Shouldn't that be 3 (three) x 1:4 Buffered Multiples with bi-color leds?

Nope. The Palette "bar" is more than that. It has your external DC input, power switch, the three buffered mults, two adders, four 1/4" I/O jacks, and MIDI I/O for 3.5mm TRS or USB. Pretty smart design, as those modules are useful but they tend to rob space in 3U rows. This way, they literally use NO module hp at all.
