NOTE: THE NUMBERS BETWEEN ICON AND PRODUCT FEATURE REFER TO THE GLOSSARY COLUMN IN THE TECHNICAL DATA ON THE NEXT PAGES.
1. 70% POWER GUARANTEE
Marantz has the 70% power guarantee, meaning that a minimum of 70% of the stereo power
indicated in the specification section will be available when 5 channels are simultaneously
used. A lot of misunderstanding about power rating has been created by some manufacturers
claiming the highest possible output power as a unique selling point. Measurement often has
been done on only 1 speaker drive, with impedance lower than 8 ohms and a high THD (total
harmonic distortion) acceptance. A standard THD value is 0.08%. The lower the better.
2. 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, Current Feedback amplification makes the power amplifier
insensitive to difficult loudspeaker loads.
3. TOROIDAL TRANSFORMER
A Toroidal transformer has several advantages over a conventional EI core transformer.
It is very efficient and therefore delivers more power compared to a same-sized EI core
transformer. In addition, due to its shape the electromagnetic radiation and the mechanical
vibration are extremely low, which minimizes interference and maximizes sound quality.
4. HYPER DYNAMIC AMPLIFIER MODULE (HDAM)
Marantz developed its own discrete circuit boards to replace standard ICs.
These replacements circuit boards are called HDAMs and consist of discrete surface-mounted
components with short mirror image L/R signal paths. They perform exactly the same function
as the Op-Amps, but outperform the regular IC Op-amps dramatically in terms of the Slew
Rate and reduced noise level, resulting in a much more dynamic, accurate and detailed sound.
Over the years Marantz has developed different types of the HDAM to improve quality and
to fit to the special requirements of specific product categories such as CD and amplifier.
5. 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 Marantz engineers.
6. 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
near-perfect symmetry between right and left channel layout.
7. 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. And even more importantly, it gives equal
low impedance ground level to every point of the chassis, keeping the ground potential as
clean as possible.
8. ZERO IMPEDANCE MATCHING JOINT
This 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.
9. PURE / SOURCE DIRECT / AUDIO EX(CLUSIVE)
Pure / Source Direct / Audio EX are special listening modes that provide the highest possible
signal purity. They can be used for both analogue and digital sources, with two-channel or
multi-channel inputs. When selected, the signal follows the most direct path and does not
pass the tone and bass management circuitry or any DSP (digital signal processor) of either
the AV-Receiver or player pitch control. By minimizing as much processing as possible the
signal is ‘untouched’ and remains very close to the original, thereby minimising distortion.
10. TRITONECONTROL
Marantz extended the sound tuning possibilities by introducing Tri-Tone-Control.
In addition to Bass and Treble you can now also adjust the Mid-Range. This is a big
advantage especially for today’s compressed audio formats like MP3 and AAC.
11. POWER AMP DIRECT
Power Amp Direct enables an integrated amplifier to be used within a stereo set-up or as a
power amplifier within a multichannel set-up. With Power Amp Direct switched off, it acts
as a normal integrated amplifier for perfect sound quality in a stereo set-up. With Power
Amp Direct switched on, it uses the power amplifier for driving the front left and right
speakers within a multichannel set-up, using the surround channels from your A/V receiver.
What’s more, it does all this with a single push of a button, without changing wires.
The Power Amp Direct can also be used for a stereo bi-amping set-up.
12. SUPER AUDIO CD
Super Audio CD (SA-CD) is an established 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 an 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 a CD player. This enables the SA-CD to offer a frequency range
up to 100KHz and a dynamic range of 120dB.
13. DSD AUDIO STREAMING
DSD is a 1-bit digital audio stream which offers high resolution audio in DSD64 (same as SACD
resolution) and DSD128. These are also known as DSD2.8 (2.8MHz sampling frequency) and
DSD5.6. DSD audio files can be downloaded from the internet and stored on a computer.
For playback of the high resolution audio, the PC / MAC should be connected to a USB-DAC
or Player with USB-DAC mode, featuring USB-B connectivity and supporting DSD streaming.
For the transmission of the DSD signal a technology is used called DoP - DSD over PCM.
14. MARANTZ MUSICAL MASTERING
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 or in DAC-Mode
operation feeding an external signal. The Marantz Digital Mastering eliminates out-of-band
noise, reflecting into a better S/N ratio, dynamic range, and various other characteristics.
