5. 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 frequency will be at 300Hz, at the full clockwise setting the center
frequency of the midrange will be at 6KHz. NOTE: when the MID control is set at
12:00 straight up the SWEEP will not have any affect on the signal since there is not
boost or cut being applied.
6. TREBLE CONTROL
The TREBLE control adjusts the boost or cut that is applied in the high frequency
portion of the spectrum of PREAMP1. The available TREBLE boost and cut range is
+/-15 decibels.
