The RDL FP-TPX3A Format-A Twisted Pair Remote Controlled Mixer is a 3-channel audio mixer used for controlling multiple sound sources within zones in commercial PA and paging audio systems. The FP-TPX3A features 3 inputs that may be used as balanced or unbalanced, microphone or line level connections, and phantom power is sent to microphones and sources that require it. Connections are made over Format-A twisted pair inputs, and a pair of unbalanced RCA outputs are also featured. The Audio Detect Outputs feature an LED that detects output signal, as well as trigger outputs that automatically start/shut down compatible audio gear, in order to maximize energy efficiency and preserve the life span of the connected audio sources.
