Marantz AV7005 manual Compromise, F E R E N C E S AC D P L a Y E R

NO

COMPROMISE

The SA7S1 is truly a no-compromise piece of engineering. It is the Marantz flagship Super Audio CD Player and it provides the superb sound quality that the SC7S2 and MA9S2 deserve. It follows the legendary SA1 (1999-2002) and CD7 and incorporates key features from both, retaining the excellent SACD playability and customised digital filter technology for CD players – first seen in the CD7.

In addition, because Marantz more than ever is totally committed to unsurpassed quality reproduction we gave the new SA7S1 an unsurpassed treatment in terms of extreme engineering and the utmost attention to detail.As you would expect from such a prestigious piece of work, it features a solid base cabinet, large ring transformer, and copper plating.

NEWLY DEVELOPED ORIGINAL DISC LOADING MECHANISM

As proven by our digital filtering technology: when the market is short in top-quality solutions our engineers develop their own. That’s why we developed the Marantz mechanism SACDM-1 (Super Audio Compact Disc Mechanism 1). Its die-cast construction uses micro precision metals to guarantee the best and cleanest data read-out ever, even on the high speed rotating SACDs. The metal tray is coated with a non-reflecting material to prevent light reflection, which may trouble the laser light. And thanks to the solid-as-a-rock metal body there is no chance of vibration influence. Only supreme, pure digital signal will emerge to feed the digital filters and the D/A converters.

We proudly present you the ultimate sound machine. Because music matters.

SA7S1

R E F E R E N C E S AC D P L A Y E R

The SA7S1 Super Audio CD Player has launched integration into new heights of stunning, reference-quality excellence. Perfect harmony with the other sections of this integrated player is ensured by our highly advanced D2F – Dynamic Digital Filtering technology,which use the Marantz own filter characteristic. The result is the most detailed and dynamic reproduction ever heard. In addition, and unique to Marantz, is our full separation of digital and analogue sections, this not only separates the digital and analogue power supplies but separates them at ground level as well – thanks to the new GMR (Giant Magneto Resistor) technology – completely avoiding any influence of digital noise on the sensitive analogue. Further options are external clock input and digital phase inverting. And because the whole unit is as ‘solid as a rock’, with a metal tray disc mechanism, copper-shielded chassis, high-grade power supply and best-in-class components, this player represents absolute uncompromising quality, designed, engineered and created for the uncompromising ear.

REFERENCE TECHNOLOGIES

CHOKE INPUT TOPOLOGY

In the power supply section, the choke input topology is adopted to drastically reduce rectifier harmonic noise and to reduce the influence of distortion from the mains power network. This system is especially suitable for a control amplifier in which very small signal amplification occurs.

SHOTTKY DIODES

A Shottky diode is a special type of diode with a very low forward-voltage drop compared to normal diodes. This lower voltage drop translates into higher system efficiency.

Shottky diodes have very fast signal handling, can easily stay higher temperatures and are sensitive very low voltages.

LINEAR VOLUME CONTROL

Linear volume control offers minimal cross talk with a very precise volume adjustment over a range from 0 dB to 100 dB with a gang error less than +/- 0.5 dB.

BTL

A BTL is a possibility to use two amplifiers as one monoraul amplifier. This configuration, in theory quadruples the output power delivery to the speaker and offers better control over it leading to a very control, dynamic and open music reproduction.

WBT

Very high quality speaker terminals made by German speaker terminal specialist WBT who has over 20 years of experience in production of best sounding speaker terminals.

MARANTZ INNOVATIVE D2F – DYNAMIC DIGITAL FILTERING

Some audio companies focus on sound modification by selecting and customising electrical components for the analogue part of the player but they have only limited knowledge of digital filtering and have to use standard solutions – which Marantz believes to be sub-standard for a genuine audiophile player. That’s why Marantz has invested extensively in gaining expert knowledge into this crucial part of a CD player during CD playback. The Marantz Digital Filter eliminates out-of-band noise, reflecting into a better S/N ratio, dynamic range, and various other characteristics. There is no group delay, and the player offers flat frequency characteristics. Filters of three types are provided, and because each affords a distinctive sound, users can switch to the desired filter for playback suiting the disc or their listening mood.

GMR – GIANT MAGNETIC RESISTOR

The Giant Magnetic Resistor is a technology compare able with an optical coupler, makes it possible to separate two section of a product galvanic. The GMR outperforms the optical coupler when it comes to high frequencies. This big benefit is used in this player to separate the digital section from the analogue one and this even on the ground level.

No high frequency distortion to the sensitive audio signal; no influence to the power for the audio stages.

FLOATING CONTROL BUS SYSTEM

A Marantz own communication system to connect pre- or integrated amplifiers over a dedicated bus line to enable synchronized operations. The units are working as master and slave – the master unit controls the others. F.C.B.S. can be used for a powerful bi-amping or a multichannel surround setup.

• Rigid double layer chassis construction with aluminium front and side panels

• Balanced XLR and gold-plated RCA output terminals

• Low noise LCD

• Aluminium-top remote control with Marantz amplifier control
