The COMBINE4 IEM transmitter combiner gathers up to four in-ear transmitter signals to a single antenna connection on the front panel. All IEM brands can be used, as well as all types of directional antennas.
It also provides DC power to up to four IEM transmitters to reduce cable interference. IEM transmitter combination is important for multi-channel systems to minimize intermodulation / interference that can occur from multiple adjacent transmitters. The CP Beam antenna is recommended as an accessory for COMBINE4.
