Marantz Home Theatre 2007 - Manual (Page 3)

AUDYSSEY
Audyssey is an acoustic measurement technology which equalises the acoustic distortion caused
by the acoustic behaviour of a room. When you experience Audyssey equalisation, 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
localised. 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
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
D-Bus
To optimise equipment in terms of ease of use, Marantz has designed the D-Bus system. Received
remote control commands are communicated via this bus. This enables equipment without an IR
Receiver like tuners or hidden system together with an external IR eye to be controlled via the
Marantz System Remote Controller
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 deleterious side effects. These chipsets have
been chosen for their 10-bit processing of video images as well as their incredible flexibility
DC-TRIGGER
A DC trigger is an assignable voltage output which can automatically control for example an
electrical projection screen, lowering it when the DVD input is chosen on the receiver
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
DOLBY DIGITAL EX (DD EX)
Dolby Digital EX brings a dimension of depth, spacious ambience and sound localisation to home
theatre environment. The benefits of DD-EX include more realistic flyover and fly-around effects
from an additional rear centre 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 associated 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 maximises the entertainment
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 experience 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 amplification, 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
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
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 unauthorised 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
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
IR-FLASHER
The IR-Flasher In is a standardised connection to control the AV system by external IR receivers
independent of the infra red control format used. On the IR-Flasher out a IR Emitter can be connected
to controlled third brand components. The third connection link to this is the IR-Receiver input
which is similar to the IR-Flasher In, but it outputs a voltage to feet an external IR-Receiver eye.
Please check capability per product in the specification section
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 sync. 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 optimises
the sound for the room acoustics. With a supplied microphone placed on your listening position, a
powerful DSP analyses accurately and sets the sound configuration for your listening room. MRAC
can tests and controls speaker configuration, trim, distance / delay and frequency response
MULTI ROOM / MULTI SOURCE
With the Marantz AV system placed in the main room of the house, a second or even a third loud-
speaker set can be placed in two separate rooms. In those rooms an audio and even a video source
can be selected independently from the main room at a different sound level and with full remote
control functionality
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 noticeable and picture flickering is greatly reduced, so you can enjoy extended
viewing without eye fatigue
RS-232C
The RS-232 is a communication port direct to the micro processor of the device. It is possible to
control the component and get status feedback via this connection without any visual contact and
even offers a way to update the system software if needed
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 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
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 optimised 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-Equalisation™ 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 compromise in channel separation, noise, headroom, bandwidth and decoding
accuracy
TRUE HD 1080P
1080p is the short name for a category of video modes. The number 1080 stands for 1080 lines of
vertical resolution, while the letter p stands for progressive scan or non-interlaced. 1080p is the
resolution possible for HDTV. The term usually assumes a widescreen aspect ratio of 16:9, implying
a horizontal (display) resolution of 1920 lines and a frame resolution of 1920 x 1080 or over two
million pixels. 1080p is the digital standard for filming digital motion pictures. Directors such as
George Lucas (in Star Wars: Episode III) shoot their digital films in this high definition mode to be
shown in theatres equipped with 1080p digital projectors. The new projector VP-11S1 applies the
latest DLP chip from TI featuring the resolution of 1920x1080, not to miss any pixel of information
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 synchronisation
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 utilise
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
