150 RING MOD/NOISE/S&H/LFO

Legendary Analog Ring Modulator/

Noise/S&H/LFO Module for Eurorack

Controls

(1) EXT SIG X/NOISE jack routes audio signals or noise into the

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.

(2) EXT SIG Y/LFO jack routes the carrier signal into the

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).

(3) R.M OUT jack sends out the  nal ring modulator signal.

(4) PINK output jacks o er dual white pink noise outputs for

use other modules.

(5) WHITE output jacks o er dual white noise outputs for use

with other modules.

(6) EXT SIG input jack routes external signals into the S&H

circuit for processing. Use the EXT/LFO/NOISE switch to

optimize the EXT SIG input for di erent types of signals.

(7) EXT/LFO/NOISE sliding switch optimizes the EXT SIG for use

with control signals (EXT), signals from a Low Frequency

Oscillator (LFO) or noise signals (NOISE).

(8) CLOCK OUT jack sends out a clock signal generated inside

the S&H circuit.

(9) CLOCK RATE slider controls the internal clock signal’s rate

before the clock signal is routed out through the CLOCK

OUT jack.

(10) S&H OUT jack sends out the  nal S&H (Sample & Hold)

signal over cables with 3.5 mm TS connectors.

(11) LAG TIME slider can be used to smooth out the changes

between control voltage values as the slider is raised,

similar to a portamento or glide e ect on a keyboard.

(12) EXT CLOCK IN input jack routes an external clock signal into

the S&H circuit.

(13) WAVEFORM knob selects between sine, triangle, square,

ramp and sawtooth waveforms for the LFO.

(14) FREQ RANGE sliding switch selects between high (H),

mid (M) and low (L) frequency ranges.

(15) TRIGGER jack allows a control voltage to trigger the LFO

waveform by resetting the amplitude to 0. The waveform

then returns to the original amplitude at a rate set by the

DELAY slider.

(16) FREQ slider  ne-adjusts the LFO frequency within the range

chosen by the FREQ RANGE switch.

(17) DELAY slider controls the amount of time that elapses

between the beginning of a new note and the LFO’s

amplitude peak.

(18) FREQ CV IN input jack allows a control voltage to control

the LFO frequency in place of the FREQ slider.

(19) OUTPUT LEVEL sliding switch selects between a

full-strength LFO output signal (x1 setting) and a

1/10th-strength signal (x 1/10 setting).

(20) LFO OUT output jacks o er dual LFO outputs for use with

cables with 3.5 mm TS connectors.

Power Connection

The 150 RING MOD/NOISE/S&H/LFO module comes with the

required power cable for connecting to a standard Eurorack power

supply system. Follow these steps to connect power to the module.

It is easier to make these connections before the module has been

mounted into a rack case.

1. Turn the power supply or rack case power o and disconnect

the power cable.

2. Insert the 16-pin connector on the power cable into the

socket on the power supply or rack case. The connector has

a tab that will align with the gap in the socket, so it cannot

be inserted incorrectly. If the power supply does not have

a keyed socket, be sure to orient pin 1 (-12 V) with the red

stripe on the cable.
