Tvad...I still suspect that your clipping is internal to the DEQ2496 (clip limiter) as a result of equalization. A 16 bit digital word input really can't saturate a 24 bit D/A unless your processing has led to an output of more than 16 bits.
If this is the case output attenuation should resolve the problem.
I have not used the digital input because my multichannel discs don't provide anything but analog.

The output is not clipping, as would be the case if the DEQ2496 clip limiter was activated by over-boosting frequencies in the GEQ. I don't have any frequencies boosted very high, but perhaps later tonight I'll really jack up the 20hz band to see if the clipping is affected. In any case, if boosting frequencies causes clipping when using the optical input, this mitigates the usefulness of the DEQ2496, since boosting is required in addition to attenuation.
I have attenuated the output, and thus far this does nothing to change the clipping when the optical digital input is selected.
Nevertheless, this unit is fairly sophisticated to use, and I don't claim to know 15% of it's functions. One has to have a background in sound processing, or have a good tutorial to properly take advantage of the Behringer, IMO.
