AES output noise
by Ernie Santella on Oct 29, 2008 at 7:45:40 pm

OK, I'm getting some crackling sound out of the AES/EBU digital out on my Kona 3. Nothing changed. Any idea why?

And just curious, what are you guys using as a D/A to monitor audio? I'm using a Midiman Flying Cox 24bit D/A.

That's what I used to use before we got out littel machine room.

What' your refrence set to on your Kona? What format is your timeline? And what else is your Kona hooked to?

Jeremy,

I just started getting this noise. I've trouble-shot the Flying cow and it's fine with other sources. So, I'm narrowing it down to the Kona or FCP.

Specs of the current project are: DVCProHD 720p/60 timeline. 48KHz, 16bit depth audio. What do you mean by "reference set to"? I'm feeding a BB generator into the Kona ref in.

In the Kona control panel, is Ref In set to Ref In, Video in?

At any rate, try setting it to free run.

Just tried the Free Run option, no dice. I think I have it narrowed down to the FCP as if I use the Audio tool window and lower the master output, the noise lowers, but does not go away. It's not on my tracks as they are clean. I'm going to try trashing preferences next.

No, it's not on your tracks. This has to do with the Kona and it used to have to do with reference.

Trashing Prefs didn't solve it. OK, Is there a way to reset the Kona? I recently did do the Flash firmware update.

Uninstall and reinstall the Kona drivers.

I've done that too. I spoke with Aja and think it might be the card. They are sending me another Kona card to test at No charge. Now, that's customer service!!! I am so glad I bought the more expensive Kona instead of one of the other companies. They have excellent customer service.

If the noise lowers when you attenuate the faders then it certainly is not a reference issue. Reference clashes will cause crackles at a constant level regardless of the fader positions.
