The Phono Input Port
The Serial Data Input module is the input point for digital audio signals
coming from MCA768/MCK768. It is the third component in this troika which makes it possible to
phono signals at the highest standard. The component serves as a receiver
of the digital phono signal.
In this module in addition the required RIAA equalization and also other characteristics necessary when playing Venyl-records are calculated in four digital signal processors in real time. This is performed at the very high sampling frequency of 768kHz.
Digital Arithmetic-logic Unit
You may wonder why this effort is done. The answer is very simple. The faults caused in a 48 bits wide digital arithmetic-logic unit are much smaller than ever possible in any analogue equalizer. The results are arbitrarily often reproducible at any time.
