3 Stacks, 2 PAs - how to patch this?

Hi

So this summer I have a “festival” for which the intention is to run two stages, but as they will be right next to each other, only use 3 PA stacks.

How would anybody go about sorting it so that speaker 1&2 are L&R or 2&3 are L&R?

I should have all 3 matrixes available, and probably 3 spare mixes after sorting monitors (From FOH desk, with iPad operator I hope).

Plan is for SQ to do main stage with a second desk (could be QU-PAC) running 2nd and sending its L&R to the SQ.

I can easily see how to do this if I run in mono, but can’t get my head around keeping it stereo.

I don’t want to alter patches between bands - but is that being silly?

Thanks

Hi Mark,

The only thing you have to do, is summing for Stack 2 the R of Desk1 and L of Desk2.

Desk1 L → Stack1
Desk1 R → Summing Device → Stack2
Desk2 L → Summing Device → Stack2
Desk2 R → Stack3

Better to do this Analog, eg that device is great:https://apb-dynasonics.com/product/mixswitch/#4

If you want to sum digital, be aware of the Latency, to stay phase coherent!!
So L and R have to go the same signal-path!

It should work with 2 matrix busses in SQ.
One Mono, one Stereo.

Qu L → ExtIn Matrix 1 → stack 1
Qu R → ExtIn L!! Matrix 2 → stack 2
SQ L → L Matrix 2 → stack 2
SQ R → R Matrix 2 → Stack 3

Cheers

Brilliant!

I’d considered analog summing, but had hoped to find a solution with no extra hardware.

Your second suggestion should work fine - I’d not considered the Extn In.

Many thanks ?
