CQ-18T

Filter Modes Fixed filters remain in place until they are manually deleted, the FBA is completely reset, or if the Feedback Assistant ‘steals’ them. Up to 12 of the 16 filters can be in Fixed mode, always leaving 4 for use in Live mode. Live filters recover over time and once fully recovered, will switch back to being unused filters. They can be deleted individually or with a complete FBA reset. All of the 16 filters can be used in Live mode. Automatic re-use of filters When all filters are already in use, but a new feedback frequency is detected, the Feedback Assistant can re-use or ‘ steal ’ an existing filter, using logic to decide the best possible outcome i.e. the least amount of feedback. Note that Live mode filters can only steal other filters already in live mode and Fixed mode filters can steal any filters. On power up Every time the CQ is booted, all Feedback Assistant instances are set to a ‘pre show’ state. Fixed filters, the Live Recovery setting , ‘All Filters’ settings and In/Out state are remembered from last power down. Any Live filters will have been removed. Detect Hold is active. Mode is set to ‘Fixed’ . Copy/Paste Copying and pasting includes all filters and settings (e.g. Live Recovery). This means that when pasting to another output (or back to the same output), the state of the FBA will be exactly the same. Store/Recall When using the FBA Library, Live filters are not stored or recalled. All Fixed filters, the Live Recovery setting, ‘All Filters’ settings and the In/Out state are stored and

can be recalled. Scene changes

Scene changes do not affect the Feedback Assistant settings directly, but they will usually change levels and processing which might affect which frequencies are more likely to feed back.
