SQ/Ava-Core would be the best option in my opinion.
Format 1U
Back panel:
2xXLR out (LR/control room)
1x AES/EBU out
1x AES/EBU in
2x Slink
1x Option card slot
1x eth control
1x powerconn T1
Front panel
1x 3,5mm jack in
1x “TB” mic pre in with Talk button
1x headphone out with knob
1x USB slot
4x micro-soft buttons
1x soft rotary
Soft off-button
Option to have it as have it as brain on stage for Avantis/SQ to have failover redundancy as DLive. Or even to use it with dLive as failover with limited procesing when on ultra small gig with only small stagebox DX168.. 😉
MSRP: start @ 1500 Eur up to 4000eur? (depending on configuration of processing core, plugins and or redundancy package), would be insta-purchase.
