MID
RANGE BOOST/CUT CONTROL 1 AND 2
This control works in conjunction with the SWEEP frequency control. The MID and
SWEEP controls work together to provide a semi-parametric tone control. When the
MID control is set at 12:00 straight up there is no boost or cut in the MID frequency
portion of the spectrum. The graph below shows the response of the MID boost/cut
and SWEEP controls. The MID control /- 12db of boost or cut to be applied
at the frequency determined by the SWEEP control.
SWEEP FREQUENCY CONTROL
This control works in conjunction with the MID boost/cut control and adjusts the
center frequency of the MID boost or cut signal. At the full counter clockwise setting
the midrange 1 frequency will be at 60Hz, at the full clockwise setting the center
frequency of the midrange will be at 1.2KHz. Midrange 2 will sweep from 250HZ to
6KHZ. NOTE: when the MID control is set at 12:00 straight up the SWEEP will not
have any effect on the signal since there is no boost or cut being applied.
TREBLE CONTROL
The TREBLE control adjusts the boost or cut that is applied in the high frequency
portion of the spectrum of the PREAMP. The available TREBLE boost and cut range is
+/- 15 decibels.
