TECHNICAL GLOSSARY

AUDIO TECHNOLOGY

3-STAGE AMPLIFICATION

The 3-stage amplification concept offers an extremely wide frequency range needed

for the high resolution formats like SA-CD and DVD-A. In addition it influences the

overall performance in relation to speed and accuracy. The first amplification stage is

built into the pre amplifier followed by a voltage amplification and the 3rd and final is

the power output stage to guarantee high current output driving speakers more vividly

and dynamically.

AUDYSSEY

Audyssey is an acoustic measurement technology which equalizes the acoustic

distortion caused by the acoustic behavior of a room. When you experience Audyssey

equalization, a cloudy layer is lifted away, leaving only clear, accurate, natural sound.

Voices and dialog become focused and intelligible. Musical balance is restored.

Musical instruments and sound effects become precisely localized. Surround

soundstage is made seamless and enveloping. And the best at least, everything will

be done fully automatically with a high quality microphone and a sophisticated audio

processing technology started via the setup menu of the AV-Receiver.

CHOKE INPUT TOPOLOGY

In the power supply section, the choke input topology is adopted to drastically reduce

rectifier harmonic noise. This system is especially suitable for a control amplifier in

which very small signal amplification occurs.

COPPER PLATED CHASSIS

A copper plated chassis provides the best shielding against noise or electromagnetic

distortion radiating from other components in the equipment. It prevents this noise

from being amplified together with the audio signal.

COPPER SHIELDING

Some section of a player or amplifier might produce high frequency distortion or

electro-magnetic radiation. To eliminate this negative effect cousing signal distortion

we add in certain products additional copper shielding to protect the sensitive areas or

parts, improving the overall sound quality.

CURRENT FEEDBACK

"Current Feedback amplification is a well known, Marantz’ original circuit technology.

The Current Feedback amplifier technology fits perfectly with the high requirements

set for Super Audio software providing wide-bandwidth, high-speed reproduction.

The impedance at the Current Feedback point is limited resulting in a very low phase

shift. Marantz receivers and amplifiers equipped with Current Feedback can keep the

phase compensation via Negative FeedBack (NFB) to a minimum, resulting in high

through-rate, excellent transient response and superb sonic transparency for the full

bandwidth. Unlike conventional Voltage Feedback amplification, the Current Feedback

amplification makes the power amplifier in-sensitive to difficult loudspeaker loads.

CUSTOMIZED COMPONENTS

On paper an electrical component might look excellent but the result may fall short of

the combined design expectations. Marantz selects the appropriate components for

the specific design application. In some 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 in close cooperation with the Marantz engineers.

DIGITAL AUDIO BROADCASTING (DAB)

DAB is a digital radio system. It offers near CD-quality sound, more stations, additional

radio and data services and therefore wider choice of programs, the ease of tuning and

interferencefree reception for the listener, plus the information potential of data,

graphics and text. DAB is broadcast on terrestrial networks, and you are able to receive

it using solely a tiny nondirectional stub antenna.

DVD-AUDIO

DVD-Audio is a music format that takes advantage of the high storage capacity of the

DVD to present high quality audio up to six channel. For six channel amplification, DVD-

Audio provides the possibility to have 24bit-96kHz audio information for all six

channels, which results in an increased dynamic range (144dB) and an increased

frequency range (0-96kHz).In a two channel amplification, DVD-Audio expands the limit

of the sampling rate to 192kHz.

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.

HYPER DYNAMIC AMPLIFIER MODULES (HDAM)

"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."

IEEE1394

The IEEE 1394 easy-to-use and high-speed bus easily handles multimedia bandwidth

requirements and provides an universal interface for a variety of devices. This digital

connection ensures that digital data streams of high resolution formats like SA-CD and

DVD-A, are transferred without changing the integrity of the digital signal for both

multichannel and stereo.

LINEAR VOLUME CONTROL

Linear volume control offers minimal cross talk with a very precise volume adjustment

over a range from 0dB to 100dB with a gang error less than +/- 0.5dB.

MARANTZ ROOM ACOUSTIC CALIBRATION (MRAC)

Based on our room acoustics knowledge and expertise already shown in previous

products the Marantz Room Acoustic Calibration (MRAC) was developed. Taking into

account reflections from walls, ceiling and floor and our knowledge about psycho-

acoustics, MRAC optimizes the sound for the room acoustics. With a supplied

microphone placed on your listening position, a powerful DSP analyzes accurately and

sets the sound configuration for your listening room fully automatically. MRAC can

tests and controls speaker configuration, speaker size, trim and distance/delay.

MRAC ADVANCE

The MRAC advance is the extended and optimized version of the MRAC. The MRAC

advance comes along with a 9-band equalizer for an optimized frequency response.

