I recently had to setup an X32 with 2 S16 stage boxes.
Used AES a on S16 1 and connected to S16 2 AES A via the AES B out of the 1 st S16.
Set up was 1-8 on S16 1 and 9-16 8+ on S16 2.
All 32 inputs and 16 outputs to show up in the right places.
However...Desk channels 1-16 showed input control as "gain" with phantom power control via the desk but 17-32 showed as "trim" and phantom power was not controlled via the desk.
Audio passed on all channels and I was able to do a show but could not figure out the trim vs gain.
Thoughts or suggestions?

Did you try swapping the boxes and/or cables?

[John P. Farrell]

It is my understanding that with the latest firmware "B" output is trim only....this is so A can always control the head amps in a situation where two consoles are sharing stage boxes.  It has caused me frustration in the past.  Also, only the console connected to "A" can use the outputs.

No time on the gig but will try in the shop.

I'm sure I used this setup a few years back and all channels were "gain".
All 16 outputs were working correctly.

My money's on a bad cable between the two S16's.

You otherwise connected everything correctly and it should have worked.

That video was put up in 2014 and doesn't include Ethercons, which is misleading in terms of "best practice" and a recipe for eventual trouble.

I think there's also something hinky in how they are showing the console output settings but don't have time to confirm my thought.

That seems like a very odd update. I'm still on 3.09 and have a DL16 and a S16 and have full control of both boxes as far as gain control.
My DL16 takes A AES50 in and sends 1-16 channels to the desk. B AES50 out to the A AES50 in on the S16.  The B out on the DL16 is only to pass the A AES50 channels from the S16 on down to the desk.  I have the 1-32 channels all patched to AES50 (A) stream from the 2 stage boxes and they all work great. The B out on the DL16 again just passes 17-32 AES50 A on from to the S16. The stage boxes automatically assign channel order number according to the hookup order.
Something doesn't sound right. I'll ask around.

Any chance you went out the first S16's B out and went into the 2nd S16's B in? This may cause this.

This is the video I used to configure the setup.

I thought I had it patched correctly but I may have made that error. However, would the outputs work correctly if patched to the B input of the second S16?
Something to check when we configure in the shop to test.

I asked a few people and they said you'd only have Trim control. Others said they had no idea.
I'd hook it up in the shop and try both. So long as your using the right cable, Cat5e with bonded ethercon ends it should work as in your video.
