EXT SIG X/NOISE jack routes audio signals or noise into the
(1)
ring modulator. The audio signal or noise coming in through
the EXT SIG X/NOISE jack is combined with and modulated
by the carrier signal routed into the EXT SIG Y/LFO jack.
EXT SIG Y/LFO jack routes the carrier signal into the
(2)
ring modulator. The carrier signal can be in the audio
range, such as a 500 Hz sine wave, or a signal from
Low Frequency Oscillator (LFO).
R.M OUT jack sends out the final ring modulator signal.

PINK output jacks offer dual white pink noise outputs for
(4)
use other modules.
WHITE output jacks offer dual white noise outputs for use
(5)
with other modules.
EXT SIG input jack routes external signals into the S&H
(6)
circuit for processing. Use the EXT/LFO/NOISE switch to
optimize the EXT SIG input for different types of signals.

EXT/LFO/NOISE sliding switch optimizes the EXT SIG for use
(7)
with control signals (EXT), signals from a Low Frequency
Oscillator (LFO) or noise signals (NOISE).
CLOCK OUT jack sends out a clock signal generated inside
(8)
the S&H circuit.
CLOCK RATE slider controls the internal clock signal's rate
(9)
before the clock signal is routed out through the CLOCK
OUT jack.
S&H OUT jack sends out the final S&H (Sample & Hold)
(10)
signal over cables with 3.5 mm TS connectors.
LAG TIME slider can be used to smooth out the changes
(11)
between control voltage values as the slider is raised, similar
to a portamento or glide effect on a keyboard.
EXT CLOCK IN input jack routes an external clock signal into
(12)
the S&H circuit.
WAVEFORM knob selects between sine, triangle, square,
(13)
ramp and sawtooth waveforms for the LFO.
FREQ RANGE sliding switch selects between high (H),
(14)
mid (M) and low (L) frequency ranges.
TRIGGER jack allows a control voltage to trigger the LFO
(15)
waveform by resetting the amplitude to 0. The waveform
then returns to the original amplitude at a rate set by the
DELAY slider.
FREQ slider fine-adjusts the LFO frequency within the range
(16)
chosen by the FREQ RANGE switch.
DELAY slider controls the amount of time that elapses
(17)
between the beginning of a new note and the LFO's
amplitude peak.
FREQ CV IN input jack allows a control voltage to control the
(18)
LFO frequency in place of the FREQ slider.
OUTPUT LEVEL sliding switch selects between a
(19)
full-strength LFO output signal (x1 setting) and a
1/10th-strength signal (x 1/10 setting).
LFO OUT output jacks offer dual LFO outputs for use with
(20)
cables with 3.5 mm TS connectors.
