This Receiver Has It All
The Marantz SR6004 110-watt home theater receiver delivers an astonishing array of features while adhering to the company's signature tradition of superior sound quality. It features Bluetooth and four-in / two-out HDMI connectivity, an array of Audyssey technologies, 110 watts per channel, and the décor-pleasing cosmetics Marantz is justly famous for.
The SR6004 gives you access to all of your favorite sources. Want the best image and sound from your favorite Blu-ray discs or a set-top box? Let the SR6004’s extensive HDMI array open your eyes and ears. With four inputs and two outputs (all 1.3 capable, by the way), you’ll enjoy audio formats like Dolby TrueHD and DTS HD Master Audio, while seeing visual images as they were meant to be seen.
Satellite Radio Options
The SR6004 also gives you the option of Sirius or XM satellite radio in addition to FM and AM. Just add the appropriate antenna and subscription, and you're ready to go.
iPod Capability
Want to use your iPod’s playlist for long-term enjoyment? Just connect it to the front panel USB input. Then you’ll hear and see all the files you’ve carefully collected. You’ll also enjoy the fact that the USB input is perfectly happy with MP3, WMA, and WAV files from other portable devices, too.
You’ll find an RX101 Bluetooth adaptor included with your SR6004 so you can wirelessly enjoy files from any Bluetooth-enabled source. Wait until you hear your iPhone and iTouch collections through your home theater system! And the RX101 is an IR (infrared) sensor, too, so you can place all your components in a remote location and still maintain complete control.
Superb Sound Quality
If you’re concerned about compromised sound quality with compressed files, let the M-DAX (Marantz Dynamic Audio eXpander) circuit fill in the missing high frequency content for true-to-life fidelity.
Thanks in part to an advanced digital audio signal processor from Texas Instruments, the SR6004 brings you Dolby Pro Logic IIz with exciting height information, so that planes flying overhead actually sound as though they’re overhead!
Automatic Speaker Calibration
You’ll also find a full array of Audyssey technologies to help you recreate the perfect entertainment environment. Audyssey’s Dynamic Volume compensates for level differences as you switch from source to source. It even takes the “annoyingly loud” out of commercials so they don’t overwhelm your ears. Dynamic EQ maintains the original bass-to-treble tonal balance regardless of how loudly or softly you play your favorite music or movies. Finally, MultiEQ automatically evens the frequency response of your room and speakers to let you enjoy a whole new level of clarity.
Multi-zone Operation
Enjoying all this through your main system is certainly fine but having the convenience of multi-zone operation is even better. Here, the SR6004 gives you the option of second zone/second source output so you can enjoy a soundtrack in one room and a MP3 in another. And you can select either mono or stereo for second zone listening.
Upscaling to 1080p
Video capabilities may be even more exciting. Thanks to a multi-purpose video processor from i-Chips Technology, the SR6004 easily converts composite or component video signals to digital while upscaling them to full 1080p definition for output via HDMI. There’s also a component video output for a second zone and automatic Lip Sync so picture and sound arrive simultaneously at your favorite viewing/listening location.
Custom Install Features
A detachable AC cord, RS232C and IR flasher inputs, DC trigger outputs, an easily-placed chassis that’s less than 16” deep, and Front Key Lock which inactivates all the front panel controls make the SR6004 a perfect candidate for custom installation. The new hand-held remote controller features an LCD display, backlighting, and learning capability so you can use this remote for multi-brand systems. And it’s been preprogrammed with BD (Blu-ray Disc) command codes for players by most major manufacturers.
Don’t forget the color GUI that lets you easily set up your receiver so you can enjoy all its capabilities.
Seven Channel In-line Design
The seven channel in-line design uses voltage feedback for reduced distortion. A space-efficient and well regulated EI-core transformer pairs with an array of custom 20,000 microfarad capacitors to provide instantaneous current delivery when a demanding source calls for it. Even the power supply devoted to HDMI and DSP circuits is a linear design that avoids the noise common to “switching” supplies. HDMI circuits benefit from a phase lock loop (PLL) in the power supply for reduced jitter and even better sound quality. In addition, the analog audio circuitry sits on its own circuit board for maximum isolation. |
