CES Ed-Lab 700 Computer Systems Lab

Notice all the multiple jacks! I was surprised to see any multiples on a banana jack system. I think a lot of the stock banana cables supplied with these systems were sort of economic and don't stack. There could be some potential educational clarity to using a multiple, but it seems sort of against the philosophy of banana patching.

Multiples on banana patchbays redundant? I think not. Suppose you stacked two wires and you want to repatch the lower one (let's call that A). You'ld have to remove the upper, move the lower, repatch te upper.
With multiples you just repatch wire A. Much faster.

Was thinking about your comment. You still have to take the time to patch to and from the multiple. But I agree it might come in handy if you know you'll be swapping a lot of specific connectors and I would guess if you had stacking bananas, students might stack a large number and break the one on the bottom.
