AIRBOX 20P is made to be used with most MadBoy U-TUBE serial wireless microphone sets. Just check that that frequency will match. An exception is the MadBoy U-TUBE 20PD. The transmitter is not compatible due to a different technical solution. Transmitter works with only two AA batteries, which is less expensive than other 9V battery powered transmitters.
