Setting up your Listen Four Quarters 

1. Power off your Eurorack system. 

2. Connect the free end of the included power cable to a 16-pin Eurorack power header 

on your power supply distribution system. The red stripe should match the white line 

or -12V marking on the power distribution board. The other end of the power cable is 

a 10-pin connector which should already be connected to the 

Listen Four

 

Quarters 

with the red stripe on the power cable orientated towards the bottom of the module. 

Note: The 

Listen Four 

Quarters

 is reverse-polarity protected, but incorrectly 

connecting any module can damage any other on the power bus. 

3. Using the included screws, securely attach the 

Listen Four 

Quarters

 to the rails of 

your case.  

4. Power on your Eurorack system.
