You'll enjoy enveloping, 360° surround sound with all of your movies, music, TV shows, and video games. And you get decoding for the latest surround formats, including Dolby® TrueHD and DTS-HD™ Master Audio — two high-resolution formats found on many Blu-ray players and discs.

Three HDMI inputs plus 1080p video upconversion
The SR6003's 1080p-compatible HDMI inputs let you hook up three high-definition sources for easy switching. Two HDMI outputs mean you can route high-def video signals to both an HDTV and a home theater projector. Plus, analog-to-HDMI video upconversion allows you to pass the video signals from all your components to your TV via a single-cable digital connection — even older, non-HD sources. This simplifies hookup and ensures the best picture quality possible for every source in your system.

Precision auto setup tailors sound to your room
Marantz also includes Audyssey MultEQ®, a sophisticated auto-calibration system that helps you get the most accurate home theater sound possible. The SR6003 uses the supplied microphone to analyze sound from up to six different listening positions, then automatically adjusts level, equalization, and delay settings for each of your speakers. The result is accurate response across a wide listening area instead of just a single "sweet spot," so everyone in the room can enjoy precisely balanced home theater sound.

Multi-room music and more
This receiver's flexible multi-room/multi-source output lets you enjoy a surround sound movie in your main room while a housemate listens to stereo music in a second room. You can even send audio from a digital source to a third room via an optical digital output, for playback on another home theater receiver. Add an XM Mini-Tuner package to enjoy satellite radio, including XM's HD surround music channels. Or connect an optional SiriusConnect™ home tuner kit to enjoy SIRIUS satellite programming. You can also get your iPod® into the mix by adding Marantz's handy control dock.

Marantz SR-6003

Dave from Birmingham, AL on 10/11/2009

Crutchfield Customer Review (What's this?)

Great receiver! Setup is a breeze, you almost don't need the manual. Sound is great. Two minor things: First the bias seems to be pretty high on the output stages maybe between AB1 and class A. That's good for the sound but means the unit runs very warm. Be aware of this and leave lots of room for cooling air to get to the unit. The other thing is the video brightness seems lower running HDMI through the unit. If all video is going through the unit then its just an adjustment on the monitor, but if you are running some video directly to the monitor it may be an issue. Over all two thumbs up!

Crutchfield Customer Review (What's this?)

Looks like I got mine just in time before they went out of stock, and I couldn't be more pleased! This receiver is well worth the money. It is a high-end piece of equipment at a reasonable price. I tried an Onkyo '706, (returned-even with the Farudja chip), then tried Yamaha (returned) and decided to give this Marantz a try. WOW, it's design is perfect, it works like a dream, and the picture quality is awesome. I used the Audyssey EQ auto set-up, wrote down the parameters, tweaked them a bit with manual set-up, and my Klipsch's couldn't sound better. The manual is thick and lengthy, but take time to read it slowly, and it makes sense. One bit of advice to the manual writers-explain what will happen with each setting you can make-not just tell you what settings are available. Above all, my thanks to Crutchfield! They made it possible to even get this Marantz, and everything (including the return process for the other equipment) was A-1.

Inputs and Outputs


Amplifier Section: The Marantz SR6003 A/V Surround Receiver features an 100 watts x 7-channel all discrete amplifier. The amplifier section features seven voltage feedback modules mounted in-line on an extended array of aluminum fins for maximum 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 results.

Front Panel Design: The receiver's front panel features a combination of aluminum extrusion and glass-reinforced resin which shields internal circuitry and absorbs internal and external resonances.

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 SR6003 is equipped with a high-resolution 32-bit floating point Digital Signal Processor (DSP). All elements of the Surround Processor are optimized to the highest standards by the use of selected high performance and discrete components, particularly the A/D and D/A converters and the sophisticated DSP surround decoder.

24-Bit, 192 kHz D/A Converters: The SR6003 uses 24-bit/192-kHz Digital-to-Analog converters for all channels. 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.

Video Up/Down Conversion: The SR6003 can take an analog video input (composite, S-video, component) and up-convert it to HDMI so the video signal can be passed through the receiver's HDMI terminal to your television via a single HDMI cable up to 1080p. The SR6003 can also take any of the receiver's analog video inputs and up-convert or down-convert them to any of the unit's analog video monitor outputs (composite, S-video, component). The receiver's HDMI inputs cannot be down-converted. The HDMI inputs and monitor outputs will support 480p, 720p, 1080i, and 1080p video signals. The component video inputs and outputs will support 480i, 480p, 720p, and 1080i video signals. The S-video and composite video inputs and outputs will support 480i video resolution.

I/P Convert: The video circuit of the receiver is equipped with an I/P conversion feature. When this feature is active, 480i analog video signals input from a playback device can be converted to 480p and progressively output to the component video or HDMI monitor out terminals on the SR6003.

Auto Lipsync Correction: Video signals may take longer to process than audio signals depending on the connected video equipment. When the unit is connected to A TV or Projector which supports Auto Lipsync Correction in HDMI 1.3, audio and video can be automatically synchronized using this function.

Zone System: The SR6003's Zone System mode allows the same audio source or different audio sources to be heard in other rooms other than where the receiver is installed. The Marantz AV receiver features a Main Audio/Video Zone (Main), a second analog Audio Only Zone (Zone A) and a digital Audio Only Zone (Zone B). The Main Zone contains 7.1-channel playback of your audio/video gear in your main entertainment room. The Audio Only Zone A allows analog audio playback of another audio source connected to the receiver in another room of your home via left/right RCA audio output connections to a separate amplifier. The Audio Only Zone B allows digital audio playback of another digital audio source connected to the receiver in another room of your home via an optical digital output connected to a separate amplifier. The SR6003 AV receiver's Surround Back Speaker outputs can be assigned to Zone A so you can power a set of speakers in another room of your home without the use of a separate amplifier. You must turn off the Surround Back channels of the amplifier when using the receiver's multi-room speaker outputs, which will limit you to 5.1 channels in your main room.

Bi-Amp Connection: A bi-amp connection is possible with speakers that have two sets of inputs by combining the Front A and Surround Back speaker connections. This allows you to drive the treble and bass units with separate channels amps, which enable better sound quality. The surround back channels of the amplifier will need to be turned off to bi-amp your front speakers. This configuration will limit your Home Theater to 5.1- channel.

AM/FM Tuner: The Marantz SR6003 features a built-in AM/FM tuner which can automatically or manually store up to 60 AM/FM presets that can be labeled and viewed in a channel list.
