Quick Start Guide

903A RANDOM

SIGNAL GENERATOR

Legendary Analog Noise Generator

Module for Eurorack

Outputs

Send a pair of white and/or pink noise signals to other modules via

3.5 mm TS cable.

Power Connection

The 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 off 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.

(3)

Insert the 10-pin connector into the socket on the back of

the module. The connector has a tab that will align with

the socket for correct orientation.

(4)

After both ends of the power cable have been securely

attached, you may mount the module in a case and turn

on the power supply.

Installation

The necessary screws are included with the module for mounting

in a Eurorack case. Connect the power cable before mounting.

Depending on the rack case, there may be a series of fixed holes

spaced 2 HP apart along the length of the case, or a track that

allows individual threaded plates to slide along the length

of the case. The free-moving threaded plates allow precise

positioning of the module, but each plate should be positioned in

the approximate relation to the mounting holes in your module

before attaching the screws.

Hold the module against the Eurorack rails so that each of the

mounting holes are aligned with a threaded rail or threaded plate.

Attach the screws part way to start, which will allow small

adjustments to the positioning while you get them all aligned.

After the final position has been established, tighten the

screws down.
