that minimizes the effects of the room’s echoes. While this sounds
simple, the digital technology that is required for this level of performance would
have cost many thousands of dollars just a few short years ago. But the electronic
technology is only half the story, since an advanced knowledge of acoustics is also
required to get good results from such a system. Working closely with Audyssey,
NAD’s acoustic engineers developed the final response curves that reflect our own
performance values.
Audyssey Dynamic Volume and Dynamic EQ work together to address the problem
of large jumps in volume when switching between different TV channels or when
advertisements are inserted into the program. There is also an effect caused by our
ears’ different sensation of low and high frequencies at different listening levels:
as the volume is reduced our sensation of bass frequencies is reduced more than
the midrange frequencies.
The T 175 tuner section can store a mix of your 40 favourite AM, FM and XM (or
DAB) stations for immediate recall. These presets can be custom named. And if your
selected FM station supports the Radio Data System (RDS), it will automatically
stream information about the station and music being played. We also include
a ‘Digital Broadcast Ready’ socket on the rear panel for adding outboard DAB or
XM modules. All the control software for these formats is included – just plug in
the module and start enjoying the clear sound and expansive content selection
available with Digital Radio Broadcast.
Five independent ‘Audio Video Presets’ can store speaker level and tone control
settings for instant recall, making it easy to custom tailor your system for different
types of program material. Encoded surround modes like Dolby Digital and DTS
are automatically selected if the program is so encoded. The T 175 also remembers
your last used settings when switched in and out of Standby mode.
The included HTRC 1 remote handset is in itself an engineering tour de force. Able to
control up to eight different components, an illuminated LCD screen clearly shows what
device is selected and what command is being sent. It has illuminated buttons for easy
operation in a low light environment, and the length of time the buttons are illuminated
can be easily adjusted. Remote commands for products not already included in the
HTRC 1’s memory can be easily taught to the HTRC 1. And the HTRC 1’s Macro
function allows up to 64 individual commands to be triggered by pressing just two keys.
With this feature, all of the commands required for watching a DVD, for example, are
executed automatically by the HTRC 1’s Macro function. There is also a USB port that
allows the HTRC 1 to be connected to a PC and using our freely downloadable program
from the NAD website, you can program, customize, memorize and clone the HTRC 1.
