Lyngdorf Audio TDA 2200 owner manual d. RoomKnowledge Index, e. RoomCorrection Index

Choose Yes to save the performed room measurement and No to exit without saving any of the performed measurements.

Adding one or more room measurements leads to a re-calculation of all filters (i.e. Global and all Focus filters) due to the fact that more of room’s acoustic properties have been learned, something that affects all filters.

The RoomKnowledge index is a parameter that tells how much of the room’s acoustical properties have been learned. A high RoomKnowledge ( ≥ 90%) means that most of the room’s acoustical properties have been learned. The more room measurements you add, the higher the RoomKnowledge will become. The more that the acoustical properties of the room are learned, the greater the accuracy of the room correction.

The RoomCorrection index is a measure of how much processing is being employed in the room correction filters. To some extent the RoomCorrection index reflects how audible the correction is. However, the same amount of processing can sound very different due to
