CV UTILITIES

Legendary Analog Portamento 

Controller and CV Utilities for Eurorack

Controls 

(1) 

MIXER SIG IN 

– Connect incoming signals via 3.5 mm  

TS cables. Inputs 3 and 4 feed +10/-10 V respectively to 

the mixer inputs if no jack is inserted, which can be used 

to offset the overall mixer output control voltage.

(2) 

PORTA SIG OUT 

– Send the portamento signal to another 

module via 3.5 mm TS cable.

(3) 

PORTA SIG IN 

– Connect a signal to the portamento 

section via 3.5 mm TS cable.

(4) 

SIG LEVEL 

– Adjust the level of the signals connected to 

the mixer inputs.

(5) 

INV OUT 

– Send the mix of inputs 1-4 as an  

inverted signal.

(6) 

NON INV OUT 

– Send the mix of inputs 1-4 as a  

non-inverted signal.

(7) 

TIME 

– Adjust the portamento time.

(8) 

CV IN 

– Connect a voltage to control the portamento time 

from another module.

(9) 

+10/-10 V LEVEL 

– Adjust the level of the +10 V and  

-10 V outputs.

(10) 

+10/-10 V OUT 

– Send the +10 V and -10 V signals 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.
