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.

The American Fibertek 05B Series transmits single direction
line level audio, 600 ohms balanced or unbalanced,

on one

multimode or singlemode fiber. 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. Equipment may be ordered as stand alone
modules or rack cards that are mounted in the American
Fibertek Card Cage: SR20/2 or SR-20H-2 (redundant power
supplies).