15. USB AUDIO / USB TYPE B
USB Audio makes it possible to listen to compressed audio files (MP3, Windows Media™
Audio, etc.) stored on MP3 players or external hard discs. All Marantz USB-enabled products
make use of the USB 2.0 profile for fast and stable data transfer. Some products feature the
USB Type B standard. These products can be directly connected to the PC and will be recognized
as an external soundcard. When asynchronous mode is supported, the player’s own clock is
used for data transmission – not the PC’s clock. This guarantees best audio as music stored
on the PC is reproduced via the Marantz product with its high-quality audio output stage.
16. AUDIO STREAMING
Digital media stored on a computer or NAS (network access storage - network hard disc
drive) is becoming more and more popular. But you can only listen to this music via your
portable media player or from your PC – until now. With our products supporting audio
streaming you can enjoy this ‘portable’ music via your HiFi system in high-quality, and while
sitting on your couch. Some products support gapless playback making it possible to stream
live concerts without interruptions between tracks.
17. DAC MODE
Marantz products with a DAC mode can be used as an external Digital to Analogue Converter
(DAC). You can connect via optical / coaxial digital inputs or the USB type B input sources
such as an external CD drive, digital tape, music server, PC or network client. These sources
can make use of the high quality D/A converter and the analogue output stage equipped with
HDAM modules to enrich the sound quality. Please check USB Type B description as well.
18. MDAX2
The use of compressed audio files like MP3, Windows Media™ Audio or AAC is becoming
increasingly popular. However, the audio quality of these compressed files is lower than the
original lossless files on a CD. In particular, the higher frequencies are lost in compression.
This not only reduces the high frequency quality but also =negatively impacts on the lower
frequencies. The result is that the audio image is less wide and less deep. The Marantz
Digital Audio Expander 2, also called M-DAX2, corrects this by recalculating the outputted
frequency range for a more detailed and clearer sound.
19. AUDYSSEY / AUDYSSEY LFC
Audyssey is an acoustic measurement technology which automatically restores the acoustic
distortion caused by the acoustic behaviour of a room with only a push on a button. Audyssey
equalization provides an clear, accurate, natural sound with voices and dialog that become
focused and intelligible, restoring the musical balance. Musical instruments and sound effects
become precisely localized and the surround soundstage is made seamless and enveloping.
Audyssey LFC is a technology to enjoy Late-Night TV and Music without disturbing neighbors.
Audyssey LFC prevents low frequencies from traveling through walls without sacrificing bass
enjoyment. In addition to Audyssey MultEQ the MultEQ XT provides 8x filter resolution as
well as 8 measurement positions vs. 6 postion on the MultEQ.
20. AUDYSSEY DYNAMIC EQ / AUDYSSEY DYNAMIC VOLUME
Dynamic EQ selects the best possible frequency response and surround volume levels
moment-by-moment. This ensures that the bass response, tonal balance and surround
impression remain constant on each volume level. This is a pre-requisite for delivering a
dynamic volume solution. It avoids the irritation of varying volumes between television
programs, commercials and within the program material itself. The Audyssey Dynamic
Volume monitor automatically adjusts and equalises these volumes.
21. 1080P UPSCALING / VIDEO CONVERSION
Upscaling is the process of converting a standard definition (SD) video signal to a seemingly
high-definition (HD) video signal by using a video scalar. Upscaling does not convert standard
definition video to true high definition video, but it does dramatically improve the detail and
colour consistency of the picture, up to 1080p, the resolution possible for HDTV. An AV
receiver 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. This feature allows you
to connect several sources to an AV receiver and run only one cable to the TV set.
22. 4K HD VIDEO
4k is the latest video standard for big screen sizes. The 4k represents the horizontal resolution
of 4096 pixel and often offers a vertical resolution of 2160 pixel. Therefore, 4k has four times
the resolution of HD 1080p. Our products feature the up-scaling of analogue and digital video
signals to 4k resolution. Furthermore, they support 4k source-switching and pass through.
23. HIGH-DEFINITION MULTIMEDIA INTERFACE (HDMI)
HDMI combines high-definition video and superb audio in a single digital interface with a
bandwidth of up to 10 Gigabits/ second. HDMI complies with High-bandwidth Digital Content
Protection (HDCP) technology protecting high-value content from unauthorized reproduction
and distribution. HDMI is the only interface in consumer electronics that can transmit both
high-definition video and multi-channel audio such as Dolby TrueHD and DTS-HD formats,
including 720p, 1080i and 1080p through one single cable.
