Most A/V receivers available on the market today focus predominantly on
the Video and Surround Sound aspects, leaving the audio circuitry almost
as an afterthought. NAD firmly believes that there are many people for
whom music will always come first. With NAD’s reputation for high value /
high performance it was obvious that the Model T750 would have to please
Audiophiles and Videophiles alike.
ANALOG Do lb y Pro Lo g ic d e co d in g
Many manufacturers of AV products boast about achieving Dolby Pro Logic
decoding in the digital domain for their products. While it is true that this
may bring some advantages, NAD found that at this price level Analog
decoding is much preferable. The reasons are very simple: First, to do
decoding in digital domain, an analog Dolby Pro Logic source has to go
through a stereo Analog-to-Digital converter to make the signal digital so
the signal can be decoded. After decoding, 4 independent channels need
to be converted back to analog which requires 2 stereo Digital-to-Analog
decoders. It is a well-known fact that the sound quality of CD players
depends a great deal on the single stereo Digital-to-Analog converter that
is required. With three times the amount of converters required for Pro
Logic decoding, the potential degradation in sound quality is tremendous.
By staying in the analog domain for Dolby Pro Logic decoding, the signal
stays clean and crisp, without the harsh, digital artifacts that can mar the
performance of so many other Surround Sound receivers.
De sig n
By doing away with many costly and superfluous features, NAD’s engineers
concentrated only on the truly important parts of an A/V receiver. The NAD
Model T750 uses discrete output stages only, including the surround
channels. The benefits of this approach have been proven over the years in
many acclaimed NAD amplifiers and receivers. The integrated output
modules favored by so many other designs will deliver a decent amount of
power under laboratory conditions, driving an 8 ohms resistor, but can
have great difficulties in driving real-world loudspeakers.
Im p e d a n ce Se n sin g Circu it ry (ISC)
Fle xib ilit y
The new Impedance Sensing Circuitry (ISC) topology designed by Bjørn
Erik Edvardsen allows the T750 to deliver maximum performance under
virtually any circumstance, independent of the loudspeakers it is driving.
The circuitry automatically recognizes the impedance characteristics of the
loudspeaker and will then adjust its power supply settings to best cope with
that specific load. This also gives it an unusual characteristic compared to
traditional amplifiers when measuring its continuous output power; the
RMS output power remains the same at 50 Watts with either an eight or a
four ohm load. This is not unusual for NAD however.
NAD takes a stance to the mindless “brochure power” approach which
doesn't give a realistic indication of an amplifier's true capabilities. Instead,
the ISC topology is a practical approach to enable an amplifier to easily
deal with dynamics and difficult loads. More meaningful are the T750’s
dynamic capabilities; up to 160 Watts into 2 ohms and up to 40 amps
current capability.
As one would expect from any NAD component, the Model T750 offers
great flexibility; 4 video, and 4 audio inputs allow you to connect all your
sources with ease.
Hooking up a DVD player with digital surround is a snap with the provided
5.1 input, making the T750 compatible with all surround formats, both
current and future. With pre-amplifier outputs for all channels you can
easily upgrade your output power too.
To ensure long-term contact reliability, all speaker terminals are of the
robust binding post variety rather than the usual spring clips and all other
audio sockets are gold plated.
The remote control handset supplied with the Model T750 also has
controls for NAD CD players or changers and a (dubbing) cassette deck.
With NAD Link it is possible to remote control other NAD products which
do not have their own remote control (NAD Cassette Deck Model 616, for
instance) from the T750’s remote control.

Ease of use is another key factor for NAD products and the Model T750 is
no exception. The built-in test tone generator - accessible by remote control
- allows for accurate calibrating of the Front, Center and Surround
speakers.
Thirty presets can be programmed at random with either AM or FM
stations. Three banks of 10 stations means you can organzize the presets to
personal perference or program type.
complicated, the engineers concentrated on perfectng the Dolby Pro Logic
decoding and steering. For music the Hall mode can be engaged, adding a
natural level of reverberance and life.
In keeping with the NAD tradition, the Model T750 provides performance,
simplicity and value which is hard to match. This new addition to the NAD
line of products is equally at home in a system for discerning music lovers,
as it is in a system for those looking to get the best out of Dolby Surround
Laser Discs, Videos and Compact Discs.

Stadium, etc.) which makes so many other receivers cluttered and over
