NAD T775 - Manual (Page 5)

INTRODUCTION
ABOUT THE T 775
Though the T 775 is among the most technically sophisticated A/V Receiver,
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:
• The T 775 uses NAD’s proprietary Power Drive™ amplifier technology
for all channels to preserve accurate, linear reproduction regardless
of the loudspeaker. This uniquely efficient power-supply topology
provides the real-world benefits of high dynamic power that remains
uncompromised by low-impedance speakers. The result is dynamic,
detailed, “un-receiver-like” sound in stereo and multi-channel modes
alike. NAD’s exclusive Soft Clipping™ circuitry further enhances sound
quality and dynamic potential.
• High-performance components used throughout the A/V Receiver’s
analog audio circuits maximize quality from all sources, including multi-
channel analog sources such as DVD-Audio and SACD.
• Preamp output (all channels) and main-amp input jacks make potential
expansion as flexible as possible.
• A second set of speaker terminals (Speakers B) for remote listening.
• 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 775’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 775’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 775 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 775 A/V Receiver’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
HTR 3 universal remote control is equally understandable, as are the T 775’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 775 A/V Receiver 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 775 A/V Receiver 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 HTR 3
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 775 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 775/V Receiver 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 775. Owners who register
their T 775 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 775 to a PC.
Alternatively the dealer from whom you purchased your T 775 should be
able to assist in performing these upgrades.
ABOUT THE HTR 3 SYSTEM REMOTE CONTROL
Packed with your T 775 is the NAD HTR 3 remote control, a full-system
remote especially designed for easy use and understanding. Be sure to read
the section “Using the HTR 3 Remote Control”, to familiarize yourself with
the remote’s layout and operations before proceeding to setup your A/V
Receiver. You may opt to use your HTR 3 as your primary way to command
your entire A-V system. The HTR 3 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
