Advice on Line delay

Any advice on delay line used to sync audio to video for live recording
Any specific parameter or function to watch for

Any decent digital audio mixer should be able to add a delay to any of it's independent outputs. They usually go up to 250ms or even more. That's roughly 15 video frames at 60fps or 7 video frames at 30fps.

Hi Marco.

As you said many devices can offer delay. But I wonder if products from video manufacturers (AS22S Rane, VA-256xl Kramer...) have something more than common delays.

What more do you want?

Both devices that you mention seem to be able to delay the audio and could be be a good solution in case your audio mixer does not offer that possibility.

devil is in the detail

You put an end to my interrogation : If video manufacturers offer the same delay (and functions) as audios manufacturers my UI24 mixer will be enough

Not sure what you mean... A quick glance at the manual of that mixer shows that it has a delay function on the MAIN L and MAIN R outputs.

In short, if delay products sold by video manufacturers do not have specific functions (as you said), I will use delay included in my mixer

thanks for your advice.
