BLACK BEAUTY – ACTIVE TONE CONTROL SECTION
BASS CONTROL
The Bass control employs a shelving-type circuit and boosts or cuts the bass response + /–15dB, from about 30Hz to 100Hz.
Starting at the control's mid-position ("center-click"), turning the control counter-clockwise cuts the bass response, and turning the
control clockwise boosts the bass response.
You'll find that the Bass Level control will boost or cut the SubWave™ effect along with the "clean" bass signal. That's because of the
range of frequencies covered by this particular control. You can use both the Bass and SubWave™ Level controls to get a good bal-
ance between how much bass you want in your clean sound, and how much of a bass boost you want when engaging the
SubWave™. Some users will want a significant boost, while others may be striving for a more consistent level (or "unity gain"). Again,
let your ears and musical taste be the judge.
Note: Setting both the Bass and SubWave™ Level controls near or at maximum boost will increase the overall amount of bass
in your signal VERY SIGNIFICANTLY! We're all in favor of that, just so long as the peak levels don't exceed the internal speaker's
excursion limit, which would be obvious to your ear. Adjust the controls slowly, and use common sense.
MIDRANGE CONTROLS
Your Black Beauty comes equipped with two different controls for setting the amount of midrange present: one for boosting and cut-
ting the level of midrange, and another for setting the specific midrange frequency that will be adjusted in level.
MIDRANGE LEVEL CONTROL
The Midrange Level control cuts or boosts the frequency set by the Midrange Frequency control. Starting at mid-position, turn-
ing the Level control counter-clockwise cuts the desired tone. Turning the Level control clockwise boosts the desired tone (set
by the Midrange Frequency control). When the level control is set at mid-position ("center-click"), turning the frequency control
will have no effect on the sound.
To find the midrange area you are looking for:
1. Adjust the Midrange Level control to the full boost or cut position.
2. Rotate the Midrange Frequency control until the desired area you wish to cut or boost is found.
3. Adjust the Midrange Level control to the desired amount of cut or boost.
MIDRANGE FREQUENCY CONTROL
The Midrange Frequency control sets the area that is to be cut or boosted by the Midrange Level control. If the Midrange Level
control is set at mid-position, turning the Frequency knob will have NO affect.
Some hints: If you need to "cut through" the band a little more, try boosting 200 to 400 Hz. If you like a more transparent or
"scooped" sound, try cutting at 800 Hz. The midrange controls are especially useful in controlling fretless basses and their
inherent qualities.
TREBLE CONTROL
The Treble control employs a shelving-type circuit and boosts or cuts the high frequencies (and their subsequent octaves) +/–15dB
from about 2kHz to 14kHz. Starting at mid-position, turning the control counter-clockwise cuts the treble response, while turning the
control clockwise boosts the treble response.
