The Lehle MIDI Junction networks up to four Lehle Lehle SGoS (= Second Generation of Switching) Switchers via standard stereo jack-plug adapters, using MIDI program-change commands for communication between the individual Switchers. External MIDI equipment that responds to MIDI program-change commands can also be connected by means of a five-pole DIN socket.
Combination of multiple MIDI Junction units permits networking of up to ten Lehle SGoS Switchers.
The Lehle MIDI Junction in its virtually indestructible housing of 1.5 mm thick steel sheet is an entirely passive accessory, with no need for a power supply.
