The following code changes were made from ver 2.5 to create 2.5E of the
Signature 2.0.
1. When powering up main, initialize the video chip correctly to display a Blue screen
rather than black.
2. Correctly set mixer latches when toggling between Stereo and any matrixed mode.
The following code changes were made from ver 2.5E to create 2.6 of the
Signature 2.0.
1. Added menu entry in “Source Menu” for Video Detect. This allows the user to
configure each individual source to switch to a Blue Screen when a loss of video
sync pulses is detected, as in the default or “Auto” mode, or disable the detection
altogether in the “Off” mode. The “Off” mode is useful when a video source is used
that may exhibit video sync pulses that may be too weak for the Signature video
board to deal with correctly, causing the Blue screen to appear rather than the
selected video.
