Don't let your racks get pushed to the back.
The Sennheiser GA 3 Rack-Mount Adapter mounts 2 G3 EM receivers or two Sennheiser SR transmitters side-by-side in one rack space. Use the GA 3 to rack a single Sennheiser EM/SR. When using the single option, use the 2 holes for the AM2 antenna front mount relocation kit, located in the included front panel. Mount the antennas up front where reception is vastly improved over being stuck in the back of your rack.
