Audio connections
The AdderLink XD522 units support analog and digital audio. Line in and
line out connectors are provided on both the transmitter and receiver units.
Additionally, the receiver has dedicated headphone and microphone jacks on its
front panel.
The Line In socket on the transmitter and the Line Out socket on the
receiver are dual purpose. They can accept either 3.5mm analog jacks or mini-
TOSLINK optical fibre connectors. The latter provide access to the optical
S/PDIF (Sony/Philips Digital InterFace) capabilities supported by the AdderLink
XD522 system, which transmits PCM (Pulse Code Modulation) audio at 96KHz.
The digital and analog channels run independently alongside each other via the
CATx link.
Third party adaptors (not supplied) are available to convert between the
mini-TOSLINK connections used on the AdderLink XD522 units and the more
common full size TOSLINK connectors found on many audio/visual devices.
To connect analog audio

on the transmitter to the analog Line Out or speaker socket of the host
computer.

connection of the receiver’s Line Out socket only. There is no crossover
between the analog and digital audio subsystems of the AdderLink XD522
installation.
