thanks for all your assistance.

Yes, I haven’t maxed everything, but gain, level and mix is all just shy of max and it is registering on the io HD meters, but not very high. Just like FCP–it is moving, but not anywhere near where I would expect.

Hopefully the AJA people will have some ideas.

thanks again.

yep–I’m capturing audio and video.

Here’s the control panel:

The video runs from the camera into the io HD via component.

I changed the master gain in clip settings to 1. Tried again and no change.

Here’s my Behringer FWIW:

[Scott Phillips]

yeah, I think I tried that before–I tried it again to be sure, and there is no change.

If I tap the mic, I might rise above -42.

ok–here goes.

I’m testing a wireless lavaliere mic–I’ve also tested a Shure SM7B with the same results–and the transmitter is plugged, via XLR to the “line 1 in” on the Behringer. I have the Gain and the Level knobs at half-way between min and max. I have the main mix slider around -10.

I’ve plugged in headphones to the “phones” jack to monitor and it sounds as I expect it would. I can clearly hear myself speaking as well as lots of ambient noise with everything set this high. The meter on the mixer will register -20, but never up to 0 or closer to being “clipped.”

From the mixer, I have two 1/4″ to XLR cables that go from the “main out” to the “in 1” and “in 2″ XLRs on the io HD. As mentioned before I also have analog video from a Panasonic HVX200AP connecting to the io HD. I plug in the headphones to the monitor RCA on the io HD and it is much quieter when compared to what I hear when monitoring on the mixer.

Then, naturally I have the io HD connecting to a 27” iMac via FW 800. I’m using the easy setup in FCP=AJA ioHD 720p 59.94 Apple ProRes 422 (HQ), with audio settings of 48 khz, 24-bit and “config” set to “channel grouped.”

When I use log and capture, I go to the clip settings, where I monitor the sound there (Preview is checked). And, just as it is monitoring on the io HD, it is much quieter.

Once I stop and review the footage, the audio waveform barely registers anything and my sound is around the -60 on the meter.

So, it seems to me that something is happening at the io HD.

Hope this is helpful–please let me know if you need anymore info on the setup.

thanks again for your help.

OK–Jeremy. You’ve been a great help, and I hate to prolong this thread, but I have more questions.

We purchased the Behringer mixer, but I’m having the same results. I crank it up and listen through the monitor on the mixer and it sounds as it should–loud, hiss, lots of background noise.

But when I go to Log and Capture and capture the audio, it is very low. I check the “preview” box to monitor in FCP and it is way different than the monitor on the mixer–much quieter.

Do you have any thoughts on what the io HD may be doing? Or perhaps FCP? There is very little in the documentation (io HD) about audio settings. But, I think I have everything configured properly.

But, evidently something isn’t right.

I’ve tried some other mics (previously, I’d only tried Shure sm7b) and I am getting some better results. Phantom power is on–by default–at the mixer. And the level is being controlled by the mixer.

Still seems significantly different when monitoring the mixer as opposed to monitoring in FCP. The max output level of the mixer is +14 dB and the max gain is +55dB, FWIW.
