This filter is designed to remove the horizontal scratches caused by damage to two inch tape The filter works by looking for the periodic characteristics of this defect to differentiate between the scratch and picture detail This type of defect can also affect the pedestal level of the picture Enhancer Enhancement is concerned with the sharpening of certain features such as edges and textures and is employed to improve the visual appearance of the pictures The Archangel Two features an advanced linear luma enhancer Key Archangel Two provides up to four user definable rectangular keys that can be used to restrict the range of detection and concealment of the Dirt and Tramline filters The keys are prioritized to allow overlapping and more complex shapes if necessary and are directly accessible from the front panel Version 1 Issue 4 7 6 Archangel Ph C APPENDIX Archangel Synergy Troubleshooting Guide Introduction This is intended as an aid to troubleshooting control problems between Archangel and Synergy Before you start make sure that the system is set up correctly all signals are connected correctly and all hardware has powered up correctly This guide is split into three parts Section 1 simple trouble shooting guide Section 2 basic things to test and check Section 3 advanced things to check Section 1 Troubleshooting 1 1 Can t control Archangel 1 and Archangel 2 2 1 Syncs 2 9 TDLAN 2 6
