Note that the tint control is only available to composite and S-
video inputs; it is not available to component inputs (and should
not be needed for such sources, in any event).
Video filter
The video filter is a digital video noise reduction filter that is avail-
able on a source-by-source basis. It is most beneficial on sources
such as analog videotape that tend to be somewhat “grainy” or
noisy in appearance.
Despite sophisticated algorithms for reducing noise without losing
picture detail, there is always something of a trade-off in this
regard. Reducing video noise present in the picture almost always
brings with it the potential for a slightly “softer” picture. Try it both
ways, then decide.
Lock range
Digital video sources such as DVD and DV camcorders generally
have excellent “timebase accuracy.” That is, in terms of the video
signal they produce, they are extremely good at doing what they
are supposed to do, precisely when they are supposed to be doing it.
Laserdisc players and broadcast television are also usually quite
good in terms of timebase accuracy.
By contrast, analog video tape (VHS or Beta) suffers from stretching,
mechanical inconsistencies in the transport that moves the tape
past the video heads, and other problems.
The lock range of the video decoder within the Nº40 determines
how sensitive the decoder is to timebase errors. With excellent
signals such as DVD, setting the lock range to normal maximizes
the amount of information that can be gleaned from the video
signal. When watching a poorer-quality video signal such as that
from a videotape, setting the lock range to VCR makes the decoder
more tolerant of the timebase errors likely to be encountered.
Some video post processors (de-interlacers/scalers) have difficulty
with poor timebases on their component inputs. If you find that
your post processor has difficulty with the component output on
the Nº40 when playing a VCR, you will need to also connect the S
output of the Nº40 to your post processor and switch the post
processor when using your VCR.
Delete This Input
You can create an input and subsequently decide to eliminate it. Or
you can delete one of the factory-default inputs. To do so, go to the
input submenu and select the following menu item:
>>>>Delete this input<<<<
.
You will be asked to confirm your decision to delete the input. If
you are sure you want to delete the input, press enter to confirm. If
