AUDIO
PRODUCT SELECTION HINT
The 310B series transmits
standard (monaural) audio
signals. If high-performance
stereo audio should be
required, refer to the 312B
series, page 19, or the 1312B
series, page 26, for digitally
processed audio.
Systems in the 310B series provide reliable voice-grade transmission of audio signals in most applications.
Incorporating AGC circuitry, the system does not require field adjustment. A unique two-color LED at the
transmitter end indicates input audio level and clipping. The basic characteristics of fiber -- no hum or
pick-up, no interference from electromagnetic fields or radio frequencies, and no possibility of ground
loop interference since fiber is not an electrical conductor -- ensure that the quality requirements of
intercoms, paging, and public address systems are met.
