RF Venue COMB8CPB – 8-Channel IEM Pack with CP Beam Antenna

Product Overview

The RF Venue COMB8CPB is a complete 8-channel in-ear monitor upgrade bundle pairing the COMBINE8 IEM transmitter combiner with the CP Beam circularly polarized antenna and all required cabling. The CP Beam focuses signal directly on performers with a 70-degree beam pattern and 9 dBd gain, while the COMBINE8 consolidates up to eight IEM transmitter signals of any brand (50 mW or less) into a single antenna output. This bundle eliminates the “antenna farm” problem common in multi-IEM deployments and provides DC power to all 8 transmitters, removing the need for individual wall warts.

Product Description

In-ear monitor systems with multiple transmitters require either a cluttered array of individual transmit antennas, or a combiner system that consolidates those signals into a single high-performance antenna. The COMB8CPB does the latter: the COMBINE8 accepts signals from up to eight IEM transmitters via BNC inputs and combines them into a single RF output, which feeds the CP Beam antenna for transmission to performers on stage.

The CP Beam is a circularly polarized helical antenna specifically engineered for IEM transmitter applications. Its circular polarization maintains consistent signal strength as performers rotate — unlike linearly polarized antennas, which experience signal drops when the transmitter antenna and receive element are cross-polarized. The 70-degree beam pattern focuses RF energy toward the stage, with a typical range of up to 600 feet and 9 dBd of gain, effectively increasing the system’s transmit power by nearly eight times over a comparable system using the lowest transmitter output setting.

The CP Beam folds flat for transport, fitting in a 3 RU rack drawer, making it a practical choice for both permanent installation and touring applications. The COMBINE8 also includes an LED indicator that activates when any input signal exceeds +5 dBm, aiding setup and troubleshooting. The included DC Octopus 8-connector cable allows the COMBINE8 to distribute 12 VDC power to up to 8 compatible IEM transmitters directly, eliminating wall warts in the rack.

The COMBINE8 frequency range for the USA and Canada is 470–608 MHz. The CP Beam operates from 470–698 MHz for international compatibility. Both units are compatible with all major IEM transmitter brands including Shure, Sennheiser, Lectrosonics, and others.

Key Features

• 8-Channel IEM Combiner (COMBINE8) — Combines up to 8 IEM transmitter signals into a single antenna output with 65% improvement in harmonic distortion over comparable 4-channel systems.
• CP Beam Antenna — Circularly polarized, 9 dBd gain, 70° beam, up to 600 ft typical range. Folds flat for 3 RU rack storage.
• Circular Polarization — Consistent IEM signal regardless of performer orientation; eliminates polarization dropout common with linear antennas.
• DC Octopus Power Distribution — Included 8-connector cable powers up to 8 IEM transmitters from the COMBINE8, removing wall warts.
• LED Overload Indicator — Activates when input signal exceeds +5 dBm for straightforward setup verification.
• Brand-Agnostic — Works with any IEM transmitter operating at 50 mW or less in the UHF TV band, regardless of manufacturer.
• Complete Bundle — Includes 25' RG8X antenna cable, 8 BNC jumper cables (1.5 ft), DC Octopus cable, and AC power cable.

Technical Specifications

Frequently Asked Questions

Does the COMB8CPB work with any brand of IEM transmitter?

Yes. The COMBINE8 accepts signals from any IEM transmitter operating at 50 mW or less in the UHF TV band (470–608 MHz USA/CAN) with a BNC antenna output, regardless of manufacturer.

Why is circular polarization important for IEM systems?

IEM receiver packs worn by performers rotate as the performer moves, causing polarization mismatch with linearly polarized transmit antennas. Circular polarization maintains consistent signal transfer regardless of receiver pack orientation, reducing audio dropouts during performance.

Can the CP Beam be used for permanent installation?

Yes. The CP Beam includes standard microphone stand mounting threads (1/4-20, 3/8-16, 5/8-27) and can be permanently mounted on a stand or custom bracket. It folds flat for storage and transport in a 3 RU rack drawer.

What does the DC Octopus cable do?

The DC Octopus cable connects to the COMBINE8’s 12 VDC output and provides individual DC power connectors for up to 8 compatible IEM transmitters. This eliminates individual wall warts, reduces rack cable clutter, and allows the COMBINE8 to serve as a single power source for the entire IEM transmitter rack.

Is the COMB8CPB suitable for outdoor or touring use?

Yes. The CP Beam is rated for operating temperatures from -23°C to 54°C and folds flat for transport. For outdoor permanent installation, the CP Stage antenna variant (COMB8CP-STAGE) provides an IP-rated weather-resistant enclosure.
