The COMBINE4 active IEM transmitter combiner brings together up to four in-ear monitor transmitter signals into a single, more powerful transmit antenna, eliminating the use of problematic multiple antennas while lowering the buildup of unwanted Intermodulation.
It provides DC power for up to four IEM transmitters to reduce cable clutter and wall warts. Combining transmitters is critical to multi-channel systems, in order to minimize intermodulation artifacts arising from multiple adjacent transmitters interfering with one another. Suitable for use with any brand of transmitter (up to 100mW) and passive antenna. The CP Beam Helical antenna is a recommended accessory for the COMBINE4 and is available in a bundled package.
Freedom to place one directional antenna outside the rack for better line-of-sight and improved wireless performance.
1RU Full rack width to install near transmitters. Includes cabling accessories to connect and power up to four wireless transmitters.
Compatible with all manufacturers.
The COMBINE4 Transmitter Combiner
The COMBINE4 is also sold bundled with CP Beam Antenna (CPB). This turnkey bundle includes everything needed to configure up to 4 channels of In-Ear Monitors. Including Premium made in USA low loss double shielded coaxial cabling coax cable.
This clever setup effectively creates a cost effective eight channel combiner for much, much less than a standalone active 8 channel transmitter combiner. Route both outputs of two four channel IEM transmitter combiners through a single passive 2X1SPLIT, and finally into a helical antenna.

RF combiners are used in the A/V world for pushing multiple IEM transmitter signals through a single antenna.
RF combiners are used in the A/V world for pushing multiple IEM transmitter signals through a single antenna. They solve the same problems as distributors, except the signal path is reversed--instead of passively receiving multiple signals through one antenna pair, they actively send multiple signals through a single antenna.
For live sound applications where each member of a band has a custom mix routed through an individual IEM (in-ear monitor), combiners are essential components. They reduce clutter at the rack by eliminating whip antennas, provide DC power, and reduce intermodulation caused by antenna farming while allowing the technician to directly focus a beam of RF directly at the stage--assuring all talent receives their IEM mix interference free.
Multiple transmitters: one antenna.
Yes, as a general rule
Yes, as a general rule: Wireless mic systems, distro systems, antennas, and coax cables from nearly any brand can be successfully used together, provided that they operate in the same frequency range and within the rated power levels. You can add an RF Venue distro to an existing distro from another manufacturer to provide for additional wireless mic systems. It is unlikely, however, that you could mix a transmitter from one manufacturer with a receiver from another even if the frequencies match because of their coding schemes.
Our venue usually runs 4-5 IEM systems and 10 wireless microphones per set. Finding enough RF space in our coordination was next to impossible without intermods. The install was super easy, and we've had zero dropouts or noticeable Intermodulation distortion since the install. Two thumbs way up!” - Jon on Amazon" >
I purchased an RF Venue Combine4 along with a Distro4 and Diversity Fin Antenna (all by RF Venue) from Sweetwater recently. After installation and great tech support from Sweetwater and RF Venue, my rack was ready. I just used it to run multiple wireless mics and 9 wireless IEM packs in a heavy RF environment. My system was run on the same stage with a production company running 8 wireless microphones and 8 wireless IEM packs....and another stage” -