SUPER AUDIO CD

Super Audio CD (SA-CD) is a next generation of music format that provides a more

natural, ultra-high quality sound. It offers a smooth migration path to a higher quality

sound, as all existing CDs can be played on the SA-CD player. SA-CD is

based on the Direct Stream Digital (DSD) technology, which uses 1 bit delta-sigma

modulation and a sampling frequency that is 64 times higher than that of the CD.

This enables the SA-CD to offer a frequency range up to 100KHz and a

dynamic range of 120dB.

SUPER-RING TRANSFORMER

Super-ring transformer has the same advantage with a toroidal transformer such as

high efficiency, stability, and speed. In addition the super ring transformer outperforms

the toroidal transformer on certain aspects. Thanks to its round shape of the core, the

super ring transformer's electro-magnetic radiation and mechanical vibration are

extremely low.

SYMMETRICAL CIRCUIT LAYOUT

To achieve the best possible sonic performance, signal paths need to be short, direct

and mirror imaged. The construction of our circuitry provides improved stereo imaging

by ensuring close to perfect symmetry between right and left channel layout.

TOROIDAL TRANSFORMER

Toroidal transformer has several advantages over a normal EI core transformer. It is

very efficient and therefore delivers more power compared to the same size of an EI

core transformer. In addition, due to its shape, the electromagnetic radiation and the

mechanical vibration are extremely low.

ZERO IMPEDANCE MATCHING JOINT

Improves the signal to noise ratio significantly by adding a copper plated bracket across

the output terminals of the player providing the best ground contact possible.

VIDEO TECHNOLOGY

DCDi

The DCDi (Directional Correlation De-interlacing) technology by Faroudja improves the

video image by using new motion adaptive de-interlacing without introducing motion

artifacts and jagged edges. This circuit provides edge and detail enhancement without

the deleterious side effects.

DVB-T

This product is equipped with a DVB-T tuner. Digital Video Broadcast - Terrestrial is

transmission of digital video information through the air. The video signals can be

compressed by MPEG1 or MPEG2 codec. Benefits of DVB-T are video quality up to

DVD level and audio quality up to CD level. Further nice and useful feature are subtitle

and EPG. EPG is the electronic program guide offering full information on the current

broadcasting and even for one week in advance not to miss any important movie, sport

event or the latest news. In the area where distributed a small antenna is even enough

to receive the broadcasting. No need of a satellite dish or a large antenna.

DivX

DivX is a video compression tool developed to exchange film content via the internet.

With a DivX certified DVD player it is easily to take digital video from the computer and

play it back on the normal TV at almost DVD quality. Thanks to DivX technology’s

superior compression, hours of DVD-quality video can be saved on a single CD. The

latest improved version is called DivX 6.0. The new DivX offers enhanced multimedia

and interactive features such as subtitling, DVD-esque video menus and chapter

points. Video files created in the new format are handily identified by a new file

extension, divx. Please check capability per product in the specification section.

HDMI CONVERSION

Video conversion from analogue level to the digital level for output via HDMI offers

ease of use and best digital picture quality. The analogue signal will be converted one to

one without any further processing. This means interlace analogue signal will be

outputted as interlace digital signal - 576i > HDMI 576i. For analogue progressive signal

the digital output will be progressive as well 576p > HDMI 576p. Please check

compatibility of the TV set or display.

HDMI CONVERSION WITH IP PROCESSING

Video conversion from analogue level to the digital level for output via HDMI offers

ease of use and best digital picture quality for each source material. A one to one

analogue to digital conversion might cause some problems in daily use, because

interlace video signals like 576i will be outputted as 576i digital, but some today's TV

sets can't understand this signal. To avoid problems an IP-processing is applied,

changing the signal from interlace to progressive - 576i will be processed into 576p.

This signal will be easily understand by each TV set.

HDTV ready

HDTV ready products ensure that they are capable of handling HD (high definition)

content with the full resolution. Therefore the requirements are a native resolution of at

minimum 720 lines, a 16:9 aspect ratio, component video input with 720p & 1080i

(50Hz/60Hz) handling and DVI or HDMI digital input with HDCP (high definition content

protection). HDTV ready guarantees full enjoyment of high definition video.

HIGH-DEFINITION MULTIMEDIA INTERFACE (HDMI)

HDMI combines high-definition video and superb audio in a single digital interface with

a bandwidth of up to 5 Gigabits/ second. HDMI1.0 complies with High-bandwidth

Digital Content Protection (HDCP) technology protecting high-value content from

unauthorized reproduction and distribution. HDMI1.0 is the only interface in consumer

electronics that can carry both high-definition video and multi-channel audio e.g. Dolby

Digital and DTS) in all HD formats, including 720p, 1080i and even the upcoming

1080p. With only a single cable connection all information can be digitally transmitted.

The HDMI1.1 is able to transport the high resolution DVD-A data as well. With HDMI1.2

the transmission of high resolution stereo and multichannel information of SACD

completes the portfolio.
