ABOUT THE T 75 4
Though the T 75 4 is among the most technically sophisticated A/V receivers, 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 a few examples:
• The T 75 4 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 topol-
ogy 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 multichannel
modes alike. NAD’s exclusive Soft Clipping™ circuitry further enhances sound quality and dynamic
potential.
• High-performance components used throughout the receiver’s analog audio circuits maximize quality from
all sources, including multichannel 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.
• Second Zone (MULTISOURCE) pre-amp feed with assignable 12 V DC trigger control.
• Gold-surfaced connectors are employed throughout to ensure maximum signal integrity.
A key element of the T 75 4’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 75
4’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. The T 75
4 also incorporates a second proprietary surround mode, Matrix 7.1. This creates a full
6.1/7.1-channel environment from stereo and surround-encoded recordings, oftentimes with extraordinarily
good results. Dolby ProLogic II Music and DTS Neo:6 Music modes can also create enjoyable experience
from 2-channel sources.
On the digital side, the T 75 4 combines extraordinarily high-speed DSP processing employing one of the most
advanced high-speed DSP “engines” available, with fully 24-bit, 96 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.
Despite the effort NAD has invested in the T 75 4 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
2 universal remote control is equally understandable, as are the T 7
54’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 keypress.
The T 75 4 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.
The T 75 4 receiver is equipped with a second Zone control of the Pre-amp level audio outputs from the
second Zone remote control ZR 2. Completes access to volume, On/Off, and all audio analog/digital inputs,
including the local input is available.
