Loudness Boost
1. The loudness boost is automatic.
For the first 1/2 rotation of the
volume control, the loudness cir-
cuit is active and will boost up the
low range (100Hz) and high range
(10Khz) to compensate for the
music tones that are not normally
heard at low volume listening.
2. After the volume control is rotated
past the 1/2 way mark, the loud-
ness effect will diminish as at these
higher volumes, the boost is not
needed.
