The Sennheiser AM 2 is used with the GA2 Evolution Series rackmount kit to relocate the two antennas from the back of a rackmounted receiver to the front of the rack. It is compatible with EW G2/G3/G4 and EW-D receivers as well as SR 300 IEM transmitters.
The AM 2 comes with two 50-ohm BNC cables and mounting hardware.
