Overview: The Arcam rDac-KW is an external audiophile-grade DAC with state-of-the-art
digital-to-analog conversion technology. The rDac-KW offers supreme audio quality
for the most demanding music lover. Housed in a slender, precision-cast case the
rDac-KW offers an ideal upgrade for conventional sources and network audio products
alike. Offering coaxial, optical, and USB digital inputs - the rDac-KW renders
music with stunning accuracy. The rDac-KW also includes an antenna for wireless
music streaming from your iPod/iPhone or computer (required wireless
transmitters sold separately).
24-Bit DAC: The Arcam rDac-KW is equipped with a Wolfson 8741 24-bit
multilevel Delta-Sigma DAC (digital-to-analog converter). The rDac-KW will get the
best audio sound out of your sources, such as your Blu-ray player, DVD player,
CD player, and your Computer - which don't have an internal DAC of this
reference quality, provided by the Wolfson Microelectronics world class 8741.

Asynchronous USB Technology: The Arcam rDac-KW is equipped with dCS (Data
Conversion Systems) Asynchronous USB Technology. This unique system is usually
reserved for ultra high-end HiFi and professional audio applications.
Asynchronous USB technology allows a precision clock to drastically reduce the
level of jitter from USB music sources and delivers a massive improvement in
sound quality over the standard USB 'adaptive' system. The result is
audiophile-grade sound, regardless of the digital audio signal.
Digital Inputs: The Arcam rDac-KW is equipped with a coaxial and optical
digital input on its rear-panel. CD players, DVD players, Blu-ray players, and
Game systems can be connected via coaxial or optical leads to receive a dramatic
increase in sound.
