AJA TTap
on Nov 1, 2015 at 10:38:36 pm

Just got one for my iMac.
It is working,but I have lost my audio output from iMac, it now follows the HDMI signal to the monitor.

This is a consumer Samsung and consequently not the best sound.
I need to restore previous routing, which was taking audio from headphone output on the Mac, and sending to an amp and superior speakers.

Has anyone figured how to do this?

Sorry...can't. Once you hook up IO to the computer, Avid sends audio to it...period. You cannot tell Avid to send audio to the computer headphones. You'll have to get a mini converter box, Blackmagic has an SDI to audio one for $200.

If the Samsung doesn't have an audio pass through, you could try something like this.

HDMI audio deembbedder. Has a headphone jack and video pass through to your Samsung

Thanks guys.
The audio deembedder could work, otherwise I return the AJA
and cough up for a Matrox box, I guess. I believe it allows
audio monitoring, although don't have it right in front of me.

The monitor does not have pass through unfortunately.

Note that Matrox will stop supporting MC for its products. May not be the best investment.

Yikes, good to know!
Any strong recommendations from anyone, as to alternatives?
I know there is AJA and Black Magic, and would like to stay
in same relative price range as the Matrox box.

Matrox support for Avid lately is spotty. I'd look at Decklink options.

Shane,

This is for my iMac, so cards are not an option. I was thinking Intensity box for Thunderbolt from BM Design.

So, I just heard back from BM support.
They tell me separating audio and video via HDMI will cause sync issues. Which sort of defeats the purpose of their Avid approved Intensity I/O solution, doesn't it? The signal travels from the Mac to the box via Thunderbolt, I thought to monitor video from the HDMI, audio from the RCA audio outs.

If indeed that is true, I imagine the de-embedder suggested earlier with the AJA TTap would also be a problem.

How do you guys deal with this?

I have the AJA IoXT, and now the Decklink UltraStudio Extreme 4K. I send picture to the monitor via SDI, and monitor audio from the phono outs on the AJA box...and the RCA outs on the BMD unit. Interestingly there is a one-frame difference between my PROGRAM monitor in Avid, and the external monitor. On both units. I hear this mainly when I monitor both the audio from the box directly, and from the monitor that has audio outs. I tend to monitor audio from my broadcast monitor...loop through. Although it isn't too bad the other way...I mainly do that for client review.

So I guess my solution is that I have a broadcast monitor with loop through. An FSI monitor. But there is a console command you can type in to offset the sync difference.

moncondel 2

You'll have to type that in every time you open your project

Thanks Shane.
I don't have the budget or gear options
working with an iMac.

The search continues.
