What is the maximum concurrent users for Edimax BR-6475nD

Hello,
I just wondering what is the maximum concurrent users for this router Edimax BR-6475nD
I know that this router is a concurrent dual band with 300mbps speed
My question is what is the maximum users for each band?
I have never found an answer to my question in the user manual!
 
So this is a 2x2 on each channel. What that means is a single device can communicate on each chain independently. So 2 devices can be sending and receiving simultaneously assuming that one is on 2.4GHz and the other is on 5GHz.
