On-Screen Messages

The front-panel display and video on-screen display may sometimes show these messages while you’re watching a movie:

•“Dial Norm Offset” (Dialog Normalization Offset): Once the C 1 is calibrated for your room and sys- tem, a volume setting of “0” will give you the same sound levels in your room that you’d hear in a commercial movie theater – assuming that the dialog in the movie was recorded at the correct level. The “Dial Norm Offset” message, which flashes briefly on the built-in display and OSD at the beginning of a Dolby Digital DVD, shows you to what extent the dialog on that DVD deviates from the standard. For example, if the dialog offset is +4 dB, that DVD’s dialog was recorded 4 dB too “hot.” Reducing the C 1 Controller’s volume setting by 4 dB will restore normal overall levels.

•“Digital Error”: The digital signal being fed to the

C 1 has errors in it, and the C 1 needs a little time to analyze and accept it. This may happen very briefly at the start of a DVD or CD and for longer periods when surfing channels with a satellite receiver. While this message appears, you won’t hear any sound; so a slight delay whenever you tune your satellite receiver to another station is quite normal.
