Active antenna combiner with DC power distribution for IEM transmitters.

If you operate multiple Sennheiser wireless monitoring systems, your sound mixing station probably looks like a power station. Here's your solution. The Sennheiser AC 3 operates up to four wireless monitoring transmitters from the EW series using one shared antenna. Power is supplied to the SR 300 IEM G3 transmitters over the BNC cables, eliminating separate power supplies for the transmitters.

Includes required NT3-1-US power supply and four 20" BNC cables
