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. Arcam and dCS have had a long and fruitful
relationship that goes back to the highly innovative Alpha 9 & CD23
versions of dCS’s Ring DAC
The dCS 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 design of precision clock circuits and general digital and analogue
audio engineering are some of Arcam’s key strengths. The results from
the highly affordable rDac are stunning regardless of the digital audio
The wireless version of the rDAC, the rDAC-kw comes ready to be connected to the rWave wireless USB dongle or rWand
iPad/iPod dongle. These helpful accessories enable music to be sent
wirelessly to your audio system from a laptop or mobile music device via
the rDAC. The internal wireless receiver also features dCS technology
and offers music lovers with large stored collections a level of
performance that was previously only available from expensive audiophile
rWave or rWand dongle $50 with purchase of unit, normally $100.
