350x • 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 balance 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 your speaker cabinet can handle the peak levels. Adjust the controls slowly, and use common
sense.
Midrange Controls
Your 350x comes equipped with two different controls for setting the amount of midrange present: one for
boosting and cutting 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, turning the Level control counter-clockwise cuts the desired tone. Turning the Level con-
trol 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 con-
trol. 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 use-
ful 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 sub-
sequent 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.
Effects Blend Control
The Effects Blend Control "blends" the signal sent from your instrument with the signal coming from your
EXTERNAL effects unit. (In other words, it has nothing to do with the SubWave™ effect onboard your
350x.) With the Effects Blend fully counter-clockwise ("DRY"), no signal from your external effects unit will
be heard. As you turn this control clockwise, more of the effect can be heard in the overall sound. When
the Effects Blend control is set fully clockwise ("WET"), no true or unaffected signal is heard other than
what your external effects unit provides. If your external effects unit has a similar control, adjust it to the
fully clockwise ("WET") position. This will avoid any possible phasing problems.
