The COMB4CPB from Audio-Technica is a bundle featuring the COMBINE4 Signal Combiner and the CP Beam Antenna. The COMBINE4 transmitter brings together up to four in-ear monitor transmitter signals into a single front panel mounted antenna connector. Any brand of IEM may be used, as well as any type of directional antenna. It also provides DC power for up to four IEM transmitters to help users reduce cable clutter. The IEM transmitter combination is important for multi-channel systems to help minimize intermodulation products arising from multiple adjacent antenna interference.

The CP Beam antenna is a high-performaning directional UHF antenna in a lightweight, portable package. Unlike other bulky helicals, the CP Beam antenna is quickly deployed and stowed, fitting in a 2RU rack drawer and weighing just 2.5 lbs. 9 dBd of gain makes it an ideal choice for long range applications. Widely used on major concert tours for monitoring and comms, the CP Beam connects to any brand IEM, wireless mic or UHF intercom.
