Details
NAD has a well-deserved reputation for producing amplifiers with extraordinary performance and always
at an affordable price. The T975 keeps this tradition alive and well by applying over 30 years of experience
to the challenge of producing a very high power, high performance, seven channel power amplifier able to
provide the musical muscle required for even the most sophisticated Home Theaters.
Consumers are often confused about power ratings, with many 'mass market' brands claiming power
output levels that seem too good to be true. These inflated claims quickly fall short at the first listen. NAD's
Full Disclosure Power ratings are the most conservative in the industry, and allow the T975 to handle any
speaker load and any program material. The benefit of NAD's Full Disclosure Power is the total elimination of
audible distortion at any listening level. This provides pinpoint imaging and spine tingling realism with music
and movies alike.
The 7-Channel NAD T975 is a perfect accompaniment to the T175 A/V Tuner Preamplifier.
Design
As might be expected in an amplifier capable of one kilowatt (1,000 watts) of continuous power output, the
power supply needs to be very carefully designed. As usual, NAD favors the toroidal transformer type for its
superior regulation and low stray magnetic field. Our exclusive "Holmgren" transformer uses a special core
design and materials to enhance efficiency and make the transformer less sensitive to DC offsets on the
AC mains voltage. Over 80,000 uF of storage capacitance ensure an ample reserve of power for even the
most demanding music and film soundtracks.
The T975 employs mono-block construction for each of its seven channels. Every element of each channel's
circuitry, save the power supply, is fully independent thus eliminating inter-channel influences as a concern.
The T975 employs active ground isolation to further eliminate any possibility of inter-channel interference
even when more than one preamplifier is driving the power amp (as might be the case in a custom installation).
Each section features an FET Class A input and driver stage circuits, and a high-current output-stage design,
employing high speed, discrete output devices to promulgate superb dynamic quality. The result is musical
detail, impact, and soundstage stability and depth unmatched by multi-channel amps of even two and three
times the T975's price. NAD's proprietary Soft Clipping™ (defeatable) maintains sonic quality and offers
speaker protection even under severe overdrive conditions.
Individual gain adjustment for each channel promotes easy, accurate system configuration, as does the
