Clear-Com PTX3 19

The PTX3-19 is a UHF wireless IFB transmitter base station on frequency block 19 (486.4-511.9 MHz), feeding interruptible foldback to talent wearing the IFBR1B-A1 receiver. It sends program audio plus the director's cues to on-air talent so they hear the show and get told when to move.

The transmitter tunes across its block in 100 kHz steps and puts out 250mW nominal of FM RF, with menu-selectable low-frequency roll-off and multiple audio modes. It runs from the supplied 12V power supply or any 6-18V DC source and ships with a right-angle quarter-wave BNC monopole antenna.
