E to E direct question at DVinfo.net

Hi all,

Just a quick question - is there any consequence from leaving E to E direct turned ON all the time?
Is there any reason why you would turn it off?

Just wondered.

Thanks

Funny you should ask Dave. I just had this conversation. The one case where you would want it turned off is if you are embedding analog audio into your SDI stream inside the unit. You would also want that analog embedded audio to be present at the SDI output and since the E-to-E does not have enough time to do embed and low latency output, then you would want it off.

You would also turn it off if you didn't need it on.

So I guess I would ask the question the other direction. What are you trying to solve by turning it on?

It may be useful when recording and monitoring, to avoid the audio delay in the headphones.
No latency (but not sure)..

Also you would turn it off if you needed to alter the PSF of the signal. Meaning, as an example, you need PSF in but not PSF out.

E to E direct makes the output look just like the input so if you have E to E on, and you have PSF in, then you get PSF out too.
