ACTIVE TONE CONTROL SECTION

BASS CONTROL

The Bass Control employs a shelving type circuit and boosts or cuts the bass response +/–15dB, from about 30 Hz to 100 Hz. Starting at mid-center click-position, turning the control counter clockwise cuts the bass response and turning the control clockwise boosts the bass response.

MID RANGE SECTION

LEVEL CONTROL

The Level control cuts or boosts the frequency set by the Frequency control. Starting at mid-posi- tion, turning the Level control counter clockwise cuts the desired tone. Turning the Level control clockwise boosts the desired tone (set by the Frequency control). When the level control is set at mid (center click) position, turning the frequency control will have no effect on the sound.

To find the midrange area you are looking for:

1.Adjust the LEVEL control to the full boost or cut position.

2.Rotate the Frequency control until the desired area you wish to cut or boost is found.

3.Adjust the Level control to the desired amount of cut or boost

FREQUENCY CONTROL

The Frequency control sets the area that is to be cut or boosted by the Level function. If the Level control is set at mid-position, turning the Frequency knob will have NO effect.

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 sound, try cutting at 800 Hz. The midrange area is 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 octaves +/–15dB from about 2kHz to 14kHz. Starting at mid-center click-position, turning the control counter clockwise cuts the treble response, while turning the control clockwise boosts the treble response.

EFFECTS BLEND

The Effects Blend Control “blends” the signal sent from your instrument with the signal coming from your effects unit. With the Effects Blend full counter clockwise (“dry”), no signal from your effects will be heard. As you turn this control clockwise, more of the effect can be heard in the overall sound. When the Blend knob is fully clockwise (“wet”), no true or unaffected signal is heard other than what your effects unit provides. If your effects unit has a similar control, adjust it to the full (wet) position. This will avoid any possible phasing problems.

The Blend circuit is similar to that used on recording consoles with the effects loop on a “side chain” to the normal circuit. Unless the control is set to the full wet position, you will always get the full sound of your instrument AND get the diversity an effects unit offers. This circuit is also effective in reducing noise generated by effects units because it is located after the gain stages in the preamp.
