RF Venue COMBINE4 4-Channel Active Transmitter Combiner for IEM Systems

Running multiple in-ear monitor mixes? The COMBINE4 combines signals from up to 4 UHF IEM transmitters in one antenna, minimizing intermodulation distortion.

The COMBINE4 IEM transmitter combiner brings together up to four in-ear monitor transmitter signals into a single transmitting antenna. IEM transmitter combination is important for multi-channel systems to minimize intermodulation products arising from multiple adjacent transmitters interfering with one another.

The COMBINE4 works with any brand IEM and any type of directional antenna operating in the 470-960 MHz range. It is equipped with four BNC transmitter inputs, front-panel LED signal indicators for each input, and four DC output jacks that supply power to connected IEM transmitters. Includes one AC cable, four DC cables, and four BNC jumpers.

Consumer Alert

Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC's wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones

NOTE: None of the wireless systems we carry are capable of violating the FCC guidelines stated above. We are presenting this information as a matter of legally required disclosure.
