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.
