Multiple

2x4 or 1x8 passive multiple

The Multiple module holds eight jacks. The fourth jack has its make&break connected to the fifth jack. If you plugin a cable to the fourth jack, you separate jack 5, 6, 7 & 8 from 1, 2, 3 & 4. So you can use the module as one 7 x multiple or as two 4 x multiples.
There is a solderbridge on the PCB to ignore the make&break contact of the fourth jack, if soldered the module will be a 1×8 Multiple with no breakups.
