SCRAT v1.1
by neutral labs
Manual
Hello, owner.
SCRAT is an aggressive sounding multimode Steiner-Parker filter with a
twist: You can change the resonance response by plugging in components
like diodes, capacitors or resistors directly to the front panel. A
set of preset cartridges is also available, which gives you instant
access to a variety of filter sounds.

- Page 2 Specifications ● Width: 9 HP ● Supply voltage: +12V/-12V (Eurorack 10-pin header) ● Current draw: ○ +12V: 35 mA ○ -12V: 35 mA ○ 5V: unused, 0 mA ● CV inputs: 2x 0V to 10V usable, -12V to 12V absolute Connecting SCRAT to Eurorack power Connect a 10 pin Eurorack power cable to the 2x5 power header on the back of the module.
- Page 3 Manual Controls Control Function This switches the filter mode from high-pass (top position) to low-pass (bottom position). This changes the type of resonance. In the top position, you will get a clean resonance curve while in the bottom position there will be added harmonics that heavily distort the sound –...

The range of this knob bottom right is limited, making it a control for fine adjustments. The knob) full range can only be accessed by adjusting both knobs, however, with this knob set to the 12 o’clock position, the...
- Page 5 Modifier Ports The ports on the top of the module labeled P|S|G|S|P support the plugging in of pre-assembled cartridges available from Neutral Labs, as well as individual passive components like resistors, capacitors or diodes. LEDs and LDRs (light-dependent resistors) can be used as well, even in combination.
- Page 6 Serial (S) This is used for putting two components in series, the combination of which will then be in parallel to the feedback circuit. Put the first of the two components from P to S and the other one from the other S to the other P. Both of the S ports on either row are interconnected (as visualized by the half circles on the front panel graphics), so a series connection will be made between the components.
