DESIGN TECHNOLOGY
The Saturn-R CD/DAC player uses our proven digital to analogue converter and
analogue output amplifier technology coupled with a pair of Wolfson WM8742 digital
to analogue converter IC’s. The Saturn-R has improvements to the CD section
power supply which was a result of the research & development of our reference
Isis CD player along with the improved microcontroller and display drivers.
The Saturn-R uses a high stability master clock and high capacity power supply in
the CD circuitry, high performance PLL digital interface receiver, isolated digital
inputs and high performance power supply architecture in the DAC circuitry.
Signal switching between the CD and DAC functions are performed in the digital to
analogue converter stage. The signal path of the CD section in CD mode is kept to a
minimum.
The DAC USB input has been improved with asynchronous operation at sample rates
of 44.1 to 192 KHz with a bit rate of up to 24bits. The USB input has the same galvanic
isolation as used in the Rega DAC. The USB uses dedicated drivers in the computer
enabling full ASIO operation, thus eliminating signal degradation caused by generic
windows based drivers.
