Lyngdorf Audio DPA-1 owner manual RoomKnowledge, RoomCorrection

‘Add more room meas.? Yes/No’ will show in the display:

•choose Yes to add another room measurement or,

•choose No to stop adding more room measurements. If No is chosen the volume is returned to the default or lower.

‘Save room measurement(s)? Yes/No’ will hereafter be shown.

•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.

RoomKnowledge

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.

RoomCorrection

The RoomCorrection index is a measure of how much processing is being employed in the room cor- rection filters. To some extent the RoomCorrection index reflects how audible the correction is. How- ever, the same amount of processing can sound very different due to placement in frequency of the processing. For low values (below 10%) of the room correction index, only subtle correction is needed to the original sound in the room. With high room correction index values more extensive processing is employed.

The RoomCorrection index for a specific RoomPerfect™ filter can be viewed by pressing the numerical button of the corresponding filter. This can only be done while in the RoomCorrection menu.
