The midiBeam system consists of two boxes, TX02 and RX02.

Attached to the instrument is the TX02 transmitter, powered by two AAA batteries. It is a small plastic box, with an LED and one pushbutton on the top for "PAIRING". The MIDI plug is hanging on one end of a short cable. The TX02 can be attached to the instrument by Velcro tape.

The RX02 receiver is powered through the mini USB socket either from a computer or from a USB power supply. It has an LED and a "PAIRING" pushbutton as well. The MIDI output is provided either through USB or the DIN MIDI Output socket. There is a DIN MIDI Input socket as well; if the device has no radio connection then it functions as a standard MIDI Interface to a computer. No special driver installation is necessary.

Radio connection is established between a pair of devices automatically on one of 76 radio channels by using the pairing buttons on both units. This means that up to 76 systems can coexist at one location.

The radio transmission is using the 2.4 GHz band that is free for public use all over the world. Radio power is programmable in four increments.

The transmitter can power off automatically, if it is not used for a certain time. Programmable options are 10, 30, 60 minutes or no power off.
