Question in subject says it all. But the real question following that is: How do we connect the AMS in a 2x and above AMS configuration
PTFE adapter
PTFE tube can connect 4 feed tubes to the printer at the same time. When connecting multiple AMS 2 Pro to H2 series printers, the PTFE adapter is required.

Thats an additional accessory, isnt it?
tbh - I have no idea how that should work - but I am also new in Bambu Lab Printers.
Here the accessory link for approx 5 EUR
I found it on Aliexpress too
As for me the AMS HT was sold out already I currently have ordered 2 AMS 2 Pros (1 from the combo on additional) - I can start use my setup - and when the AMS HT is available again - there might be light in the dark 
I think when you have only 2 AMS, you can connect each AMS to each to each nozzle with no need for a hub, or 4 to 1 adapter. However, if you want to connect multiple AMS to one nozzle, then a hub or 4 to 1 adapter is needed.

I am still thinking, if i should get a second AMS 2 pro for the second nozzle, or if i should wait for the AMS HT.
But i think it would be better to get a second AMS 2 pro, and have a seperate high temp dryer just sitting beside.
What do you think?
That’s exactly what I did. Got a second AMS 2 Pro for the second nozzle but also to have a second dryer/storage box.

This is also my way
2 AMS Pro (each on one nozzle) and min 1 AMS HT then in addition

Okay guys, thank you! I will do that. I will get a second AMS 2 pro… after i have the money for it.
I just had a great idea how to get one faster!
Do you think eating is realy that importend?
I could get the AMS instead…

The answer is always “both”. ¿Por qué no los dos?
Back to the Bambu store I go!

My plan is using 3 4to1 adapters fed into a hub. Or atleast 2 fed into a hub and the other going to the 2nd inlet of the printer.
I wonder what Bambu thinks is the best way of hooking it all up.
Figured there would be 2 hubs, since they also act as buffers

I think this is specifically why they aren’t talking about the AMS Hub. From what the documentation for the H2D it looks like the two inlets have the buffer integrated directly into them. You should only need an adapter(s) for the number of AMS you want connected to whichever nozzle(s); not a hub with a buffer.
You can connect the adapters serially per-nozzle inlet so you can connect a 4-to-1 adapter with 3 AMS connected on 3 of the inlets and a second 4-to-1 adapter connected to the 4th inlet for 7 AMS connected to one nozzle; etc. Bambu has several recommendations for different filament types as to which nozzle to use and how to feed the filament. So how you’d want to hook up multiple AMS units will largely depend on the types of printing you regularly do. E.g. if you just plan on using the AMS for multi-color prints with all of the same filament types then you’d probably want to somewhat evenly divide the AMS units with 2x AMS/AMS 2 Pro and 4x AMS HT on each nozzle inlets; with your various color filaments distributed between the nozzles to pair complementary colors across the two sets of AMS to minimize filament changes as much as possible.
Otherwise; you may wish to group multiple AMS units for filament types based on how frequently you print with the various filaments, following Bambulab’s recommendations as to which nozzle to use.

This is what I did too. Having an AMS2 per nozzle is really great.

Just for my clarification: The suggested setup with 2 AMS would be to connect them to each nozzle separately. When connecting a 3rd AMS you just plugin the 4-1 adapter and hookup the adapter directly and the nozzle input (externally )?
I am seriously considering buying a 3rd AMS2 Pro and want to be sure that the 4-1 adapter is all I need.
you’ll need the ams 2 pro power adapter, if you plan to use more than one of them as a dryer

Yeah, I’d recommend getting the power adapter for all of your AMS2 Pro units just to minimize the power draw over the bus cables and so you can use any of them in drying mode without having to plan around 1 unit at a time.

I am wanting to connect both my old AMS and the new AMS 2 to my H2D printer. I have the AMS 2 connected to the right nozzle. I want to connect the old AMS to the left nozzle. However, there is a difference in the cables for each AMS. the new has 6 connections and the old one has 4. I see that there are 4 of the 4 pin connectors and 1 of the 6 pin connectors. The instructions don’t say what the four pin connectors are for. My question is can I use one of the 4 pin connectors to plug in my old AMS for the left nozzle? TIA
4 pin are not used for h2d connecting to ams. Only 6 pin.
4 pin connectors on the h2d are for future use like hooking up an external air assist for lasering.
Ams all daisy chain off each other with 6 pin connectors
On x and p series printers, 4 pin cable was used to connect the ams buffer/hub. That is not needed with h2d as the buffer is internal.
Thanks for your informative reply. However, do you know if I can connect my old AMS to the left nozzle and if so how I can do it with a 4 pin connector?
