Installation:

The Make Noise DPO is an electronic signal generator requiring 70mA of +/-12V of regulated power and

properly formatted distribution receptacle to operate. It is designed to be used within the euro format

modular synthesizer system.

for the details of this format.

To install, find 28HP of space in your euro-rack synthesizer system, confirm proper installation of included

power cable on backside of module (see picture below), plug the 16 pin end power cable into the euro-rack

style power distribution board, minding the polarity so that the RED stripe on the cable is oriented to the

NEGATIVE 12 volt supply line. This is USUALLY at the bottom.

Please refer to your case manufacturers’ specifications for location of the negative supply.

Proper installation of included power cable on module.

Please note the RED BAND.