24. GUI & SETUP ASSISTANT
The Setup Assistant and the Graphical User Interface (GUI) make the initial set-up of our new
AV-Receivers very easy. They also enhance your AV experience by maximising ease-of-use.
The assistant guides you through the complete set-up of your AV receiver with ease and
simplicity, covering the processes of speaker connection, auto speaker calibration, and connection
of source devices - all supported by clearly illustrated on-screen graphics. In daily use, the
GUI really stands out and presents information about volume, surround mode, input source and
more, all on the TV screen in a transparent banner with the film still running in the background.
25. BLU-R AY DISC
Blu-ray Disc, also referred to as BD-ROM, is the next-generation High Definition (HD) optical
disc format. The format has been developed to enable recording, rewriting and playback of
High Definition video and audio which offer consumers an unprecedented high definition
1080p experience, providing an exhilarating life-like image and an audio soundtrack that is
more detailed and clearer than DVD.
26. 3D READY
3D stands for 3 dimensional. Products carrying the 3D logo are able to output or path
through the digital 3D video signal.
27. DI V X U LTR A

whose function allows you to stream digital video files located on any other DLNA prepared
computer or NAS (network attached storage - network hard disc drive) from anywhere within
your home computer network. The result is that the streamed video is displayed on your TV
screen in resolutions right up to 1080p HD (high definition) quality.
29. DOLBY TRUE HD
Dolby TrueHD is Dolby’s next-generation lossless technology developed for high-definition
audio coding. Dolby TrueHD supports up to eight full-range channels, allowing the audio
engineer to position sounds for a more realistic effect than ever before.
30. DOLBY PRO LOGIC llx & DOLBY PRO LOGIC llz
Dolby Pro Logic IIx is a complete surround sound solution featuring Movie and Music mode
that function with 5.1 as well as stereo source material. It delivers a natural and immersing
up to 7.1-channel surround listening experience to the home theatre environment.
Dolby ProLogic IIz is a new listening experience with a more life-like sound stage by using
additional Front Height channels, which add a vertical component to the horizontal sound
field of conventional 5.1 or 7.1 systems. The enhanced spatial effects bring an overall airiness
to the listening experience, and a new dimension of presence and depth.
31. DTS-HD MASTER AUDIO / DTSHD
Master Audio is an optional High Definition Audio format for all Blu-ray Disc™ products.
DTS-HD Master Audio format allows a bit-to-bit representation of the original movie’s studio
master soundtrack and delivers audio at high constant bit rates superior to standard DVDs.
32. DTS NEO:X
DTS Neo:X™ is a comprehensive upmixing solution offering up to 11.2 channels of immersive
surround with near discrete Front-Height and Wide imaging. From ambient/non-directional
effects like raindrops to overhead effects like a low-flying jet, DTS Neo:X lets listeners track
all the audio action. Sound arcs overhead to the Front-Height speakers, sideways to the Wide
speakers, and back to the Rear speakers, creating a semi-spherical soundstage.
33. AUDYSSEY DSX
Audyssey engineers proved that realistic reproduction of surround sound relies on the ability
of audio systems to match human hearing performance. Key requirements are: (1) frequency
response, (2) dynamic range, and (3) accurate spatial rendering. Research has shown that
accurate spatial sound rendering requires more information than a 5.1 surround sound system
can provide. Audyssey DSX delivers this additional information from the required directions to
overcome the limitations faced by 5.1 surround sound systems by adding front height and / or
front wide speakers for the most realistic performance.
34. MULTI ROOM / MULTI SOURCE
With the Marantz AV system placed in the main room of the house, a second or even a third
loudspeaker set can be placed in 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. For example, in the main room, a DVD can be played back
with multichannel surround, while people in a second room can enjoy music from a CD player,
a third room can even have audio and video coming from the connected satellite set-top box
- all at the same time - all independently. The latest top-class AV receivers even offer Zone
Video by HDMI. Please check specification section for number of zones and more details.
35. DBUS
To optimize 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 to be controlled via the Marantz System Remote Controller.
36. 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.
37. IRFLASHER
