A small unmanaged network switch like this will do just fine for your application. However, if you are getting Axient Digital and there is any possibility you may use the Dante network audio functionality in the future, at least a very small step up might serve you well.
Simple Dante networks don't need anything fancy in terms of switches - but you do want to be able to turn green-Ethernet off, which you can't do on most of the very cheapest switches. Just a few dollars more will get you a netgear switch that will do that. This one can disable green-Ethernet, has a few extra features you might find a use for someday like VLAN, and is still under $50.
