XGA/Audio Line Transmitter
(see section

), and the
TP-122
XGA/Audio Line Receiver
(see section

).
6.1 Your TP-121 XGA/Audio Line Transmitter
The
TP-121
is an XGA/audio stereo line transmitter that receives an XGA
signal and an unbalanced stereo analog audio signal and transmits them
over CAT 5 cable to a
TP-122
receiver, converting the unbalanced stereo
analog audio signal to digital audio (S/PDIF) stream before transmitting,
thus preserving the quality of the audio signal. In particular, the
TP-121
:
•
Has a transmission range of more than 300ft (more than 100m), and a
20kHz audio bandwidth with an S/N ratio that exceeds 80dB on the
same transmission range
•
Can power or be powered by the receiver over the same CAT 5 cable
•
Is 12V DC fed
