Sq6 dante card to gld 112 dante card for FOH and monitor

Sorry for the stupid question , but for me is the firt time, if i want to connect my sq6 to gld 112 with dante…
the latency of 4ms declared from dante is for a single channale or for example for all 40 channel that i use?
Thanks

I found this questions and response in the dante faq

Does the number of devices or channels in use affect latency?

No and no. Adding new devices to a network does not affect the latency of devices already in the network. The latency of hardware devices does not depend on the number of audio channels routed, and routing additional audio channels does not change the latency of audio already passing through the network.
