Noise Oscillator Build Document. V.5d - 9v - English
The Noise! Synthesizer is a CMOS IC based instrument.
The synth has 4 squarewave oscillators that modulate each other and go throught a clock divider.
After that, the separate divider outputs are mixed and shaped together.
Then the signal is routed through a pseudo ringmod.
Start with the Resistors:
The one
10R
resistor has the color code: 'brown-black-black'.
It is used at the power input as a fuse.
Bend the legs of the resistor 90 degrees and place the
10R
resistor at the
R1
location on the PCB.
Solder the resistor and cut off the legs with a sidecutter.
The three
1K
resistors have the color code: 'brown-black-red'.
These parts act as output protectors.
Place the resistors at
R2, R3
and
R4
Solder and cut the legs.
R5 to R8
are four 1M resistors.
R9
can be skipped, It is a voltage divider with R3, to reduce the volume of OUT2
Starve a modification option.
Look at the end of this document for more info!
Connect the two holes of
Starve
together to bypass this option.
Use a snipped-off leg of a resistor. Bend the leg in a U shape and solder.
If you skip this step, the module will receive no power!!
Diodes:
There are four zener diodes. These make sure that the CV input voltage cannot be higher than 9.1 volt.
