Abacus AroioDAC

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.
