Audio to hot during capture
Hello,
I just bought my AJA IO recently and I love it, the only problem I’m encountering is that all of my audio is coming in to hot, about +18db to hot. I have looked all over to try and find where I can lower the incoming audio, but I can not seem to find an option. I’m sure it’s soemthing simple, would some one here be able to let me know how to fix this.
Thanks,
Shane -

What source is your audio coming from, and do you have a mixer?

The source is both mini DV and Hi8mm both coming through the stereo RCA cable.
Sorry, no mixer, never needed one with my Cinewave card, do I need one with
the AJA IO? -
It would be advisable as you are coming out at consumer/rca level and need to get your audio to line level. A cheap mixer will do this very well. Wait until Bob Zelin sees this and you’ll know what you need.

Shane –
I have installed countless Pinnacle CineWave systems, and EVERY DAMN ONE OF THEM had an audio mixer on it. There is no way to route, amplify, and attenuate all these different analog sources (from +4 to -10 dBu) without a bunch of balancing amps (which just cost too much money) or a CHEAP MIXER.
Many people use inexpensive Behringer mixers that range from $50 to $299, which work teriffic for this application. You can also get more expensive mixers from companies like Mackie, Soundcraft, Yamaha, Allen Heath, and so many others. You can contact your dealer, order mail order, or just go to your local music store – mixers are EVERYWHERE – and YOU NEED ONE. This will resolve all of your problems, and had you bought one for your Pinnacle CineWave system (like everyone else did) – you could still be using the SAME MIXER – becuase unlike these Mac computers, the mixers DONT GET OUTDATED and are very useful, no matter what comes out.I am VERY SURPRISED that you are saying that your signal is TOO HOT. The output of the Mini DV and the Hi8 mm are both -10dBu, and the AJA I/O expects to see a +4dBu signal, so your “zero level” should be 14db TOO LOW – not high ? If you are trying to layback to your Mini DV, or Hi 8, THEN the signal will be TOO HOT going into these pieces of equipment.
Your Pinnacle CineWave Break Out Box had XLR connectors on it, just like the AJA I/O does. The output of the AJA I/O is no different than the Pinnacle CineWave. +4dBu.
Buy a mixer (or get some line amps).
