The Brief – Dusk is a digitally controlled analog filter. At its heart is an analog 12dB/Octave low

pass filter based around an old school integrated circuit called an Operational Transconductance

Amplifier or OTA. The OTA runs off of split +/-9V rails for great audio quality and a deep filter

sound. The digital side brings a whole bunch of convenient and powerful features like controlling the

filter setting, tap tempo, MIDI, 6 LFOs, and a platform for all the best filter modes in one small pedal.

The Power – 9VDC, 150mA, centre negative 2.1mm plug. We recommend you use a quality,

isolated, filtered, and regulated supply and be careful with daisy chaining or you could have hum.

Email us if you need any power supply help! (There's no battery inside).

The Jacks – The Input and Output are located on the top panel and have arrow indicators showing in

and out. On the left side of the pedal there's a standard 5 Pin DIN jack for MIDI Input. On the right

side of the pedal there's a 1/4" jack for Expression/Control Voltage Input.

The Filter Knob – This knob controls the position of the filter in each Mode. In CUT Mode this is

your main frequency cutoff control. With the Filter knob all the way up the filter is fully open, with

the knob all the way down the filter is fully closed. In ENV Mode you can limit the range of the filter

sweep, turn the knob up or down to keep the filter movement in that range. In LFO Mode you use the

Filter knob to set the range of the filter sweep. Leave it at noon for maximum LFO depth, turn it up or

down to keep the LFO movement in that range.

The Resonance Knob – This controls how much of the output signal is fed back into the input of the

filter. Resonance adds an interesting tonal quality to the filter sweep, a sound that pairs well with

sweeping through the frequencies and just sounds cool and filtery. Too much resonance can lead to

feedback, a loud howling sound, or weird laser sounds, which may or may not suit your musical

vision. There's a little blue trimpot on Dusk's PCB that lets you dial in the maximum resonance just

right for your setup and tastes. (It's in the top right corner and says *RES ADJUST* around it).

The Volume Knob – Depending on how you use your filter, you might need to raise or lower your

volume to keep your signal at unity or however you like it.

The Left Pushbutton – Chooses between the 3 Filter Modes of Dusk. CUT is Manual Mode and this

mode puts you in charge of the filter sweep. You can control the filter with the Filter knob, an

expression pedal, a control voltage, or MIDI messages. ENV is Envelope Mode, putting the dynamics

of your playing in control of the filter setting. (There's a little blue trimpot on Dusk's PCB that you

use to adjust the envelope sensitivity to your specific instrument. It's on the left side, lower middle,

and says *ENVELOPE SENS* around it). LFO mode uses 6 unique sounding digital waveforms to
