wahlerstudios wroteA configuration 64S/32R/32R means 64 input channels and 32 mix outputs. The rack mixers or the NSB stageboxes will NOT expand the input or output configuration.
I don't think that is correct. A 64S/32R/32R network allows you to run the 32Rs in stand-alone or monitor mixer mode. That gives you up to 64 mono aux mixes for the 48 physical mix outputs on that network. Add an NSB32.16 (or two of the other NSB models) and you'll have aux outputs for all 64 aux mixes.

As for inputs: A 64S+2x32R or a 64S+2xNSB32.16 configuration gives you 96 mic/line inputs on the network, and 2 stereo aux inputs. The limitation you'll face is the maximum number of inputs any given mixer on that network can use at the same time: A 64S is limited to 64 inputs, a 32R is limited to 32 inputs (plus a few for the stereo Aux inputs).

The 64S has 32 physical mic/line inputs and 16 mix outputs, so it needs a 32R in Stagebox Mode or a NSB 32.16 to add analog inputs 33-64 and analog mix outputs 17-32. And of course, more 32R can be added in Stand-alone Mode for more 'local' input and output, but if the intention is to use inputs and outputs in the network configuration, the 64 AVB input sends would be 'occupied' already and there would only be 32 AVB output sends left. Theoretically it should be possible to use AVB sends 33-64 for the two Stand-alone rack mixers and some EarMix 16M, but I don't think that the goal here is to create more 'islands' again. The 64S can handle 64 inputs and 32 mix outputs, anything else is an 'island' solution, which is not ideal for live situations.

There is hardly a thing like 'an island' on an AVB network. Every input device can broadcast its inputs and mixes (up to 64 channels in total per device) on the network. So a 64S can send out its 32 mic/line inputs together with say 30 of its aux mixes plus main out for 64 channels in total, stage boxes will send out their mic/line inputs (twice, for GC too) and 32Rs can send out their 32 mic/line inputs and 16 aux mixes with 16 AVB channels to spare.

From all those maybe hundreds of channels on the network every listener device can select the 8 streams of 8 channels (2 streams for EarMixes) it wants, e.g. to create mixes for sending out on the network and/or for local outputs. The 64S can mix 64 channels (plus a few aux inputs, and local FX) and most of the other mixer models can mix 32 channels (plus a few aux inputs, and local FX). And submixes can be shared on the network too, if the 64 AVB sends per device limit permits.

So each 32R in the 64S+2x32R network can be given access to all mic/line inputs and (sub)mixes locally and on the network, from which they can select a combination of 38 inputs (including 2 aux inputs and dig in) for creating aux mixes on the local outputs and for sending out on the network. Extremely flexible really :)
