Overview
With the AC-3, 4-to-1 active transmitter combiner the signals of up to four SR300 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. The AC-3 is suitable for multi-channel monitoring systems for stage use & any application where talk-back signals are to be transmitted.
