Audio Technica COMBINE4 IEM transmitter combines up to four in- ear monitor transmitter signals into a single front panel mounted antenna connector, provides DC power for up to four IEM transmitters

The COMBINE4 4-Channel Antenna Combiner with CP Beam Antenna and Cable Bundle from RFvenue is an antenna combiner that was developed for cross-brand flexibility for IEM (In-Ear Monitor) systems. The four-channel Radio Frequency (RF) combiner receives four incoming IEM transmitter RF signals and combines them to a single convenient front-panel mounted output connection. The combiner features a high-quality internal power supply and includes DC and RF jumper cables required for four-channel IEM system operation.

The CP Beam Antenna provides high gain for wireless microphones and IEMs in a lightweight, portable package. Unlike other bulky helical antennas which require heavy flight cases, the CP Beam is quickly deployed and stowed, fitting in a 2RU rack drawer and weighing just 2.5 pounds while delivering 9 dBd of gain.
