Based on the well received SA8400 Super Audio CD Player the SA7001 brings superb audio quality to all music lovers. This is the answers to concerns of audiophiles regarding functional integration of CD playback at the costs of audio quality. This player utilized all the benefits of the SA-CD format in stereo, of course allowing also standard CDs to be played back at high level quality. The SA7001 brings you all the depth, dynamics, and sonic excellence youve come to expect from Marantz finest components. And at a cost that puts the best within the reach of almost everyone. P urit y fo r th e p uris ts Enjoy the fabulous world of high resolution audio! Finally you can have an incredible live-experience in your home as it was in reality. Not only is the total ambiance reproduced, but also the natural 'sound' of the instruments is being preserved. SA-CD is based upon the DSD conversion principle that links excellent specifications like a frequency range of 100 kHz and a dynamic range of 120 dB, to superb sound quality. S u p er A udio p la y b ack The outstanding D/A converter, boasting a successful heritage in high-end machines including the SA-15S1 and SA8400, produces clear sound for Super Audio CDs and regular CDs alike. The CS4397, 'Super DAC', from Cirrus Logic is developed to provide high quality audio output for new standards such as SA-CD. It incorporates Cirrus Logic's mixed-signal technologies, including Switched Capacitor techniques, Multi-bit Delta Sigma Modulator architecture, and Dynamic Element Matching. All this results in an unsurpassed dynamic range and detailed resolution, which are key to a striking SA-CD performance. T he 'S u p er D AC' Audio devices are usually equipped with Op-Amps (operational amplifiers) for which Integrated Circuit (IC) are commonly used. Unfortunately these IC's do not match the very high requirements of Marantz. Marantz developed it's own discrete circuit boards to replace the IC's. These HDAM's consists of discrete surface mount components with short mirror image L/R signal paths. Those devices are doing exactly the same thing as the Op-Amps, but outperform the regular IC Op-amps dramatically in terms of the Slew Rate, resulting in a much more dynamic, accurate and detailed sound, as well as on the signal to noise ratio. The Marantz HDAMs offering very low noise operation. There are no IC OP-amps used at all in the SA7001's analogue signal path. C urre n t Feed back H DAM s The SA7001s analogue audio circuitry is a full discrete design including newly developed Current Feedback HDAM modules that operates as a buffer amplifier and as a Low Pass Filter. Both channels are completely identical in terms of components and circuit layout. This is extremely important to be able to enjoy a breathtaking sound stage of stereo SA-CD material. Every Marantz product is designed with a fine ear and eye for details. The designers have to know the characteristics of every component. On paper the component might look excellent but the result may fall short of the combined design expectations. Therefore Marantz collects vast amounts of information upon specifics component performance capabilities. Marantz selects the appropriate components for the specific design application. The sonic result is then critically acclaimed by international reviewers. In other cases it's simply not possible to use standard components that meet the high Marantz standards. These components will then be specially made for Marantz only in co- operation with the Marantz engineers. C usto m iz e d C om ponen ts The strength of each Marantz design can be found in the attention to detail and cohesiveness of the different elements. The SA7001 is a clear example of benchmark engineering and craftsmanship and features a number of Marantz sound enhancements. The SA7001 SA-CD player is built on a solid metal chassis. Extensive bracing and shock-absorbing feet result in minimized internal vibration and mechanically induced jitter. All of the digital, analogue and control circuits are separated and shielded in their own enclosures to prevent cross-talk and other unwanted interference. Independent power supplies for each dedicated system block secure maximum separation, clarity and dynamics. Symmetrical lay out hand-selected Customized Components, gold-plated terminals and the renown Marantz Current Feedback HDAMs all work in harmony. This design configuration is capable of a 'live experience' reproduction of the most complex music pieces composed. A to uch o f M ara n tz For the headphone listeners we have paid extra attention to the headphone circuitry to ensure that the pure emotion of SA-CD is passed on. A dedicated amplifier is developed with a fast current-buffer amp, constructed of discrete components only, including a high grade potentiometer for the volume control. P ers o nal en jo ym en t

We've taken advantage of insight from all past Super Audio CD player development to create new mechanism modules specifically for audio applications. The servo and decoder are mounted on a four-layer glass epoxy board. Noise radiation is extremely faint, and shielding is provided by box construction incorporating the chassis, preventing any noise from penetrating inside. The tray is finished with an elegant coating that also dampens vibration, and we've chosen black as an ideal tray and mechanism color or minimal effect on laser diffusion. Pure a u dio m odule s To optimize equipment in terms of ease of use, Marantz has designed the D-Bus system. Individual devices inform each other, in order to automatically tune to the customers demands. At the same time received remote control commands are communicated via this bus. This enables equipment without IR-receiver, like a cassette deck or tuner, to be controlled via a Marantz Remote control. M ara n tz D -B us Every electronic equipment product is built of single electrical components that are made of different material and substances. Marantz assure that the components used in our products are free of any dangerous material or substance to keep our environment clean. We have for example removed hazardous substances like lead in the solder.
