Connecting 2 ams to H2 Series printers-are buffers necessary?

amongst my bambu lab collection, I have an X1C, an H2D and an H2S.

Currently I have 4 ams 1 connected to the X1 via a 4 way AMS buffer. The H2S and the H2D each are connected to an AMS 2 pro.

I wish to reconfigure everything.

I wish to use two AMS 1 with my X1 Carbon, 2 AMS1 with the H2S and 2 AMS 2 Pro with the other H2D.

my difficulty to understand is that the X1 needed the AMS Hub to handle more than one AMS.

From what I have looked up and seen, connecting two AMS units to the H2S or H2D need simply a splitter. my two questions are…

(1) Is the AMS hub required to connect two AMS 2 PRO units to the H2D?

(2) Is the AMS hub required to connect two AMS 1 older units to the H2S?

I have four single buffers which I do not use any more which came with each AMS1 unused.

I want to know how best to go about it.

I will put it in another way.

Two AMS 1 connected to an H2S and Two AMS 2 Pro connected to an H2D.

any buffers needed or just two way splitterS?

Thanks for any input.

Yes it’s the best, more filaments more coloured printing

Not sure if this is semantics, or maybe I misunderstand… but the filament buffers are built into the H2 series already. One for each nozzle (so two on C and D models). There’s no reason or way to add more, nor are any hubs needed.

To connect multiple AMS units to one buffered input, only a “splitter” is required, or technically a “N-in, 1-out” adapter like Bambu 4-in-1 PTFE Adapter | Bambu Lab US Store. Each AMS (or external spool/feeder box) goes to an input on the adapter, and the one output from adapter goes to one buffered input on the H2. To use multiple inputs for each of the C/D nozzles, 2 adapters would be required, one for each buffer input.
