With the AC 3 4-to-1 active transmitter combiner, the signals of up to four SR 300 IEM G3 type transmitters can be combined onto a single antenna.

The integral active RF amplifiers ensure that the input signals are combined onto the common antenna output with no distribution attenuation.

The AC 3 incorporates DC distribution to enable simultaneous powering of up to four transmitters via its BNC sockets. 

A single NT 3-1 table top power supply is required to power the AC 3 and the connected transmitters. 

Using the GA 3 rack adapter, one AC 3 and one stationary SR 300 IEM G3 type transmitter can be mounted into a 19” rack.
