The 6505 is a digital audio distribution amplifier that takes one S/PDIF digital audio input and distributes the identical signal to five S/PDIF outputs. It supports sampling rates from 32kHz to 192kHz and re-clocks and re-samples the input signal to enable transmission over longer distances. It has compact dimensions allowing three units to fit side-by-side in a standard 1U rack space when used with an optional rack adapter.
