Trelja...It took me months of fiddling around to learn how to set up and use the DEC2496. And I are a engineer!
The line level setting is one thing that I found very important, but which many users probably don't bother with. You can monitor the input (electrical) levels using the METER mode. It will, among other things, log the maximum level seen during the course of playing a CD. The procedure I used is as follows. It applies when the Behringer is between the preamp and the power amp, and is cited to illustrate the basic idea. (If you use the digital input this may not be necessary).
1..Mute, or turn off, the power amp.
2..Play a CD that includes some loud parts. (I actually used a test CD put out out by Denon that includes test signals at specific levels like -20dB).
3..Crank up the volume control until the level runs around -20 dB on the green LEDs. (Remember this is dB down from the 0 dB reference). If you use the Denon test CD this -20dB setting can be done exactly.
4..Back off the volume control a bit, and then turn up the power amp gain to what you think is loud.
In my system this setup procedure results in typical music signal running about -20 dB much of the time, and the peak for a whole CD being -6dB or less for both channels. I never see CLIP. However you do the setup, this should be the goal. The basic idea is to make the MSB (bit 16) of a CD correspond to the MSB (bit 24) of the Behringer. Hopefully this will happen automatically if you use the digital input.
