AJA and FCP5 audio output sounds overloaded
We are editing opera with 24 tracks of audio in FCP 5 with AJA IO board using G5 dual 2.7. We imported the audio files from our audio engineer (sound design files) synced and everything was fine. Problem is in some places it sounds overloaded, all though none of the meters show overload. We thought it might of clipped during recording, but then when we played back our project bypassing AJA board and playing through firewire deck, everything sounded beautiful, with no overloads. My guess there is some kind of setting with AJA board we are missing? or our AJA IO audio processing is bad? Any help would be appreciated.
Thanks

I noticed the same thing with the audio outputs from the IO LA box. Although the levels “looked” okay, the were overmodulated and distorted.
I ran the audio outs into a line-level pad (-50dB attenuator, the little Shure A15LA), changed the trim on the mixer inputs, and all sounds great now.
I believe there’s a software switch on the new IO Control Panel application where you can vary the output levels as well.

Thank you for your response, any one knows where that software switch on the new IO Control Panel to switch audio so it won’t overload?
thank you in advance,

I was running a thread on this a few weeks ago. The IO definately increases the output level by a considerable amount. The new driver Version 2.0 is available on the AJA web site. When you open the Pro IO control Panel you can click on the ‘control’ tab and there you can select +18dBu or +24 dBu for analogue audio settings. I didn’t find that it made any difference. Maybe someone from AJA can shed some light on the analogue output of their IO and why it is increasing gain by so much?
