Input mode
The TANDEM 3G has the option of either receiving an optical input or transmitting an optical
output once the necessary SPF optical module has been fitted. If the optical receiver module is
fitted the fibre optic I/O input select will allow the video input to be selected between the input
BNC and the optical input.
With the optical output fitted the number of outputs will be reduced from two to one.
Video timing controls
The video delay is a straight forward fixed video delay that can be adjusted in whole-frame
steps. Additionally the minimum delay through the board can be set.
The selections are;
Audio to be 3 milliseconds and Video 4 lines.
Both to be equivalent to the minimum audio delay of 3 milliseconds.
Both audio delay and video delay exactly 1 frame.
Any user selected delays will be in addition to these settings.
Video gains
The video proc-amp allows adjustment of video gain, black level and independent YUV gains.
The maximum increase in overall gain allowed is 200%, should any combination of controls
be set where this maximum would be exceeded the gain will be limited to 200%
Note:
It is possible to set the gain control so that their combined indicated gain will exceed 200%.
In these circumstances the indicated values will not be valid.
