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.

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.

DAC

Digital-to-analog converter. Circuitry that converts digital data (such as audio or

video) to analog data.

DCDi

The DCDi (Directional Correlation De-interlacing) circuit 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 dele-

terious side effects. These chipsets have been chosen for their 10-bit processing of

video images as well as their incredible flexibility.

DOLBY DIGITAL EX (DD EX)

Dolby Digital EX brings a dimension of depth, spacious ambience and sound local-

ization to home theatre environment. The benefits of DD-EX include more realistic

flyover and fly-around effects from an additional rear center speaker (6.1), providing

a more stable image for atmospheres and music and a more consistent surround

effect throughout the auditorium or home viewing area.

DOLBY HEADPHONE

Dolby Headphone technology allows users to listen to music, watch movies, or play

video games with the dramatic surround effects of a 5.1-channel soundtrack through

any set of headphones. Best of all, ‘listener fatigue’, a phenomenon commonly asso-

ciated with headphone playback, is replaced by a spacious, natural sound field that

listeners can enjoy for hours.

DOLBY PRO LOGIC IIx

Dolby Pro Logic IIx is a complete surround sound solution that maximizes the enter-

tainment experience from stereo as well as 5.1-channel encoded sources. Dolby Pro

Logic IIx technology features Movie and Music modes that function with 5.1 as well

as stereo sources, including 24-bit / 192 kHz and 24-bit / 96 kHz sources. Dolby Pro

Logic IIx technology delivers a natural and immersing 7.1-channel listening experi-

ence to the home theater environment.

DTS ES 96 / 24 Neo:6

The DTS-ES surround system offers a superb sound quality and a range of formats.

The Discrete 6.1 offers the ultimate quality of surround field creation, while the

Matrix 6.1 provides compatibility for the existing DTS 5.1 software. And the

Neo:6 is to create 6.1 surround stage from any two channel source. DTS 96 / 24

allows for 5.1 channel sound track encoding at a rate of 96 kHz / 24 bits on DVD-

Video titles. Higher sampling rates provide greater bit depth and allow a wider

frequency response. In conjunction with the use of anti-alias and reconstruction

filters DTS 94 / 24 results in a more transparent sound quality equivalent to the

original soundtrack and is fully backwards compatible at the same time.

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 amplifica-

tion, DVD-Audio provides the possibility to have 24 bit-96 kHz audio information for

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

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

expands the limit of the sampling rate to 192 kHz.

DIGITAL VIDEO INTERFACE (DVi-D)

For high definition all-digital video to look its best, the data must be transferred from

your digital source to your HD display or projector in pure digital form. In order for a

DVD player to do its job, it has to convert video data from the digital domain to

analog, and then back to digital again. This conversion process can cause high

frequency attenuation, and loss of resolution and detail. The DVi-D output is a pure

digital high bandwidth video interface. What you see on your screen is exactly what

was digitally recorded dynamic, accurate and detailed sound.

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.

HIGH-DEFINITION MULTIMEDIA INTERFACE (HDMI)

HDMI assures that pristine high-definition images retain the highest video quality

from the source all the way to the display. HDMI transmits video data digitally with

a bandwidth of up to 5 Gigabits / second. Benefits include uncompressed digital

quality, fewer cables and a small, user-friendly connector suitable for a wide range

of components. HDMI on the Marantz’ products complies with High-bandwidth

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

unauthorized reproduction and distribution. HDMI has been designed to make it

possible to handle the transmission of both digital video and digital audio with a

single connector.

LIP SYNC

The digital processing and scaling of video displays can create a slight delay in the

video signal. This delay makes audio tracks appear out of synch. Using sound delay

(Lip Sync) you can slow the sound presentation to match the presentation of the

video.

MARANTZ ROOM ACOUSTIC CALIBRATION (MRAC)

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

like the AX1000, the Marantz Room Acoustic Calibration (MRAC) was developed. The

algorithms developed are derived from this amazing AV computer developed more

than a decade ago. Taking into account reflections from walls, ceiling and floor and

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.

MRAC can tests and controls speaker configuration, trim, distance / delay and fre-

quency response.

NSV

NSV Precision Video is used for very high-quality picture reproduction. This

technology allows video images to be displayed at resolutions and lower effective

signal to noise ratios well beyond that which would be expected from the data

converter by making use of the latest technological advances. The improvement

takes place in parallel with the simultaneous move to support more and more higher

definition video standards including Progressive Scan and HDTV.

