Tone Controls - YORKVILLE BASSMASTER XS 800 Manuel De L'utilisateur

Drive Mix Control
The Drive Mix control becomes active when the
underlying clean tone below the overdriven tone. In the Dry, counter-clockwise setting, clean signal
is allowed to dominate the mix, with no overdrive. When rotated clockwise, into the Wet region, the
overdriven sound becomes more apparent. The
is the dominant sound in the mix (fully Wet position). This helps you achieve a perfect Wet/Dry blend,
between a completely clean and a completely saturated overdrive tone. This is a unique and handy
feature that allows unheard of levels of tonal control.

Tone Controls

The five overlapping controls cover the entire audio spectrum. Each tone control permits a wide range
of sonic adjustment. Each tone control has a variable boost and/or cut of 15 db. The center position
denotes a neutral or nominal setting.
Tip: It's a good idea, when starting out, to center all tone controls. While playing, adjust them until
you achieve the desired sound. Remember, if the Parametric Mid control is set at 0, rotating the
Frequency control will have no effect. The Bass control adjusts the level of the lowest note frequen-
cies, Low-Mid the next range up from that. The Parametric Mid allows more precise control for the
mid frequencies - more on this below). The Hi-Mid covers the highest notes and middle harmonics
and the Treble regulates the upper harmonic range.
Parametric Mid Control
The Parametric Mid control enables adjustments to be centered on frequencies ranging from
150 Hz – 15 kHz.
Tip: To use this control, set the position of the Parametric Mid level control to cut or boost. Rotate the
Frequency control until the desired frequency range is found. Once the frequency range is chosen,
adjust the Parametric Mid level until the desired cut or boost level is achieved.
Tip: Using the Parametric Mid in conjunction with the Scoop feature. When using the Parametric
Mid, it's possible to enhance the Scoop's capabilities by letting the two tone-shaping controls work
in tandem. If you like the added bottom of the Scoop but wish to soften the midrange at 1Kz (but still
maintain the higher frequencies); adjust the Parametric Mid Frequency control to 1.0Kz and then use
the Parametric Mid level control to cut as much as you need. The 400 Hz frequency has been conve-
niently marked on the Parametric Mid's Frequency control.
Scoop Control
The Scoop enhances the tone of the bass by shaping the mid frequencies around 400 Hz. By shap-
ing the bottom-end fundamentals, and high frequency brilliance, subtleties normally hidden are
revealed. The Scoop shapes specific upper and lower frequencies while notching particular mid
frequencies. It utilizes a variable tone curve that reacts differently depending on where it is set. The
result is a greatly expanded tonal range and control over that tone. Its fundamental use is like the
traditional Scoop control found on our other popular Yorkville Bassmaster amplifiers, but with greatly
expanded dimension and tonal control. As shown on the front panel, the center frequency of the
scoop is centered around 400 Hz. If you desire more scoop, turn the parametric mid frequency con-
trol to 400 and the gain counter-clockwise until the desired amount is reached
Tip: As with the tone controls, it's recommended to set the Scoop control initially at the mid point.
Adjust it slowly, either way, until the desired tone is achieved.
Tip: Combine the Scoop, the
TUBE
Drive and the Drive Mix to their maximums and play your bass while slowly rotating the Scoop
from its off position to its MAX position, you'll find the variation in the effect to be quite dramatic and
yet very musical at the same time.
Effects Return Blend Control
A dry, un-effected signal is sent out through the EFX Send jack to external effects units, it then can
return to the amplifier through the Effects Rtn jack. The Effects Rtn blend control regulates how
