2. UNDERSTANDING THE PRODUCT
FRONT PANEL 2.1
N ote that there are no input or output controls. FilterFactory is set up to give you unity gain
when bypassed or when the Mix control is at 0%. This means that signals running through
it are not boosted or reduced in gain. If you are using a line level input (as opposed to a
turntable) set the output of your source so that FilterFactory’s Input Level LED doesn’t go Red all
that often. Try to keep your levels in the green which is the optimum level for FilterFactory.
" Buzz Buzz sets the amount of distortion. The more buzz, the more distortion you will have.
Buzz will take you from subtle, at the
farthest left, to heavy distortion at the
farthest right.
NOTE: Buzz will increase the level of
your output signal substantially as you
turn it up. Use the Trim control to get
the level back to where you want it
while the Buzz circuit is engaged.
" Trim: Sets the output level of the
Buzz circuit. This can be set anywhere
from inaudible to extremely loud. Use
with caution.
" Buzz Engage: Toggles the buzz
circuit in and out.
" Buzz Momentary: Temporaily
engages the buzz circuit. This is useful
for tapping patterns to create distortion
hits and rhythms.
Note: When an effect is engaged, the
Momentary will dis-engage it, when an
effect is not engaged the momentary
will engage it.
" StereoFilter: Frequency: Sets the
resonant frequency of the stereo filter.
Use it in conjunction with the
resonance control. The more resonance
you use the more distinct any changes
you make with frequency will be. The
frequency tuning range of the filter covers a 12 octave range from 10 Hz to 40 kHz. The External
CV input can control this and has been adjusted to provide standard 1 Volt/Octave response.
" Filter Type: This control selects the basic sound of the filter. Each filter type has a unique
sound. You will find situations where each one offers you a unique effect on a given signal.
The High Pass will roll off the bass of your signal. It will make things sound thinner. (See Fig. 1)
The Band Pass filter acts like Wah pedal and puts a peak in the middle of your signal. (See Fig. 2)
This is great for hilighting certain frequency ranges or for creating a sweeping sound with the
frequency knob.
The Notch Filter works the exact opposite of the Band Pass filter. It puts a notch in your signal,
essentially killing a small frequency band. This effect often sounds like talking through a pipe.
It will also create unique sweeping sounds, (that is similar to a phase shifter) when used in
conjunction with the frequency knob. For best Notch result put the Resonance knob fully
counter-clockwise.