O.R.C.A FILTER

Marantz engineers developed a colour correction filter called ORCA (the Optical

Reproduction of Colour Accuracy), which filters out the excess yellow, creating a

very neutral white light that passes through the colour wheel. This results in the

most accurate colour palette ever achieved in a video projector and has been

balanced to meet the HD colour space (ITU-RBT709). This is an industry first and

a Marantz exclusive!

PROGRESSIVE SCAN

Compared to a conventional interlaced picture, progressive scanning creates a

picture signal with double the scan lines, resulting in a noticeably sharper image.

The progressive image offers higher picture resolution and eliminates virtually all

motion artifacts. Even on large screens, the progressive scan lines are barely notice-

able and picture flickering is greatly reduced, so you can enjoy extended viewing

without eye fatigue.

SRS CIRCLE SURROUND II

Circle Surround II is a powerful and versatile multi-channel technology designed to

enable up to 6.1 multi-channel surround-sound playback from mono, stereo, CS

encoded sources and other matrix encoded sources. CS-II places the listener ‘inside’

the music performances and dramatically improves the separation and image

positioning of both hi-fi audio conventional surround-encoded video material, adding

a heightened sense of realism.

SUPER AUDIO CD

Super Audio CD (SACD) 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 SACD player. Super Audio 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 Super Audio CD to offer a frequency range up to 100 kHz and a dynamic

range of 120 dB.

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 out-

performs 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.

THX ULTRA2

THX Ultra2 incorporates two additional processing technologies: Advanced Speaker

Array (A.S.A.) and Boundary Gain Compensation (B.G.C). ASA is a proprietary of THX

technology which processes the sound fed into 2 surround and 2 surround back

speakers to provide the optimum in enveloping surround sound reproduction. When

placing the 2 surround back speakers close to each other and build your home

theatre setup using 8 speakers, ASA will create the largest possible sweet spot in

your surround sound field. Boundary Gain Compensation provides an optimized bass

balance in case the listening room layout results in most of the listeners being

seated close to the rear wall. This technology prevents a 'boomy' bass yet processes

the appropriate bass reinforcement.

THX Select

THX Select technology delivers all the proprietary THX Home Theater features that

reproduce accurate and stirring soundtrack audio – in a system optimised for smaller

spaces (home environments of 2000 cubic feet or less). Offering this technology in

mid-priced products that delivery top-quality sound, THX Select combines audio

power and integrity with superior economic value.

THX Surround EX

THX Surround EX is the home version of this latest advance in hyper-realistic sound

technology. Available exclusively in THX-licensed 'Ultra' and 'Select' series products,

THX Surround EX decodes a back surround signal from the left and right surround

channels on specially encoded DVD movie releases. Unlike products offering ‘6.1’

channel decoding schemes, only select THX Certified components adhere to superior

performance specifications through redirecting bass energy in the Surround back

channels to the subwoofer, ensuring optimum bass performance, requiring Re-

Equalization™ of the Surround back channels to match characteristics of the front

and left / right surround channels and synchronising the Surround Back Left and

Surround Back Right speakers in time and position relative to the listener, providing

a seamless surround sound experience. The same technical standards for Surround

back channels are maintained for Left and Right channel surround, eliminating com-

promise in channel separation, noise, headroom, bandwidth and decoding accuracy.

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.

VIDEO CONVERSION

It can up convert the Composite signal to S-Video/Component and S-Video to

Component; as well as down convert from S-Video to composite (the component

signal is not down converted). This feature allows you to connect any source via a

single component. In order to avoid synchronization the high quality video converter

is equipped with digital video processing consisting of for example; 4H line memory,

time based corrector, a triple 10-bit DAC, filed locking, VCR detection and anti

aliasing filtering.

VISUAL EXCELLENCE PROCESSING

Gennum’s VXP offers stunning image quality by applying the most advanced image

processing techniques to all SD, HD and graphics signals including content adaptive

de-interlacing of HDTV 1080i signals. The internal adaptive de-interlacer sets a new

standard for motion processing, film mode detection and dynamic directional edge

processing. With its10-bit signal path and high precision processing, VXP enables the

newest generation of display technologies to fully utilize their ability to display 10-

bit grey-scales and colours. Additional Broadcast quality algorithms that include

adaptive noise reduction and detail enhancement remove unwanted noise while

improving image detail for an uncompromised, cinematic High Definition experience.
