    TC1 Dante Delay

    Hi everyone,

    We are attempting to use Dante as our primary source with the TC1 and we are having a problem with a fairly large delay. With our current Dante supported gear we have a latency of ~3-6 msec. But with TC1 there seems to be a substantial delay added. Below is a chart

    Source Dest Latency msec
    O1V96 TC1 70
    TC1 O1V96 103
    Tio O1V96 ~3
    O1V96 Tio ~3
    Tio TC1 70
    O1V96>TC1>O1V96 270
    TC1>O1V96>TC1 270

    The main takeaways are that when the TC1 is not involved latency is nearly impossible to detect. On the other side When going into the TC1 there is a 70 msec, and when coming out of the TC1 there is a 103 msec. When moving the same channel in and out or out then in of the TC1 it picks up a extra 100 msec of delay.

    All Dante controller settings are the same for our devices where applicable.

    Are you measuring these values in Dante Controller?

    We use an O1V96 for our own in-house Dante testing and have not run into this issue. Do you know if IGMP snooping is enabled on your network?

    No, We are measuring using a metronome from source to process and syncing them at the destinations output.

    I am not sure if IGMP snooping is enabled, I will check and report back!

    Have not used Dante as a source but I have found that going to the audio input and maxing out the delay, applying the config, then brining it back to zero lines thing up for me. I work with audio embedded in SDI though.
