Remote Unit Configuration & Operation 25
Video Adjustments
SDBX Remote Units feature a number of correction tools to simplify video
optimization. This procedure is straightforward and only needs to be carried out
once.
For each video channel, the Remote Unit allows you to optimize independently:
• Low frequency (LF) equalization
• High frequency (HF) equalization
• Red delay
• Green delay
• Blue delay
To help automate the procedure, the SDBX Remote Unit offers the following
unique tools:
• Assisted EQ: Allows you to ‘step-through’ a table of preset LF and HF EQ
values for different cable lengths.
• Quick Skew: Inserts a standard delay on a specified color (19ns - a typical
value suitable for most applications).
• Channel 0: Allows you to apply video adjustments to all video channels
simultaneously (multi-head units only).
To get the best video image, you are recommended to follow the procedures for
manual fine-tuning (see Adjusting Video, page 27).
