The Preferred Curve Overlay is a valuable aid in the equalization process. It is the electronic equivalent of draw-
ing a Preferred Cure on the RTA screen with a grease pencil. The Preferred Curve provides you with an on-
screen target curve for equalization.
Step 1: To enter a Preferred Curve, tap the red PE
(Preferred Entry) stylus button. The Preferred Curve
Entry screen will appear: Step 2: Use the Joystick Left/Right, or the stylus to select
frequency (blue bar) and the Joystick Up/Down to set ampli-
tude until the curve entry is complete.
Step 3: Tap the “PT” Button to display the Preferred Curve
Overlay. To turn off the Preferred Curve Overlay, tap the
green PT Button. To edit the curve, tap the buff colored PT
button. Tapping the white PT Button will again display the
edited Preferred Curve. RTA LED Display
