Shure P300 is only really good for very small rooms.? It's more of a usb sound card with a little bit of processing rather than a full blown Dsp.? Good for a small conference space but I wouldn't attempt any kind of room linking with it.? Way too limited.?
QSC is by far and away the best and most capable dsp on the market.? Be it a Core110f or a Core 8 Flex.? Depending on the amount of IO you need.
Aside from QSC, you could also look at the Biamp Tesira range.? Again, depending on the amount of IO you need (analogue IO I mean) you can either look at the Tesira Dan range or even the X400/800 range.? Side note with the Tesira...?
The larger Tesira Forte models (older range) have much older usb hardware and as such, don't support some of the USB control comms with the UC device.? Meaning, you won't have programming access to usb mute, volume, on/off hook functions.? The newer X400/800 models do support these features.? If you need that.? It's quite handy to show mic mute states on ceiling mics or touchpanels when someone presses.mute in Teams or Zoom etc.??
My strongest advice, is to stay as far away as possible from the Clearone Converge 2 range.? You can pick them up at reasonable prices but there is a good reason for that.? Nobody wants them.? I've made it pretty clear to my superiors that the next one I see on a job will be taken home with me and thrown in to my fire pit at home.? WORST DSP on the market.? Even worse than BSS Soundweb
Bottom line,?
QSC - run towards.?
Clearone - run far far far away.?
