About RF Venue COMBINE4

Be at the forefront of audio and video technology with the COMBINE4 4-Channel Antenna Signal Combiner Bundle. This innovative and high-quality product is expertly designed by RF Venue, a trusted name in the professional audio and video industry.

The COMBINE4 is a user-friendly solution that seamlessly merges up to four in-ear monitor (IEM) transmitter signals into a single output via a rear panel-mounted antenna connector. This versatile device is compatible with any brand of IEM and any type of directional antenna, making it a comprehensive solution for your signal combining needs.

To minimize cable clutter and eliminate the need for multiple power sources, the COMBINE4 also provides DC power to up to four IEM transmitters. This feature is crucial for multi-channel systems, as it helps to reduce intermodulation products that can arise from multiple adjacent transmitters interfering with each other.

Included in this bundle is the CP Beam Antenna, a high-performance, directional UHF antenna that is both lightweight and portable. Unlike other bulky helicals, the CP Beam is easily deployed and stowed, fitting comfortably in a 3RU rack drawer and weighing a mere 2.5 lbs. With 9 dBd of gain, it's an ideal choice for long-range applications and is widely used on major concert tours for monitoring and comms.

The bundle also includes a 25' RG8X Coaxial Cable, a crucial component for flawless RF performance. This premium, low-loss, 50 Ohm RG8X coaxial cable is made in the USA and comes with BNC male connectors for wireless audio applications. The cable is double shielded with a braid over foil, offering the perfect balance between loss and flexibility.

Whether you're setting up for live events such as concerts, theater productions, or sporting events, the COMBINE4 4-Channel Antenna Signal Combiner with CP Beam Antenna and 25' RG8X Coaxial Cable Bundle is a durable and compact solution for your signal combining needs.
