QU6 won’t connect to GX48. The mixer says “Dsnake” on the display, but the mixer doesn’t link to the GX48, so no inputs or outputs are detected. We’ve tried different cables and firmware updates. We don’t know what the problem could be.
Not sure if the sample rate on the console is changeable, but can you check that it is set to 96KHz, as that is the sample rate that the GX4816 needs the conosle to be running at.
It is not possible to change the sampling rate - QU2.0 consoles always run at 96 kHz.
Did you connect the SLink port of the QU-6 to the GX port of the GX4816?
And did you wait a while after connecting the device to allow the system to perform any necessary firmware update of the GX4816?
DSnake is the “older” 48kHz protocol that has more limited bandwidth. The GX4816 does not use that protocol for it’s connection with a console. It uses the GigaAce protocol which has a lot more bandwidth which is required given how many inputs and outputs the GX4816 uses.
If your console shows “DSnake”, then it will never connect to the GX4816. I am not sure why the two devices would not be communicating with each other through the initial “handshake” where they would negotiate the correct connection type.
I would suggest moving the GX4816 close to the console and using a short network cable that is know to work correctly at 1gb speeds (or faster) to connect the stage box to the console’s SLink port. If that doesn’t work, then there is something wrong. If the console works when connecting other devices to it’s SLink port, then the issue is with the GX4816. On the other hand, if the console won’t connect to other “non-DSnake” devices, then it’s something wrong with the console or SLink port in the console.
You might want to reach out to A&H via the official support methods (found on the main A&H website). They might have some other troubleshooting methods that you can use.
Hi Brian,
the GX4816 does support the DSnake protocol through the ME port…
Perhaps the OP has connected the console to the ME port on the GX4816 by mistake and therefore only gets DSnake connection. Unfortunately the OP has not responded to any answers provided.
While the GX4816 might use the DSnake protocol within the device itself, but it does not, nor can it connect to a console over the DSnake protocol. That was the point I was trying to convey, but as you pointed out, my post could be written a little better. I’ll edit it to remove any misunderstanding.
I also didn’t make my point properly as well… It is possible that it would show as DSnake but still could not connect to the GX4816. We are on the same page… 
The mixer used to work through the “gx” port. This phenomenon of not connecting has occurred recently. It worked in 2025 and we used it like this. It has not worked for a few weeks.
