REMOTE UNIT CONFIGURATION & OPERATION
29
4.2 Video Adjustments
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 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 both video channels simultaneously (dual-
head units only).
To get the best video image, you are recommended to follow the procedures for manual fine-
tuning (see Adjusting Video, page 31).
