(1) PW MOD IN – Accept s a voltage from ano ther module to
control the pulse width.
(2 ) VCO OUT – S end the VCO signal to one or t wo sources via
3.5 mm TS cabl es.
(3 ) WAVE FORM – Selec t pulse, triangle o r sawtooth
wavefor ms for the VCO.
(4 ) PULSE WIDTH – Adju sts the pulse wid th modulation
based on t he voltage receive d at the PW MOD IN jack.
(5 ) MOD MANUAL – Se ts the ratio bet ween the upper and
lower por tions of the pulse w ave.
(6 ) SY NC OUT – Sends a synchr onization signa l via 3.5 mm
TS cable.
(7 ) RANG E – Sets the pitch ran ge of the VCO in octave st eps.
(8 ) SY NC IN – Accepts a synchr onization signa l via 3.5 mm
TS cable.
(9 ) WEAK /STRONG – Determines t he accuracy
of synchronization.
(10) PITCH – Fine tunes the pitch.
(11) MOD LEVEL – Adjusts t he level of the signal co nnected
to the asso ciated MOD IN jack.
(12 ) MOD IN – Accepts vol tages that contro l or modulate
the VCO pitch.
Power Connection
The modul e comes with the req uired power cable f or connecting
to a standa rd Eurorack power su pply system. Fol low these
steps to con nect power to the mo dule. It is easier to make
these con nections bef ore the module has be en mounted into
a rack cas e.
1. Turn the power supp ly or rack case power o and
disconne ct the power cabl e.
2. Ins ert the 16-pin conn ector on the power c able into the
socket on t he power supply or rac k case. The connec tor has
a tab that wi ll align with the gap in t he socket, so it can not
be inser ted incorrec tly. If the power supply d oes not have
a keyed socke t, be sure to orient pi n 1 (-12 V) with the red
stripe o n the cable.
3. Ins ert the 10-pin co nnector into the s ocket on the back of
the modul e. The connector ha s a tab that will align wi th the
socket fo r correct ori entation.
4. Af ter both ends of the po wer cable have been se curely
attac hed, you may mount the mo dule in a case and tur n on
the power supply.

Installation
The neces sary screws ar e included with th e module for mount ing
in a Eurorac k case. Connect t he power cable bef ore mounting.
Dependi ng on the rack case, th ere may be a series of xed holes
spaced 2 HP ap art along the leng th of the case, or a tr ack that
allows indi vidual threaded p lates to slide along th e length
of the cas e. The free-movi ng threaded plate s allow precise
positio ning of the module, bu t each plate should be p ositioned in
the approx imate relation to th e mounting holes in yo ur module
before a ttaching the sc rews.
Hold the mo dule against the Eur orack rails so that e ach of the
mounting h oles are aligned wi th a threaded rail o r threaded
plate. Att ach the screws par t way to start, w hich will allow
small adjus tments to the pos itioning while you g et them all
aligned. After the nal position has been established, tighten the
screws d own.
