Inputs and Outputs
Amplifier Section: The Marantz SR4003 A/V Surround Receiver
features an 80 watts x 7-channel all discrete amplifier. All
seven amplifier channels mount on an in-line array for even heat dissipation. It
also employs a massive EI power transformer in combination with oversized filter
capacitors. This design configuration is capable of a clear and powerful
reproduction of the most demanding action movie soundtracks and full range
multi-channel music discs. Through its ability to generate very high output
voltages, the unit can easily drive the most demanding speaker with optimum
Independent Power Supply Circuits: Independent power supply circuits
are incorporated for the receiver's FL display, audio and video sections for
maximum separation, clarity and dynamic range.
Digital Signal Processing (DSP): The Marantz SR4003
incorporates an advanced 32-bit digital signal processing circuitry, along with
Crystal 192 kHz/24 bit D/A converter in each of the unit's 7 channels for
exceptional sound quality. The 192kHz sampling and 24-bit word length
capabilities of the DACs allows you to play
high-resolution recordings and hear the increased clarity, detail and dynamic
range of those recordings.
S-Video Up/Down Conversion: The SR4003 can take an analog
S-video input and up-convert it to Component video or down-convert it to
composite video so any S-video signal can be passed through the receiver's
component or composite video monitor output terminal to your television.
Surround Speaker System B: The Surround Speaker B system is a function
of the receiver which allows you to listen to the same audio source in a room other
than the room in which the receiver is located by connecting a pair of speakers
to the Surround Back/Speaker B terminals of the receiver. This feature is only
available when you have no Surround Back speakers connected to the SR4003. The
receiver will be limited to 5.1-channel surround when you have a pair of
speakers connected to the receiver in another room.
AM/FM Tuner: The Marantz SR4003 features a built-in AM/FM
tuner which can automatically or manually store up to 50 AM/FM presets that can
be labeled and viewed in a channel list.
Marantz Room Acoustic Calibration (MRAC): Using
internally generated test signals and proprietary algorithms, MRAC analyzes the
acoustic qualities of your room and automatically determines your speaker
configuration and capabilities, adjusts channel levels and delay settings, and
corrects for virtually all room anomalies through the supplied external
Manual Speaker Setup: You can also manually setup up your
speaker configurations. You can select the size and presence of each speaker,
the distance of each speaker from your normal listening position, and the level
of each speaker in your system.
Surround Modes: The SR4003 is equipped with various surround modes to
reproduce a variety of surround sound effects, according to the content of the
source to be played. The receiver features Dolby Pro Logic IIx, Dolby Digital,
and DTS decoders.
- Auto: When this mode is selected, the unit determines whether the
digital input signal is Dolby Digital, Dolby Digital Surround EX, DTS, DTS-ES, DTS 96/24, or PCM audio.
- Source Direct: In the Source Direct mode, the tone
control circuit and bass management configuration are bypassed for
full-range frequency response and the purist audio reproduction.
- Pure Direct: The Pure Direct mode further reduces sources of
noise in addition to effect of the Source Direct mode, by blocking output
from the video jacks and turning of the unit's display.
- Stereo: This mode bypasses all surround processing. In stereo
program sources, the left and right channels play normally when PCM audio or
analog stereo is input. With Dolby Digital and DTS sources, the 5.1 channels
are converted to two channels stereo. 96kHz PCM source material can be
played back in stereo mode.
- HDCD: When listening to HDCD recordings, you hear more
dynamic range, a focused 3-D sound stage, and extremely natural vocal and
- Virtual: This mode creates a virtualized surround sound
experience from a two-speaker playback system playing any multi-channel
- Multi-Channel Stereo: This mode is used to create a
wider, deeper and more natural soundstage from two channel source material.
This is done by feeding the left channel signal to both left front and left
surround speakers and the right channel signal to both right front and right
surround speaker. Additionally, the center channel reproduces a mix of the
right and left channel.
- Circle Surround II (Cinema/Music/Mono): Circle Surround is
designed to enable multi-channel surround sound playback of no-encoded and
multi-channel encode material. Backward compatibility provides listeners
with up to 6.1 channels of surround performances from an entire collection
of music and film, including broadcast, video tape, and stereo recorded
music. Depending on source material , you can select Cinema, Music or Mono
mode. Circle Surround also offers the following parameter adjustments.
- TruBass: TruBass produced by your speakers is an octave below
the actual physical capabilities of your speakers adding exciting, deep
- SRS Dialog: This feature allows dialogue to easily be
discerned from the surround audio effects.
- Dolby Headphone:
This mode simulates the waveforms of the actual
sounds heard from the speakers when listening to the receiver's audio
through a connected pair of headphones.
- Dolby Pro Logic IIx: Pro Logic IIx expands any existing stereo-
or 5.1-channel audio for a 6.1- or 7.1- channel playback, creating a
seamless, natural surround sound-field that immerses you in the
entertainment experience. Dolby Pro Logic IIx has 5 modes:
- Movie: This mode provides 6.1 or 7.1 channel surround sound
from Dolby Surround, encodes stereo movie soundtracks.
- Music: The Pro LogicIIx-Music mode creates a rich and
enveloping ambience from stereo sources such as CDs. In this mode, the
SR4003 includes three controls to fine tune this sound-field.
- Panorama: Panorama wraps the sound of the front left and
right speakers around you, for an exciting perspective.
- Dimension: This feature adjusts the sound-field either
towards the front or towards the rear of your system. This can be
useful to help achieve a more suitable balance from all the speaker
with certain recordings.
- Center Width:
The Center Width feature allows you to
gradually spread the center channel sound into the front left and
- Game: This mode restores the impact low-frequency surround
effects by routing them to the system's subwoofer.
- Dolby Digital:
Dolby Digital is a 5.1 multi-channel digital
- Dolby Digital EX:
Dolby Digital EX is a 6.1
multi-channel digital surround format.
- DTS Digital Surround: DTS Digital Surround is a 5.1
multi-channel digital surround sound format used for both
commercial/theatrical and consumer grade applications.
- DTS-ES Extended Surround: DTS-ES features two 6.1
multi-channel formats: DTS-ES Discrete 6.1(6.1-channel discrete digital
audio format adding a surround back channel to the DTS digital surround
sound) and DTS-ES Matrix 6.1 (discrete 6.1 channel digital audio format
inserting a surround back channel to the DTS surround sound through matrix
- DTS Neo:6 Surround:
DTS Neo:6 is a matrix decoding
technology for achieving 6.1-channel surround playback with 2-channel
sources. You can choose from two DTS Neo: 6 Surround formats - Neo: 6 Cinema
and Neo: 6 Music. You can also adjust the Center Gain to expand the sound
image from the center channel.
- DTS 96/24: DTS 96/24 is a digital audio format enabling
high sound quality playback in 5.1-channels with a sampling frequency of 96
kHz and 24 bit quantization of DVD-video.
Bass & Treble: You can adjust the receiver's Bass and Treble

included in the Dolby Digital signal or the DTS signal. You can select from 0 to
HT-EQ: The tonal balance of
a film soundtrack will be excessively bright and harsh when played back over
audio equipment in the home. This is because film soundtracks were designed to
be played back in large movie theater environments. Activating the receiver's
HT-EQ feature when watching a film made from movie theaters corrects this and
restores the correct tonal balance.
