RF Venue COMB4CPB 4 Channel In-Ear Monitor Upgrade Pack

The RF Venue COMB4CPB is a 4 channel in-ear monitor upgrade pack including a CP Beam Antenna, Combine4 Transmitter Combiner and Coax Cable.

• CP Beam Antenna: The CP Beam™ Antenna is a lightweight, circularly polarized beam antenna designed to deliver a reliable signal for in-ear monitors (IEMs), wireless microphone systems, and other UHF communication devices. Unlike other antennas that suffer from signal dropouts, the CP Beam ensures consistent performance. This antenna is easy to set up and transport, fitting neatly into a 3RU rack drawer and weighing only 2.5 lbs. It compresses for convenient storage, making it a more practical option compared to bulky helical antennas that need flight cases. The CP Beam is quick to deploy and stow, adding to its user-friendly design.

• Combine4: The COMBINE4 active IEM transmitter combiner merges up to four in-ear monitor transmitter signals into a single, more powerful transmit antenna. This eliminates the issues associated with using multiple antennas and reduces unwanted intermodulation. It also provides DC power for up to four IEM transmitters, helping to reduce cable clutter and the need for multiple power supplies. Combining transmitters is essential in multi-channel systems to minimize intermodulation artifacts caused by adjacent transmitters interfering with each other. The COMBINE4 is compatible with any brand of transmitter (up to 100mW) and passive antenna.

• Coaxial Cable: Coaxial cables can be the difference between flawless RF performance and system failure. Even minor damage to coaxial cable can cause significant signal loss or short out. RF Venue offers premium, USA-made, low-loss, 50Ω RG8X coaxial cable with BNC male connectors for wireless audio applications. Our cables are custom-made to our specifications, featuring a double-shielded braid over foil that balances loss and flexibility. Each cable is terminated in-house and quality checked on calibrated Agilent network analyzers to guarantee performance. RF Venue stocks a range of lengths from 5’ to 150’.
