(1) AUDIO IN – Use this 3.5 mm jack to ro ute an audio
signal into t he module for conver sion to a V-Trig
(voltage trigger) signal. The audio signal passes through
the SENSITIVI TY control bef ore being convert ed, and the
nal, conver ted signal then ex its the module at th e V-TRIG
OUT parall el connection s immediately to the r ight of the
SENSITIVITY knob.
(2 ) SENSITIVIT Y – Use this knob to adju st the gain of the
audio sign al coming into the modu le through the AUDIO
IN jack. Rot ate the knob until yo u nd a setting tha t gives
you the best audio-to-voltag e conversion.
(3 ) V-TRIG OUT – Use the par allel jacks to rout e the converted
audio-t o-voltage V-Trig signal bac k out of the module via
cables w ith 3.5 mm TS connect ors.
(4 ) S-TRIG IN – Route S-Trig (sw itch trigger) cont rol signals
into the mod ule via cables wit h 3.5 mm TS connector s
for conversion to V-Trig (voltage trigger) signals.
The conver ted V-Trig signal c omes back out of the
module via t he parallel V-TRIG OUT jac ks immediately
to the right o f the S-TRIG IN jack.
(5 ) V-TRIG OUT – Use th ese parallel jack s to send the
converte d V-Trig signal bac k out of the module via c ables
with 3.5 mm TS co nnectors.
(6 ) V-TRIG IN A/ B – Use these rows of 3.5 mm ja cks to route
in multiple V-Trig (voltage trigger) signals for conversion
to an S-Trig (switch t rigger) signal that e xits the module
via the S-TRIG O UT jack assigned to th is section of the
module. The V-TRIG I N A row of inputs go st raight to
conversi on and output, whil e the V-TRIG IN B row of
inputs p ass through the SWI TCH-ON TIME contro l before
being comb ined with the conver ted A signal for na l
output t hrough the S-TRIG OUT jac k. When any valid
V-TRIG input ac tivates the S-TRIG ou tput, any other V-TRIG
input ac tivity will be i gnored until the r st V-TRIG cycle
has ended.
(7 ) SWITCH -ON TIME – Use this knob t o manually limit or
exten d the “ON” time durati on of V-Trig signals c oming in
through t he V-TRIG IN B row of in put jacks. The “ON ” time
can be var ied from 40 millis econds to a full 4 sec onds.
(8 ) S-TRIG OUT – This jac k routes the nal S-Trig sig nal from
the V-TRIG IN A/B ja cks back out of th e module via cables
with 3.5 mm TS co nnectors.
Power Connection
The 961 INTERFACE mo dule comes with the r equired power cab le
for conne cting to a standa rd Eurorack power su pply system.
Follow the se steps to connec t power to the module. I t is easier to
make these c onnections be fore the module ha s been mounted
into a rack c ase.
1. Turn the power su pply or rack case p ower o and
disconne ct the power cabl e.
2. Insert the 16- pin connector o n the power cable into t he
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. Insert the 10 -pin connecto r into the socket on th e back of
the modul e. The connector ha s a tab that will align wi th the
socket for correct orientation.
4. After both en ds of the power cable hav e been securely
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 attaching the screws.
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
adjustments to the positioning while you get them all aligned.
After th e nal position has b een establishe d, tighten the
screws d own.
