‘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 fi lters (i.e. Global and all Focus
fi lters) due to the fact that more of room’s acoustic properties have been learned, something that affects
all fi lters.
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 fi lters. To some extent the RoomCorrection index refl ects 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 specifi c RoomPerfect™ fi lter can be viewed by pressing the numerical
button of the corresponding fi lter. This can only be done while in the RoomCorrection menu.
