RF Venue COMB4CPB | 4-Channel IEM Combiner with CP...
$1,799.00
The RF Venue COMB4CPB is a four-channel wireless IEM upgrade package that combines up to four in-ear monitor transmitter signals into a single CP Beam antenna system. It brings together the COMBINE4 active transmitter combiner, circularly polarized CP Beam antenna, low-loss RG8X coaxial cable, RF jumpers, and DC power cables to create a cleaner and more reliable multi-channel IEM setup.
The RF Venue COMB4CPB is designed for live sound professionals, performers, venues, houses of worship, and touring systems that use multiple wireless in-ear monitor transmitters. Instead of operating several closely spaced transmitter antennas, the COMBINE4 actively combines as many as four RF signals into a single antenna output.
The included CP Beam is a lightweight folding helical antenna with right-hand circular polarization and 9 dBd gain. Its directional beam pattern helps focus RF energy toward the performance area, while circular polarization helps maintain a more consistent signal as bodypack antennas move through different orientations. The antenna operates from 470–698 MHz and collapses for easier transport and storage.
The COMBINE4 is a full-width rackmount transmitter combiner with four BNC RF inputs, a single antenna output, and four DC power outputs. Its internal universal AC power supply allows the unit to provide 12V DC power to compatible transmitters, helping simplify rack wiring. Each RF input supports a maximum input level of +20 dBm, or 100 mW.
With the CP Beam antenna, COMBINE4, antenna mounting hardware, RF and DC jumpers, and a 25 ft RG8X BNC cable included, the package provides the core components needed to upgrade a four-channel IEM system for cleaner rack installation and more controlled RF coverage.
