of the band of frequencies centered at the frequency
marked above the controls. The center frequencies
of these controls are at 25Hz, 50Hz, 100Hz, 200Hz,
400Hz, 1,000Hz, 2,500Hz and 10,000Hz. Both Left
and Right Channels are affected. At the center detent
or flat position of the controls, the tone circuit compo-
nents are removed from the signal path.
The illustration to the right shows the fundamental
