Top HiFi Audio System: SPDIF

The digital connection between the Top HiFi amplifier and the CD changer is an SPDIF connection. SPDIF stands for Sony Philips Digital Interface and is a data transfer standard for digital audio data. The data can be transferred optically via fibre-optic cables or via coaxial cables depending on the unit.

Advantage: the digital data is read by the CD and transferred between the units with the highest possible quality, as no digital/analog conversion is necessary. The Top HiFi amplifier also no longer has to carry out analog/digital conversion. The digital data can therefore be processed directly from the DSP (Digital Sound Processor).
