The A-181 is a simple multi-connector. It has two separate sections, the upper is a straight connection between one quarter inch socket and two 3.5mm sockets.
The lower is a straight connections between a stereo quarter inch socket separated to two 3.5mm sockets (one to tip and one to ring of the stereo jack socket).
Note that the A-181 is purely passive and therefore does not need power, thus it’s power consumption is zero (0mA).
