The T975 employs monoblock construction for each of its seven channels. Except for the power supply, every element of each channel's circuitry is fully independent, 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, along with a high-current output-stage design, employing high speed, high current 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. Individual gain adjustment for each channel promotes easy, accurate system configuration, as does the T975's integral 12V trigger turn-on response. This multi-channel amplifier delivers its output via heavy-duty "five-way" connectors. Ruggedness and in-system reliability are critical to successful home theatre systems. The T975 uses a unique variable speed fan cooling system first introduced on the M25 Masters Series amplifier, which allows the T975 to deliver massive amounts of power for hours on end. Many lesser amps thermally protect and cycle on and off when asked to perform at their maximum causing an unpleasant disruption of the movie. While a well designed forced air system can eliminate thermal cycling, it is crucial to keep the noise of the cooling fan from intruding itself -- especially during quiet passages of the movie or music. To this end, NAD has developed a unique circuit that measures not only the temperature of the heat sinks, but also the level of the input signal automatically silencing the fans during quiet passages.
