proprietary thinking techno lo gicalbreakthroughs unsur pa ssedspecific at ions the three key elements of nad s master-class engineering for many companies today advanced engineering is the goal it represents a crowning level of achievement once attained it is coveted but nad s design team views it quite differently they are not one to relinquish their ambition even in the celebration of a great accomplishment nad sees the most advanced engineering not as an end point but as a brand new starting line it represents a challenge to see how much further nad designers can go this assertive philosophy shaped the new masters series before pen was put to paper it was determined that this new component series would be `breakthrough small wonder then that it s become a shining example of proprietary thinking technological breakthroughs and unsurpassed specifications these three elements define a new more challenging level of engineering nad s masterclass engineering this brochure details all

m 1 5 surroundsoundpreampprocessor from the mind of the famed master engineer bjorn erik edvardsen sonic detail that you thought never existed music first peformance great performance is expected at this price level yet nad s fanatical attention to every sonic detail is obvious from the very moment the performance begins innovative circuit type and every surround format thx ultra 2 post-processing adds the last word in cinematic realism to your movies and nad s renowned ears uses your surround speakers to `reveal the concert hall in your favorite stereo recordings without adding artificial artifacts the soundtracks of the world s greatest movies are rich with musical content a simple convenience optimum flexibility the surround preamp processor serves as the `brains of your surround sound system it takes the raw unprocessed digital audio signals decodes them into multiple 5.1 6.1 or 7.1 analog channels and sends them on performance be it musical or cinematic the m15 allows the

them completely separate any possible cross contamination is prevented modes direct access to the subwoofer center and surround speaker levels without calling up menus allow for `on-the-fly adjustments cost of this configuration unprocessed analog inputs whether stereo or via the 7.1 input remain in the analog mode sometimes known as `bypass mode if a digital processing mode is selected these signals are digitized using a 128x over-sampling sigma delta adc that employs a linear phase digital anti-aliasing filter to prevent any trace of ripple in the audio band this superb quality adc operates at 192mhz and full 24 bit resolution super high-speed 8 mhz band width low distortion 0.00008 thd amplifiers are use for analog input and output buffers these the m15 can easily handle today s high resolution video signals with support for most analog and digital video formats professional quality video buffer amplifiers feature 150mhz open loop bandwidth with super low phase shift and

m 2 5 sevenchannelpoweramplifier suddenly you become the master of new levels of power for a cleaner sound a minimum of 160 watts per channel proves it massive power more power is always better when it comes to sound quality power is required not only to play loudly but also to play cleanly without audible distortion when an amplifier is asked for more power than it was designed to deliver it can only respond with distortion fortunately the m25 is one of the most powerful amplifiers on the market today designed for home use with a minimum of 160 continuous watts per channel all channels driven simultaneously from 20hz to 20khz at rated distortion of 0.03 the m25 easily delivers lifelike sound levels even in large home theatre rooms it handily meets thx s most stringent certification level ultra 2 unlike most surround sound receivers nad s own receivers are a rare exception that only rate power with 1 or 2 channels running or use very short term measurements the m25 can deliver its

t heinsidestory superb build-artistrytm and a highly refined industrial design set these components apart from all others powerdrivetm provides high dynamic power and low impedance drive capability for explosive dynamics even under demanding speaker loads holmgren custom-made transformers use special steel cores and winding techniques for excellent mains regulation and dynamic performance selectable nad soft clippingtm prevents amplifier clipping distortion proprietary wave heatsink has 34 more surface area then conventional straight fin designs for more effecient cooling unique signal tracking fan circuit keeps the the amp cool and turns the fan off during quiet passages m25 s seven channels are contained in `monoblock gain modules you benefit with the lowest distortion and widest channel a custom vibration damping foot comprised of a cast aluminum support with a highly absorbent silicon rubber insert provides superior vibration resistance separation differential class a input

m 3 dualmonointegratedamplifier noise and distortion aren t infinitesimal as in other high-end amplifiers they re more like non-existent analog sound digital control the m3 is nad s concept of the ideal musical companion capable of transporting the listener to that place where the music simply exists in its own perfect space for this task we have pushed classical analog circuit design to unprecedented levels of performance the total lack of audible noise and distortion is the result of some very sophisticated analog engineering and rather surprisingly the use of digital control freed of the constraints of traditional analog switches nad s director of advanced development bjorn erik edvardsen devised an architecture using precision 1 resistors controlled by digital switches for all the level adjustments required for volume control balance control and tone control yes we still believe in tone controls ­ more on that later input selection is via precision controls in the most

master-class engineering ­ a synthesis of digital analogue and software design has resulted in a series of models that excel in every performance catagory theinsidestory true dual monaural design maintains over 80 db of channel separation under the most demanding operating conditions sealed reed relay switches for superb signal integrity powerdrivetm provides high dynamic power and low impedance drive capability for explosive dynamics even under demanding speaker loads special nad class a gain modules provide tremendous dynamic headroom and nearly immeasurable distortion proprietary distortion cancellation circuit for vanishingly low distortion nad s proprietary multi-stage discreet volume control circuit provides precise volume settings in 0.5db increments with ultra high signal-to-noise ratio a unique vibration damping foot comprised of a cast aluminum support with a highly absorbent silicon rubber insert provides superior vibration resistance gold plated copper buss bars maintain

m 5 5 digitaldiscplayera catastrophe for ordinary dvd players well the ability to decode all formats is only the beginning universal playback with the proliferation of different optical disc formats most people want just one player that will play them all the m55 is capable of playing most all the popular entertainment oriented optical disc format including the high resolution dvd-audio and sacd music formats mp3 and wma compressed formats are also decoded offering surprisingly good sound quality when recorded at higher available bit rates your existing cd collection is also in for a major sonic upgrade when played back through the advanced electronics of the m55 dvd-video can be watched in normal interlaced mode or in progressive scan mode providing your tv monitor supports this type of signal if you have a high definition hdtv monitor equipped with hdmi inputs that support hdcp encryption you can also take advantage of the faroudja dcdi chip that will `upconvert standard dvd 480
