INTRODUCTIONABOUT THE T 775Though 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 “MusicFirst” design philosophy. Here are just few examples:• The T 775 uses NAD’s proprietary Power Drive™ amplifier technologyfor all channels to preserve accurate, linear reproduction regardlessof the loudspeaker. This uniquely efficient power-supply topologyprovides the real-world benefits of high dynamic power that remainsuncompromised by low-impedance speakers. The result is dynamic,detailed, “un-receiver-like” sound in stereo and multi-channel modesalike. NAD’s exclusive Soft Clipping™ circuitry further enhances soundquality and dynamic potential.• High-performance components used throughout the A/V Receiver’sanalog 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 potentialexpansion 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 througha Windows® compatible PC.• Gold-surfaced connectors are employed throughout to ensuremaximum signal integrity.E.A.R.S. AND DIGITAL SURROUNDA key element of the T 775’s unique musical aptitude is NAD’s proprietaryEnhanced Ambience Recovery System (EARS). In sharp contrast to many“ambience-synthesis” music-surround modes, EARS exploits the T 775’ssubstantial DSP power to route the ambient content that is “encrypted” invirtually all natural-acoustic recordings to the appropriate main, center andsurround speakers, without resorting to artificially generated reflectionsor regeneration. EARS’ natural ambience yields a subtle but exceptionallyeffective surround mode that naturally enhances the spatial presentation ina fashion suitable for serious music listening.Dolby Pro Logic IIx Music and DTS Neo: 6 Music modes can also createenjoyable experience from 2-channel sources.On the digital side, the T 775 combines extraordinarily high-speed DSPprocessing employing one of the most advanced high-speed DSP “engines”available, with fully 24-bit, 192 kHz-sampling-capable D/A converters forall channels. A single, high-precision master clock synchronizes all digitalcircuits to eliminate the timing errors (“jitter”) that otherwise compromisesonics. The result is legitimately state-of-the-art surround decoding fromDolby Digital and DTS sources, and 6.1/7.1-channel reproduction, withgenuinely superior sound quality in all modes.EASE OF USEDespite the effort NAD has invested in the T 775 A/V Receiver’s sonicperformance, we expended no less in making it powerfully easy to use.Its design is uniquely simple for so sophisticated a component, and theHTR 3 universal remote control is equally understandable, as are the T 775’sown front-panel and on-screen displays. Its simple yet powerful systemof “presets” permits you to fine-tune your listening setup for differentconditions, sources, or listeners, and to recall these multiple parameterswith a single key press.INTEGRATIONThe T 775 A/V Receiver offers extensive, flexible system-integration optionsthrough its configurable DC trigger outputs and input, and its standard-protocol IR communications links. The DC trigger outputs can be assignedto either Local and/or Zone locations.ZONEThe T 775 A/V Receiver is equipped with three configurable Zones thatmake full use of video and pre-amp level audio outputs. The ZR 4 remotecontrol will allow you complete access to Zone 2 applications includingaccess to volume On/Off and all sources inputs. Zone 3 and Zone 4 couldbe configured and managed at the appropriate Zone OSD menu using thefront panel navigations keys as well as the corresponding keys on the HTR 3remote control.RS 232Flexible system configuration is possible with the RS-232 interface andNAD’s proprietary Windows® compatible software. We are also certifiedpartners with AMX and Crestron and fully support these external devices.This interface allows complete remote control of the T 775 from any remotelocation via the PC. Complete remote control functionality is available tothe user by interface software. See your NAD audio specialist for furtherinformation.UPGRADABILITYThe T 775/V Receiver permits flexible system growth via individuallyaccessible pre-out and main-in jacks for all channels. We have made themore likely scenario of software upgrades easy to accomplish via the highspeed RS-232 port on the rear panel of the T 775. Owners who registertheir T 775 on our international web site www.NADelectronics.com will beadvised of updates. Some of these may be free of charge, and some mayrequire royalty payments depending on the type of upgrade. The advanceduser will be able to perform these upgrades by downloading files from ourweb 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 beable to assist in performing these upgrades.ABOUT THE HTR 3 SYSTEM REMOTE CONTROLPacked with your T 775 is the NAD HTR 3 remote control, a full-systemremote especially designed for easy use and understanding. Be sure to readthe section “Using the HTR 3 Remote Control”, to familiarize yourself withthe remote’s layout and operations before proceeding to setup your A/VReceiver. You may opt to use your HTR 3 as your primary way to commandyour entire A-V system. The HTR 3 can be employed to operate additionalNAD or other-brand components such as a DVD/CD player, television,satellite/HDTV tuner, VCR, or virtually anything else that operates viastandard infrared remote5ENGLISHFRANÇAISESPAÑOLITALIANODEUTSCHNEDERLANDSSVENSKAРУССКИЙ
