Hiss on Audio Output of Kona 2
on Nov 21, 2006 at 6:11:21 pm

Hello,

I've only used the video output of my Kona 2 card until now. Yesterday I tried to monitor the audio output of my Kona 2 card and discovered that all I hear is a loud hiss.

I've tried 2 driver versions (1.x & 3.3), but that didn't help. I've tried both Apple's Soundtrack Pro & Final Cut Pro (5.1) and AJA's TV output program, but got the hiss on all three.

I was running the Kona 2 XLR cable into a Mackie mixer and also tried a Digidesign MBOX.

Anybody have any idea on why I'm getting a hiss, and how I might be able to correct this?


Thanks

We experienced an issue like that when we used the audio output for the first time.
For a long while we only used the video out just like you.

The trick is to go to the Mac's System Preferences - Sound and adjust all audio outputs
to 64. (adjust the audio level - then move the mouse away from it - then place on the
level marker again- a tip tool type window will pop up and give you the level number)

Hope this helps...

Thanks for the advice. Turns out the issue is that the Kona's connections are AES and not analog. I was trying to monitor via an analog source so that was my issue.

Yeah, that would be a problem.
Use the RCA outputs for monitor.
