    The processing delay for all MOD-JA-ALC-N-YYY modules is ¼ of a video frame. To compensate for this processing delay, the user must increase the processing delay of the card by +1 frame. This additional processing delay must be added manually in the Video Output page under the Timing tab. FRS-3901 | 93...
