The ComNet™ FTA/FRA2C1 Series audio multiplexer provides the transmission of two
audio signals and one contact closure over one multimode or single mode optical fiber.
A bidirectional model, FXA2C1(M,S)1, is also available. The modules use 24-bit 96kHz
sample rate digital encoding for superior transmission of balanced line-level audio. Plug­and-play design ensures ease of installation and no electrical or optical adjustments are
required. Bi-color LED indicators confirm operational status. Packaged in the exclusive
ComNet ComFit housing, these units may be either wall or rack mounted.
