The A-180.1 is a simple multi-connector. It has 2 sets of 4 inter connected sockets, so that you can patch more inputs or outputs into any module. The sockets can be joined together for one set of eight.
The A-180.1 is supplied as two sets of four, but can be linked by an internal solder bridge so that all eight sockets are connected together.
Note that the A-180.1 is purely passive and therefore does not need power, thus it’s power consumption is zero (0mA).
