Do 802.11n (and older) devices slow down 802.11ac network?

Hi all

Currently I use my 5Ghz WLAN only for my Surface Pro 3 (802.11 b/g/n/ac).
All older devices use 2,4Ghz WLAN, to prevent the R7500 to switch to an older protocol.

Now I have two Amazon TV Stick's - 802.11 b/g/n; 2x2 MIMO (2.4 GHz and 5.0 GHz dual band) - in my 5Ghz network.

Question 1)
Will they slow down my 5Ghz 802.11ac network, so that the R7500 will run all 5Ghz devices in 802.11n mode?
Or can the R7500 handle "n" and "ac" devices in parallel without dropping performance for AC devices?

Question 2)
An does any 2,4Ghz devices affect my 5Ghz network at all?

I know that in older mix modes (specially with "b" devices), router uses the lowest common standard, but I don't know for newer "n" and "ac" modes.

Thanks in advance

It is only the wireless preamble that is affected by multimode/legacy operation, so your AC devices will not be held back in any significant way.
