The American Fibertek 05B-PA receiver operates in conjunction
with the American Fibertek MT-05B Series transmitters. The link
accepts single direction line level audio, 600 ohms balanced or
unbalanced,
transmits the audio over one multimode or
singlemode fiber and provides a 5W @ 70V output to power
remote speaker systems.
The audio is transmitted over the link using FM modulation which
results in an improved signal to noise ratio and a constant audio
output level over the full optical loss budget. Diagnostic indicators
provide a quick visual check of system status.
Designed to be completely transparent, these links require no
field adjustments at installation or additional maintenance
thereafter.
