The rDAC is available in two versions, the straight rDAC for use with local, directly connected sources and the rDAC-kw which adds wireless functionality using KLEER technology. Both rDAC variants offer supreme audio quality for the most demanding music lover. Housed in a slender, precision-cast case the rDac offers an ideal upgrade for conventional sources and network audio products alike. Soon after the birth of the CD player Arcam was the first company to add outboard digital to analogue (DAC) conversion as a sonic upgrade. The result was a dramatic increase in sound quality and its" "Black Box" DAC went on to define a whole new product category. In recent years computer and streaming audio has added to the popularity of the outboard DAC. In response Arcam have underlined their position at the forefront of this technology with the new rDAC. Simple to look at, the rDAC"s sleek cast aluminum casework hides the very latest digital conversion using, at its core, the outstanding 8741 IC from Wolfson Microelectronics. Offering coaxial, optical or USB digital inputs the rDAC renders music with stunning accuracy and delivers a performance of thrilling musicality. Uses for the rDAC are almost endless. Internet radio, set-top boxes and game stations can be connected via coaxial or optical leads to receive a dramatic increase in sound quality. PCs and Mac computers running music programs such as iTunes® or Windows Media Player can feed the rDAC via its USB input where special re-clocking circuitry has been deployed almost eliminating the jitter (timing inaccuracies) and noise usually associated with music in the computer environment. To achieve this Arcam have teamed up with dCS (Data Conversion Systems), licensing their Asynchronous USB Technology*. This unique system is usually reserved for ultra high-end HiFi and professional audio applications
