Overview
The Sennheiser AC 41 is an active antenna combiner that lets up to four evolution wireless stereo IEM transmitters share one antenna. It also powers SR IEM G4 transmitters over the BNC cables from the included NT 3-1 supply, so you can leave four power packs out of the rack.
Sharing one antenna also stops rod antennas interfering with each other.
Works with Sennheiser SR IEM G4 transmitters (power and RF) and other ew series stereo transmitters including G3 (RF combining), with the A 1031-U or A 2003-UHF antennas and the GA 3 rack kit.

Forefront Tip
Plan your IEM frequencies with Sennheiser's frequency tools before combining, as intermodulation shows up quickly once four transmitters share one antenna.
