Now here's something very scary.
It is a friend of mine who found out about the following, but I checked for myself and it is true...
Create a new session in 24 bits resolution, let's say 8 tracks if you have a 192 interface. My session was in WAV format, running at 48kHz.
Arm all eight tracks from inputs one to eight.
You need an external tone generator with plenty of gain (we both used our console's 1kHz generator with an outboard SSL XLogic channel to get enough clean gain in order to reach 0dB full scale. I also need you to monitor the ouput of your system.
Feed the 1kHz tone to one input at a time, crank up the gain, until you hear it distort. Check the session meters. Do this for every single input.
Strangely, you will find out that several inputs out of 8 will distort before turning red on the session tracks meters. The other ones will distort once you're in the red. If you switch the track i/o volume window to peak, you'll see that it distorts once you hit 0dBFs. (That's reassuring) but on the misbehaving tracks, it takes a whole lot of gain before you hit the red "led". On the other hand, if you look at your 192 interface meters, they all turn red when they should (once you hit full scale).
This is very annoying. Let's say you're tracking drums, with a whole bunch of tracks. Sometimes, you need to trust the meters, because distortion can be hidden in the tracking mix, or happen on one hit on the whole take, right? Well, you might be hitting full scale and beyond without the tracks turning red!!!! How can you trust your system then?
I'm wondering if someone else has witnessed the same thing out there. I did not checked other interfaces myself, yet. My friend says the 96s inputs are responding ok. I wonder about the 888s, Digi001 and 002,...
Is this a bug? It seems that there is a problem of communication between the software and the analog inputs of the 192 interfaces...
Amptec, one of the most serious Digidesign dealers in Belgium has been kind enough to swap interfaces, just to make sure we did not have faulty hardware. They also personally recalibrated the interfaces. It does not make any difference. One more detail : each 192 interface has a different set of track measuring wrong... hihihi...
Oh, and I forgot, I tried this at 16 bits and the system works fine...
Time to do a little research for yourself and share...
Can't wait for your replies. Good night!
