Note: The Loudness Compensation Range is a combination
of the Loudness Circuitry and the Volume Control’s
rotational position. When the Loudness Circuit is
active, the first 50% rotation of the Volume Control
achieves maximum loudness compensation, as shown
on the upper curve. When the Volume control is rotated
beyond the 50% point, the loudness compensation is
gradually reduced, as shown by the remaining curves.
