Not sure if your talking about SQ for FOH and another for Monitors but this pdf guide shows how to run 2 SQ’s for that, but you need a slink card in the Monitor console.
Thanks for replay you right was FOH and Monitors we’re having trouble how see the channels on both mixer we using 16 channel as local and 32 channels from 48X16 or in one mixer but not on the other 😢
You can always start a ticket with Allen Heath support. The Guys there are fantastic to deal with and will most certainly get you sorted out. https://www.allen-heath.com/support/
Connect GX4816 to Monitor-console. Then use Tie-Lines to route the channels to the FOH-console. Monitor-console needs an additional S-Link-Card.
There are videos from Allen&Heath regarding using Tie-Lines.
