GAIN CONTROL
The Gain control adjusts the volume of the preamp section. After the tone controls, Aural Enhancer, etc., have been adjusted to
your liking, the Gain control should be set to where the Preamp Clip LED barely flashes upon striking your loudest note; then
adjust the Master Volume control to the desired volume level. Since the Gain control is similar to a "Pad," a small amount of sig-
nal will be heard when the Gain control is rotated fully counter-clockwise. Utilizing these controls in this manner assures the
user of maximum signal-to-noise ratio without distortion caused by the preamp circuits clipping.
AURAL ENHANCER
SWR's Aural Enhancer was developed to bring out the fundamental low notes of the bass guitar, reduce certain frequencies
that help mask the fundamentals, and enhance the high end transients. The resulting frequency response should be similar to
that used for recording the bass in the studio. This effect becomes more radical as the control is turned to maximum. The
result is a more "transparent" sound and is especially noticeable when using the thumb style technique ("slapping") on the bass
guitar.
The Aural Enhancer can basically be described as a tone-shaping control, as it is a passive R/C network that alters the frequen-
cy response throughout the bass spectrum. This pre-shaping is "blended" into the original signal via the Aural Enhancer con-
trol. Exact frequencies affected are dependent on the characteristics of the instrument used.
BASS CONTROL
The Bass control employs a shelving-type circuit and boosts or cuts the bass response ±15dB. Starting at mid-position ("cen-
ter click"), turning the control counter-clockwise cuts the bass response; turning the control clockwise boosts the bass
response.
PULL TURBO FUNCTION
Pulling the Bass control to the "out" position widens the bandwidth of the Bass Control to include frequencies down to 30Hz
(low "B" on a 5-string bass). Since some of these notes can be felt more than heard, it is especially important to keep an eye
on the preamp and power amp clip LEDs. Constant clipping of these frequencies can diminish the life of Super Redhead's inter-
nal speakers or cause them to fail.
MID RANGE SECTION
LEVEL CONTROL
The Level control cuts or boosts the frequency set by the Frequency control a maximum of ±15dB. Starting at mid-position
("center click"), turning the Level control counter-clockwise cuts the frequency set by the Frequency control; turning the Level
control clockwise boosts the frequency. When the Level control is set at mid-position, turning the Frequency control will have
no affect on the sound.
To find the midrange area you are looking for:
1. Set the Level control to the full boost or cut position.
2. Rotate the Frequency control until the area you wish to boost or cut is found.
3. Adjust the Level control to the amount of cut or boost desired.
FREQUENCY CONTROL
The Frequency control sets the area that is to be cut or boosted by the Level control. If the Level control is set at mid-position,
turning the Frequency control will have no affect.
TIPS FOR USING THE MID RANGE CONTROLS
If you need to "cut through" the band a little more, try boosting 200 to 400Hz. If you like a more transparent sound, try cutting
800Hz. The Midrange controls are especially useful in controlling fretless basses and their inherent qualities.
