Latency added with stagebox

[SebastienParticipant]

Hi ,
I’ve been searching in the sq section of the forum but found nothing about the latency added using stageboxes.

So, what is the latency we would expect if I connect an AB168, or a DX168, ar2412 etc …
Is there a chart showing this ?

Or is the desk automatically compensate the latency with audio connected on local inputs vs stagebox inputs ?

(For now I use the sq5 with a traditional 30 meters multicore patch 24/8)

Thanks !

Best regards

I found a small answer within dsnake specs, it’s like 105μs , a lot better than where I came from with behr and their sd stagebox’s 0.7 ms latency
So it remains the differences between the 96khz of DX168 and let’s say an AR2412 48khz, regarding latency Analog IN-OUT …

The A>D conversion takes time so adds latency. Whether that happens in the desk or 100m away in a stage box should make no difference.

So any difference will be to do with what’s in the box itself.

Pushing several realtime audio channels thru a basically serial connection like dSnake or DX will of course add latency to the whole system, unless you want each channel to have a separate latency and thus not being in sync with other channels.

Thank you, so do you know how much latency the stage will add ?

According to Allen and Heath here:
<a href=”https://www.allen-heath.com/media/DX-gigaACE-white-paper-1.pdf

States the DX protocol is running 32×32 channels over 100 Base-TX Fast Ethernet with a latency of 83us (microseconds). 1 millisecond = 0.001 microseconds, so 83us = 0.083 milliseconds.
Ad that to the SQ’s stated .7ms (Milliseconds) + 0.0083ms = .783ms, so even rounding up your at .8ms latency. Someone please check my math, but I think this is accurate based on
Allen and Heath spec’s they’ve provided.

[SteffenRParticipant]

only thing you mixed up is 1 ms = 1000us, I guess you would explain that 1us = 0.001ms
the rest looks pretty good

Dopf! Corrected copy….

😆
Thanks for the math (and spec’s)

Hi,
this is my result:

Analog Insert Latency (average) ?
