BASS
This control adjusts the amount of boost or cut in the low frequency portion of the
spectrum of PREAMP. The available BASS boost and cut range is +/-15 decibels.
Note: the Bass control is flat when the control is centered at 12:00.
MID
RANGE BOOST/CUT CONTROL
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 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 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 PREAMP. The available TREBLE boost and cut range is
+/-15 decibels.
GAIN
CONTROL
The Gain control allows Gain adjustment from a few decibels to approximately 50db
