A turnkey 4-channel IEM upgrade pack designed to provide reliable, high-performance wireless transmission for in-ear monitor systems. The package combines the compact, weather-resistant CP Stage circularly polarized antenna with the COMBINE4 active IEM transmitter combiner and a 25' low-loss RG8X coaxial cable.

The CP Stage features a rugged IP-rated enclosure and circularly polarized design that provides consistent signal coverage for IEM bodypacks regardless of performer orientation. Its compact, stand-mount design makes it well suited for touring, band flypacks, and permanent outdoor installations.

The COMBINE4 combines up to four IEM transmitter signals into a single antenna output, reducing the need for multiple antennas and helping lower intermodulation distortion for improved system performance and reliability. It also includes DC power interconnects for compatible IEM transmitters and coaxial interconnects for a complete setup.
