5. nels are capable of putting out an equal amount of power As usual with NAD the T760 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 moderately difficult speakers The NAD T760 uses the new Impedance Sensing Circuitry ISC topology patent pending designed by Bjgrn Erik Edvardsen ISC The ISC topology allows the T760 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 The benefit of this innovative design is that distor tion remains low not just with test tones in the lab but also when playing real music through real loudspeakers 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 1760 s dynamic capabilities up to 200 Watts into 2 ohms and up to 40 amp
6. s peak current capability Whereas it is widely accepted with CD players that the digital and analog cir cuitry play a vital role in the performance it appears that many AV receivers employ only mediocre Digital to Analog DAC Analog to Digital ADC converters and Digital Signal Processors DSP For the T760 the engineers have chosen the best available within the budget Crystal Sigma Delta DACs and ADCs each with 24 bit resolution The DSP chip that handles the Dolby Digital DTS Dolby Pro Logic and EARS Modes is also from the well renowned manufacturer Crystal The combination of these components ensure that the integrity of the original signal be it music or an action movie retains its full resolution and dynamics Flexibility As one would expect from any NAD component the Model T760 offers great flexibility the 5 video 1 on front panel for easy connection of game console or camcorder and 2 audio inputs allow you to connect all your sources with ease Three of the video inputs are full S Video and Composite compatible Besides these normal inputs the T760 also sports an external decoder 5 1 channel input so you can easily expand your receiver in the future with an outboard decoder for another surround sound format 3 Digital inputs are provided to cater for every eventuality Two coaxial digital inputs and a TOS Link for sources with optical outputs With pre amplifier outputs for all channels Left Centre Right Le
