The Scrutator is a unique, full featured
Sample Rate and Bit Reducer pedal with
modulation control and includes the following
features:
• Expression or CV input for controlling and
modulating Bit, Rate, Filter, Q and any
combinations of these settings
• Pre Amp control for input gain/attenuation
• Bit Rate reduction control from approximately
16bit to 2bit
• Sample Rate reduction control from
approximately 48kHz to 300Hz
• Selectable 2 pole Bandpass or Lowpass Filter
• Q control for filter bandwidth and amplitude
amount
• Clip LED indicates input clipping and adjustable
with Pre Amp control
CONTROLS AND CONNECTIONS
1. 9VOLT DC POWER JACK - only for use with standard 2.5mm neg-tip 200mA
9volt DC power supply.
2. INPUT JACK - Connect instrument cable
3. EXPRESSION JACK INPUT - Connect expression pedal. BIT, RATE, FILTER,
and Q controls are all capable of being controlled by the EXP/CV input. You
can choose any combination of these pots for external control.
4. BIT – Bit rate reduction. Approximately 16bit to 2bit .
5. MIX - Dry/effect mix control.
6. Q - Sets the bandwidth and amplitude amount of the filter.
7. FILTER - Sets frequency of low pass/band pass 2 pole filter.
8. RATE - Sample rate reduction. Approximately 48kHz to 300Hz.
9. PREAMP - Input gain/attenuation. Adjust per clipping LED. Unity gain approx
12 o’clock.
10. CLIP LED - Indicates input clipping. Adjustable with PREAMP control.
11. MAIN LED - Effect on/off
12. OUTPUT - Connect to amplifier
13. STOMP SWITCH - Turns effect on or off. Also used to assign expression/cv
control and assign filter type selection.
EXPRESSION PEDAL AND CV
CONTROL
1. With the effect on, hold down the stomp switch.
2. While holding the stomp switch down, turn any (or a combination of all) of the
following controllable effect knobs: RATE, FILTER, Q and BIT. This will
activate assignment to expression or cv control. You must turn a selected
knob completely left to activate a clockwise sweep and completely right to
activate a counter-clockwise sweep.
3. Release the stomp and now the assignment has been made; this assignment
will stay that way until you change it, regardless of unplugging the power or
not. Your expression pedal or cv input will now adjust the selected controls.
4. You can define the range of effect assigned to the EXP/CV control by
changing the knob setting. FOR INSTANCE: Starting at 12 o’clock, setting
the knob counterclockwise (anticlockwise) to 7 o’clock will give you maximum
positive sweep for that effect. Or Setting the knob clockwise to 2 o’clock will
give you less overall negative sweep range for that effect.
5. A SETTING EXAMPLE: Hold down the stomp switch and turn the FILTER
knob from a 12 o'clock position counter-clockwise to the left. Release the
STOMP. Now your expression pedal will control the filter like a wah-wah
pedal, opening and closing the filter. Turning the knob setting toward 12
o'clock will now reduce the overall range of the EXP/CV sweep.
REMOVING AN EXPRESSION PEDAL AND
CV CONTROL ASSIGNMENT
1. Hold down the stomp.
2. With the stomp down, turn the knob with the assigned setting to 12 o’clock.
3. Release the stomp. Now that parameter is no longer assigned to the EXP/CV
control and it is in manual mode.
NOTE: Unplugging the EXP/CV input will put the pedal in manual mode, but
the assignments stay until you zero them out.
CHANGING FILTER MODES
The Scrutator includes both Low pass and Band pass filter modes. The
default shipping mode is Low pass. In order to switch between these two
modes:
1. Unplug the power supply.
2. Hold the stomp switch down and plug the power supply back in (keep holding
the stomp until the pedal is powered up).
3. Now the pedal is the other filter mode.
Making this filter selection does not affect the EXP/CV assignments, and once
the filter has been selected, it will remain that way until you change it,
regardless of unplugging the power or not.
NOTE: The easiest way to determine filter mode is to set the FILTER pot all
the way clockwise and listen to the selections. Low pass will allow all
frequencies through and band pass will be very thin sounding, because you
are filtering out all the frequencies below that highest setting.
BASIC OPERATION AND SAFETY
1. Connect to an industry standard 9 Volt DC power supply!Incorrect
voltage and AC power supplies will damage your pedal and void the
manufacturer’s warranty! We also recommend using our Malekko 9
Volt Wall Wart, available through our website.
2. Do not use this apparatus near water.
3. Clean only with dry cloth.
4. Do not block any ventilation openings. Install in accordance with the
manufacturer’s instructions.
5. Do not install near any heat sources such as radiators, heat
registers, stoves, or other apparatus (including amplifiers) that
produce heat.
6. Protect the power cord from being walked on or pinched particularly
at plugs, convenience receptacles, and the point where they exit from
the apparatus.
7. Unplug this apparatus during lightning storms or when unused for
long periods of time.
8. No user serviceable parts inside. Refer all servicing to qualified
service personnel. Servicing is required when the apparatus has
been damaged in any way, such as power-supply cord or plug is
damaged, liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does
not operate normally, or has been dropped.
9. WARNING:To reduce the risk of fire or electric shock, do not expose
this apparatus to rain or moisture.
