FRONT PANEL CONTROLS 

1.

 

IN 1

,

 IN 2 JACKS:

 stereo audio inputs, 

INPUT 1

 (typically left) – is 

normalled

, i.e. pre-routed 

 to 

INPUT 2

 (right) when no audio cable is present 

on 

INPUT 2

. Typical input audio level: eurorack m/-5V with maximum 

up to +/-9V when saturation starts with higher audio amplitude.

 

2.

 

PRE-VCA CV INPUT JACK:

 

external 0…+5V CV input that controls 

the amplitude of the incoming stereo signal. Normalled to +5V when no patch 
cable is inserted.

 

3.

 

TONE

/GAIN*

 KNOB:

 

multi-function knob. By default it acts as a 

6db/oct 

TILT EQ

 for low and high frequencies (CCW and CW respectively) 

with no effect when the knob is at 12 o’clock. Secondary function is a gain 
boost for incoming audio, activated by turning while holding the 

ROUTING

 

button. Fully CCW the signal is at its original level - turn CW to boost.

 

4.

 

DISTORTION KNOB:

 

manual control over the distortion level. Is 

summed with an external CV applied to the 

DIST. CV

 jack.

 

5.

 

DISTORTION CV JACK:

 

external 0…+5V control over the distortion 

level.

 

6.

 

CLIP LED:

 

lights up when clipping occurs at the distortion stage.

 

7.

 

FREQUENCY KNOB:

 

manual control over the 

FILTER CUTOFF

.

 

8.

 

VCF CV INPUT JACK:

 

-5V…+5V CV input for the 

FILTER CUTOFF

The polarizer CUTOFF CV knob defines its amount, mixed with the setting of 
the 

FREQUENCY

 knob.

 

9.

 

CUTOFF CV KNOB:

 

polarizer / attenuverter for incoming CV to the 

FILTER CUTOFF.

 

10.

 

DELAY DRY/WET CV JACK:

 

0…+5V external CV input for 

the 

DRY/WET

 mix of the delay effect. Normalled to +5V when no patch cable 

inserted.

 

11.

 

DELAY KNOB:

 

manual control of the 

DRY/WET MIX OF THE 

DELAY

 effect, acts as attenuator for 

DRY/WET CV jack

.

 

12.

 

REPEATS

/TONE* 

KNOB:

 

manual control over 

REPEATS 

or

 

FEEDBACK 

level of the delay. Turn it fully CW for self-oscillation. Secondary 

/TONE*

 function (holding 

ROUTING 

while turning

 REPEATS

/TONE*

) adjusts 

the LOW-PASS FILTER after the WET output of the delay chain. Is summed 
with an external CV applied to the 

REPEATS CV

 jack.

 

13.

 

REPEATS CV JACK:

 

0…+5V external CV input for the 

feedback control of the delay effect.
