The MIDIMAN Thru 1x4 is a 1 IN/4 OUT MIDI Thru Box designed to send a received MIDI signal to up to four separate devices simultaneously. The device echoes the input signal unchanged across all four MIDI OUT ports, ensuring no signal delay when distributing MIDI output.
No, it draws power directly from the MIDI Out of any instrument or sequencer connected to its MIDI IN.
You should use the standard 9 volt, center pin positive, power jack located on the side of the unit.
