Maximise the potential of your digital audio.
Rega DAC is a 16/20/24-bit at 32kHz to 192kHz digital to analogue
converter incorporating an enhanced version of the Rega designed
circuit. Developed to be simple to set up and use, the Rega DAC is
designed to optimise performance from any two channel PCM digital audio
source such as a CD player PC or streaming device.
With the PC/Laptop and MAC now widely accepted as creditable mediums
for storing and streaming music. The use of high quality lossless files
such as WAV, FLAC and ALAC offer performance through the DAC equal to
and in some cases better than red book CD.

two Toslink SPDIF inputs and an isolated USB input. The Rega DAC is
designed and engineered to perform way above its class.
input stage comprises a Wolfson digital receiver with a high stability
low jitter clock. The receiver and PLL have their own dedicated power
supplies. The DAC stage comprises of a pair of parallel-connected
Wolfson WM8742 DAC's, which are driven via a buffer stage, which
ensures the integrity of the data being fed to the DAC IC's similar to
the arrangement used in the Isis (Rega's refrerence CD player). Great
care has been taken to remove noise generated by the PC and other input
sources. During development this was identified as a major drawback
with many DAC's on the market today.
output amplifier employs a discrete differential multiple feedback
filter and output amplifier, with a high cut-off frequency for use with
higher sample rates. We decided not to use a sample rate converter and
process the data at the incoming sample rate which keeps the signal
processing to a minimum. Jitter was minimised by synchronously clocking
the digital data with our receiver PLL (removing any jitter from the
All the capacitors associated with the analogue signal path are
Nichicon FG bypassed with MMK polyester capacitors, and low impedance
conductive polymer capacitors are used for DAC decoupling. The power
supply utilizes a toroidal transformer, fast rectifier diodes and again

microcontroller, separate from the digital & analogue audio
stages. Special attention being paid to the inter IC control signals
ensuring the control data noise is kept to a minimum.
