About the Marantz NA-11S1
Elevate Digital Music to Reference Quality
Enjoy the convenience of digital music with crystal-clear sound quality through your home stereo system. Marantz designed their Reference Series NA-11S1 network music player to squeeze every drop of detail and sonic goodness out of digital music files, no matter where they're stored. With Internet connectivity and support for Apple® AirPlay®, you can get music from a wide variety of sources to your speakers for a sound that can be as smooth and lush as any CD. Stream from an iPhone® or iPad® over your wireless home network, or use your Apple device as a remote to stream from a networked computer running iTunes®. Airplay streaming requires a home Wi-Fi® network and a wired connection between your player and home network.
Mac and PC Users Welcome
Not an Apple devotee? That's all right — you can still stream music from a DLNA-compatible networked PC. Or just plug your computer into the rear-panel asynchronous USB input and let the NA-11S1's audiophile digital-to-analog converters give you performance far beyond your computer sound card's capabilities. The player's internal clock takes control of the music data stream, reducing timing errors known as "jitter" that can smear subtle details and make your music sound harsh. Using this USB connection also circumvents electromagnetic and radio frequency noise generated by your PC or Mac for a sonically pure signal that results in a wide soundstage and excellent tonal depth. Fire up some high-res files to really let this player flex its muscles.
Discover New Music
Whether you're interested in discovering new music or checking out old favorites, you'll enjoy the NA-11S1's built-in access to Spotify®, SiriusXM, and Pandora®, as well as thousands of Internet radio stations. It's perfect for endless musical explorations or those times when you feel like being surprised by what song comes up next.
The NA-11S1 offers many options for getting the most out of your digital music. (The NA-11S1 does not include the pictured amplifier, Apple devices or any other components or accessories.)
High-quality D/A Conversion
How does this network player get your digital music to sound so good? The answer lies in the audiophile-grade 192kHz/24-bit DACs, which convert your digital files precisely to clean analog signals for output to your amplifier and speakers, so no details are lost in the process. Plus, Marantz's Hyper Dynamic Amplifier Modules are used in place of standard op-amp chips, for reduced noise and improved dynamic range and detail.
Solid Construction for Stellar Sound
Top-notch audio performance demands a sophisticated design, from the circuit board to the chassis. Marantz optimized this player to minimize interference and distortion for pure music playback. The copper-shielded toroidal power transformer provides a heavy dose of clean current. The copper-plated chassis features a thick aluminum top panel — strong enough to support another component. And the aluminum die-cast feet provide stability as well as protection from external interference — solid footing for uncompromised sound. And it's all backed by Marantz's impressive five-year warranty.
Some wireless streaming systems leave a lot to be desired in the remote department. But Marantz has included a versatile remote control that lets you access network music, tweaks settings, and apply digital sound filters. Plus, you can download the Marantz Control app for your Apple or Android™ device, giving you intuitive touchscreen control on your mobile phone or tablet.
Listen to Computer, Web-based and Portable Digital Media
Equipped with an RJ-45 LAN port, you can connect the NA-11S1 to your home network to access thousands of internet radio stations and music streaming via Pandora, SiriusXM, and Spotify. There’s a front-panel USB type-A port that lets you connect your portable device directly, and it features automatic iPod detection and charging, even during standby mode. The USB type B port on the rear panel lets you connect a PC directly, and our newly developed Ground/Signal isolator technology helps to reduce PC noise for the highest quality sound.
Via AirPlay and your wireless home network, you can stream content from your iTunes library directly to the NA-11S1, and you can also access your iTunes content with the direct PC connection.
Multiple Filters Offer Versatile Listening Options
The latest Marantz DSP processor (DSP PEC777f3) provides precision digital filtering, and the NA-11S1 offers a number of DSP modes that let you tailor the sound to your liking. There are two for digital sources, as well as the option of noise shaping and a DC filter with a 1.7 Hz cutoff.
Exclusive Output Technology Ensures Faithful Playback
For optimum audio fidelity, the NA-11S1 features high current, high-resolution audiophile D/A converters, operating in differential mode for the lowest noise and widest dynamic range. The critical post-D/A current-to-voltage conversion is handled by the latest Marantz HDAM-SA2 devices, which feature precision discrete components in lieu of standard op-amp chips. The final analog output stage features additional HDAM devices, and there are two output choices – unbalanced (RCA) and balanced (XLR). The balanced outputs also feature a phase-inversion option for compatibility with any XLR-equipped pre-amp.
Multiple Ports for Versatile Connectivity
Dual (optical and coaxial) outputs are provided for connection to other components, and there are also dual digital inputs that let you use the NA-11S1 as a DAC with other digital audio sources. There’s also a high-quality dedicated headphone amplifier, which features its own output stage that’s also equipped with HDAM-SA2 devices along with a precision variable analog volume control.
Rugged, Durable Construction
As befits its reference-class status, the NA-11S1 features a rugged chassis with internal copper-plated surfaces. The thick 5mm top panel can easily support the weight of an additional component, and the dual-layer bottom plate and die-cast aluminum cabinet feet provide solid rigidity along with additional resistance from external vibrations. The beefy power supply features a high current toroidal power transformer with multiple oxygen-free coppers (OFC) secondary windings and is housed in a copper-plated enclosure for maximum shielding. Multiple separate circuit boards ensure minimal interference between the various analog and digital stages.
