Abstract: COMPUTER AUDIO JOYSTICK AND MIDI BREAKOUT BOX OF THE DICLOSURE A MIDI/joystick breakout box is described which incorporates a shielded connector, a shielded cable, and a terminal block including a circuit board with an extensive ground plane surrounding the joystick connections and shielding the MIDI circuitry on at least three sides. The terminal block is a housing which acts as a radiation shield. The housing or terminal block may be made of an injected molded plastic material containing electrically conductive strands of metal or the housing may be plated or painted on its interior surfaces with an electrically conductive material to form a shielding layer which may then be further connected to the ground plane of the electronic circuit board contained within the terminal block housing. The terminal block provides connectors for MIDI-In, MIDI-Out MIDI-Thru and a pair of joystick interface connectors which allows the capability to connect both MIDI devices and two joysticks to the audio adapter card simultaneously.
