INTRODUCTION
ABOUT THE T 175
Though the T 175 is among the most technically sophisticated A/V
Tuner Preamplifier, we worked hard to make it one of the most musically
transparent home-theater components available as well; this is what we
mean by NAD’s “Music First” design philosophy. Here are just few examples:
•
High-performance components used throughout the A/V Tuner
Preamplifier’s analog audio circuits maximize quality from all sources,
including multi-channel analog sources such as DVD-Audio and SACD.
•
Audio pre-out jacks make potential expansion as flexible as possible..
•
Zone pre-amp and video feed with assignable 12 V DC trigger control.
•
An RS-232 port for advanced zone control and software update through
a Windows® compatible PC.
•
Gold-surfaced connectors are employed throughout to ensure
maximum signal integrity.
E .A .R .S . AND DIGITAL SURROUND
A key element of the T 175’s unique musical aptitude is NAD’s proprietary
Enhanced Ambience Recovery System (EARS). In sharp contrast to many
“ambience-synthesis” music-surround modes, EARS exploits the T 175’s
substantial DSP power to route the ambient content that is “encrypted” in
virtually all natural-acoustic recordings to the appropriate main, center and
surround speakers, without resorting to artificially generated reflections
or regeneration. EARS’ natural ambience yields a subtle but exceptionally
effective surround mode that naturally enhances the spatial presentation in
a fashion suitable for serious music listening.
Dolby Pro Logic IIx Music and DTS Neo: 6 Music modes can also create
enjoyable experience from 2-channel sources.
On the digital side, the T 175 combines extraordinarily high-speed DSP
processing employing one of the most advanced high-speed DSP “engines”
available, with fully 24-bit, 192 kHz-sampling-capable D/A converters for
all channels. A single, high-precision master clock synchronizes all digital
circuits to eliminate the timing errors (“jitter”) that otherwise compromise
sonics. The result is legitimately state-of-the-art surround decoding from
Dolby Digital and DTS sources, and 6.1/7.1-channel reproduction, with
genuinely superior sound quality in all modes.
EASE OF USE
Despite the effort NAD has invested in the T 175 A/V Tuner Preamplifier’s
sonic performance, we expended no less in making it powerfully easy to
use. Its design is uniquely simple for so sophisticated a component, and
the HTRC 1 universal remote control is equally understandable, as are the
T 175’s own front-panel and on-screen displays. Its simple yet powerful
system of “presets” permits you to fine-tune your listening setup for different
conditions, sources, or listeners, and to recall these multiple parameters
with a single key press.
INTEGRATION
The T 175 offers extensive, flexible system-integration options through its
configurable DC trigger outputs and input, and its standard-protocol IR
communications links. The DC trigger outputs can be assigned to either
Local and/or Zone locations.
ZONE
The T 175 is equipped with three configurable Zones that make full use of
video and pre-amp level audio outputs. The ZR 4 remote control will allow
you complete access to Zone 2 applications including access to volume
On/Off and all sources inputs. Zone 3 and Zone 4 could be configured
and managed at the appropriate Zone OSD menu using the front panel
navigations keys as well as the corresponding keys on the HTRC 1 remote
control.
RS 232
Flexible system configuration is possible with the RS-232 interface and
NAD’s proprietary Windows® compatible software. We are also certified
partners with AMX and Crestron and fully support these external devices.
This interface allows complete remote control of the T 175 from any remote
location via the PC. Complete remote control functionality is available to
the user by interface software. See your NAD audio specialist for further
information.
UPGRADABILITY
The T 175 permits flexible system growth via individually accessible pre-out
and main-in jacks for all channels. We have made the more likely scenario
of software upgrades easy to accomplish via the high speed RS-232 port
on the rear panel of the T 175. Owners who register their T 175 on our
international web site www.NADelectronics.com will be advised of updates.
Some of these may be free of charge, and some may require royalty
payments depending on the type of upgrade. The advanced user will be
able to perform these upgrades by downloading files from our web site, via
e-mail and installing them by connecting the T 175 to a PC. Alternatively
the dealer from whom you purchased your T 175 should be able to assist in
performing these upgrades.
ABOUT THE HTRC 1 SYSTEM REMOTE CONTROL
Packed with your T 175 is the NAD HTRC 1 remote control, a full-system
remote especially designed for easy use and understanding. Be sure to read
the section “Using the HTRC 1 Remote Control”, to familiarize yourself with
the remote’s layout and operations before proceeding to setup your T 175.
You may opt to use your HTRC 1 as your primary way to command your
entire A-V system. The HTRC 1 can be employed to operate additional NAD
or other-brand components such as a DVD/CD player, television, satellite/
HDTV tuner, VCR, or virtually anything else that operates via standard
infrared remote.
