DESCRIPTION
The IFS AT/AR7400 series audio multiplexer provides for the simultaneous transmission of four audio signals over one multimode or single mode optical fiber. The modules use 20-bit digital encoding for
superior transmission of balanced line-level audio. Plug-and-play
design ensures ease of installation and requires no electrical or optical
adjustments. The modules incorporates LED status indicators for
monitoring critical operating parameters such as power, audio level
input and optical lock. The modules are available in either stand-alone
or rack mount versions.
