, all in high-quality sound thanks to Marantz’s acclaimed advanced digital and analog audio technologies.
Coaxial and optical digital inputs support the decoding of high resolution 192 kHz/24-bit PCM signals which
complement the functions of the high resolution D/A converters that together reproduce a variety of digital
content with superior sound quality. The NA-11S1 is equipped with a USB Type A port (conveniently located on the
front panel) for playing audio tracks from a directly connected iPhone or USB memory device, and a USB Type B
port is provided that supports asynchronous transmission to ensure that signals from a PC are jitter-less. To absorb
unwanted vibrations and preserve audio signal purity, the cabinet structure features a 5mm thick aluminum top
cover, a copper-plated chassis, and aluminum die-cast feet on a dual-layered bottom plate. Considerable attention
to detail has been devoted to the NA-11S1 in the areas of sound quality and construction to give you what you
would expect in a reference-class network audio player.
