audio transmitters provide remote inputs for SonaFlex audio systems via Cat 5e/6 cable. You can configure the Override button on the FlexPort module to play the connected source on one or more outputs. Each FlexPort Transmitter adds up to four additional audio inputs (2 per FlexPort input) to each SF-16M
. FlexPort modules can be located up to 500 feet from the SF-16M, and can be installed as a wallplate or on any flat surface.
