¶ What is OPSODIS?
Treble
Bass Bass
OPSODIS (Optimal Source Distribution) is a new virtual surround technology developed
by the Institute of Sound and Vibration Research (ISVR) and Kajima Corporation.
OPSODIS technology has been united with Marantz’s high-quality sound technology
to realize a superior surround environment than ever before.
The ES7001 realizes reproduction of omni-directional sound only with the speakers
built in this unit.
The ES7001 releases listeners from the conventional surround environment that has
required complex installation of five or more speakers. As a result, installing the AV
system in a room has little effect on their lifestyle or living environment.
[DIGITAL AMPLIFIER SECTION]
The unit incorporates a 6-channel digital power amplifier, allowing direct drive of the
speakers’ tweeter, midrange and woofer.
The digital audio signals are input to the digital amplifier of the unit through the optical
digital and the HDMI connectors without digital-analog conversion.
[PWM PROCESSOR SECTION]
Using digital filters for cutoff frequency of the 6 channel digital power amplifier enables
extreme filter precision that cannot be achieved with conventional analog filters,
providing the OPSODIS effects more efficiently.
[POWER SUPPLY SECTION]
The R-core transformer is adopted for the power supply section of this unit. Thanks
to the features of the R-core transformer—less leakage magnetic flux, less heat
generation and quick response to overload variation—the unit produces a high quality
and powerful sound.
[CABINET]
Adoption of high-rigidity aluminum for the cabinet of the unit provides a sophisticated
stiff construction, allowing reproduction of beautiful crystalline sound.
[OTHER FEATURES]
¶
The OPT IN and HDMI IN connectors are compatible with Dolby Digital 5.1ch, dts
and AAC audio inputs.
¶
Supports Dolby PL II feature for 2-channel signal input and for digital signal input.
¶
Binaural recording* sources can be reproduced through the front speaker.
* Binaural recording is a method of recording audio which uses two microphones mounted in the ears of
a dummy head in the shape of the human head and ears.
Binaural recording can reproduce location of sound behind, ahead, above and below. It makes you feel
a real sense of distance.
Normally, a dramatic binaural effect can be achieved only with headphones.
However, a similar or more stereophonic effect can be achieved by playback of a binaural recording
source using this unit than that with headphones.
