On the AroioDAC, two independent clock chips are used as master clocks, one for the 44.1kHz multiples (e.g., standard CD quality) and one for the 48kHz (e.g., 96kHz or 192kHz Hi-Res files). Thanks to the exact frequency accuracy and high frequency stability, jitter and unwanted modulations are reduced to a minimum. During operation, a small blue LED indicates which master clock is currently active.
To avoid power-related disturbances, the three important areas of the board are fed completely independently of each other with high-precision voltage regulators from Analog Devices.
In order to guarantee the necessary current flow at any time, the circuit board is constructed as a 4-way multilayer (each with its own copper layer for ground potential and the supply lines). In addition, all areas are buffered with generous capacitors.
