Audio-Technica COMBINE 4 IEM Transmitter Combiner

The COMBINE4 IEM transmitter combiner brings together up to four in-ear monitor transmitter signals into a single transmitting antenna. IEM transmitter combination is important for multi-channel systems to minimize intermodulation products arising from multiple adjacent transmitters interfering with one another.

Key Features

• Broadband UHF operation (470-960 MHz range)
• Combines the signals of up to four wireless in-ear monitor transmitters into one antenna
• Centralized power supply with ability to power four individual transmitters
• Four BNC inputs for IEM transmitter signals
• Front-panel LED signal indicators for each input
• Four DC output jacks that supply power to connected IEM transmitters
• Includes one AC cable, four DC cables, and four BNC jumpers
• Full rack width (1 RU)
