The meters on Eclipse show dB, not dBu. dB are a relative measurement, in this case relative to the unit's peak level, which is around 25dBu. So 0dB on the Eclipse is around 25dBu.
One might wonder about this approach, but the engineers considered that a headroom measurement (meaning how far away you were from clipping) was more valuable than an arbitrary absolute measurement such as dBu. Maybe they were right, maybe not.
