Subdecay Prometheus PM2 User Manual

Subdecay Studios – Prometheus

PM2 – Resonant Filter-

Your Prometheus pedal was hand
made in Newberg, Oregon with high
quality components.
Thank you for purchasing The
Subdecay Prometheus.

What is The Prometheus?

The Prometheus is a voltage
controlled 12dB filter which can be
manipulated by playing dynamics or
an internally generated signal.

Controls­Intensity: Controls the resonance of

the filter.

HP/BP/LP: Controls the shape of
the filter. Highpass, Bandpass, and
Lowpass.

Freq: Controls the resting cutoff
frequency of the filter. In Envelope
up, and Step mode, lower
frequencies are to the left and
higher frequencies are to the right.
In Envelope down mode this control
works backwards.

: Controls how the cutoff

frequency is modulated. Envelope
up, Step, and Envelope down
respectively.
Depth: Controls how much the filter
cutoff frequency is modulated.

: Controls the shape of

the control voltage generator. This
control is for step mode only.

Step: Controls the timing of the
sample/hold function. (time
between voltage samples) This
control is for step mode only.

Rate: Controls the speed of the
control voltage generator LFO (Low
Frequency Oscillator)

Battery:

To change the battery you must first
remove the 4 rear screws and the
rear cover. The battery should be
placed next to the switch in the
battery compartment. The battery
should be able to slide in and out
with out any friction. If the battery
needs to be forced in to place, it
could damage the your pedal.

Battery Life

When using a battery always unplug
the instrument input to conserve
battery life. When a cable is
plugged in the pedal is always on
even when bypassed.
The Prometheus current draw
relatively low considering the size of
the circuit. As the battery drains the
range of the filter will become
smaller, and the higher intensity
settings may become distorted.

Settings-

Envelope Filter Tricks- In Envelope Up

mode, the Prometheus operates much
like many other filters you may have
used. In Envelop Down mode, the
filter sweeps in the opposite direction.
You can even set the resting frequency
above or below the audio range to
create a slow attack effect.

Step Filter Fun- The timing of the Step

and Rate controls overlaps. When
running the Rate past the 12:00 mark it
can oscillate much faster than the Step
timer. Some very interesting
sequences are possible. Also, with the
Step control all the way up, and the
Rate below the 12:00 mark a smooth
autofilter effect is possible. It can even
sound a bit like a tremolo or phaser
with the right filter settings.

Fake Synth madness- Try running your

favorite fuzz or overdrive before the
Prometheus. LP and BP modes work
best for this effect.
