mi autorispondo.....
leggendo bene il manuale trovo:
"GROUP DELAY: Also known as "lip-sync" delay, this setting delays the audio signal for an input by the specified amount to match the video input. This feature can be useful when the video signal is delayed more than the audio signal as sometimes happens with upconverted digital TV processors or when trying to match a radio broadcast with the video from a sports event. The range of available settings is from 0ms to 500ms, in 5ms increments. The setting is individually
stored for each input and is the default group delay each time that input is selected. The setting can be temporarily overridden from the front panel or the remote."
cioè così
"Like the speaker settings, this is a temporary adjustment that overrides the permanent default setting for a video source until a different input
source is selected or the unit is turned off. To adjust group delay using the remote:
1. Press the C button on the remote twice.
2. Use the UP or DOWN buttons on the remote to adjust the amount of delay applied to all channels."
quindi TUTTO OK !
l'ultimo dubbio è se il rotel 1068 è un buon prodotto e vale i soldi che costa..... cosa ne pensate....
