BlackMax GPS Synchronizer Module

The GPS1 GPS Synchronizer Module from MH Corbin employs a highly accurate GPS signal to provide a very precise transmitter frequency. This allows multiple HAR stations, with overlapping broadcast signals to synchronously broadcast the same audio message with superior sound quality. 

The combined coverage area is limited only by the number of HARs in the network, and listeners moving through the network will hear the same message as if it were being generated from a single transmitter. 

Quick Facts

  • Allows extension of broadcast coverage over large areas with multiple HAR systems
  • GPS antenna and cable included
  • Suitable for permanent or portable systems



  • Front panel adjustment for fine tuning the RF phase angle
