NEW REGA RESEARCH DAC -
Maximise the potential of your digital audio.
The 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.
Housed in a custom aluminum and steel case and boasting a pair of Wolfson DAC IC's, 5 user selectable digital filters, two isolated Co-axial inputs, two Toslink SPDIF inputs and an isolated USB input. The Rega DAC is designed and engineered to perform way above its class.
The 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 reference 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.
The 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 input signal).
