(1) SIG IN input jac ks accept audio sig nals over cables wi th
3.5 mm TS conne ctors.
(2 ) SIG IN k nobs control the ga in level at the SIG IN input s.
(3 ) VCA O UT (HIGH/LOW) output s connect to the i nputs
of exte rnal equipment over c ables with 3.5 mm TR S
connec tors. (Note that the se connection s are both
mono and not l eft/right). The HIG H mono output can b e
connec ted to the line-lev el inputs of mixer s, keyboard
amplier s or powered speake rs. The LOW output is an
instru ment-level signal tha t can be connecte d to the HI-Z
inputs o f equipment such as g uitar amplier s or mixers.
(4 ) LINEAR /EXPONENTIAL switc h toggles betwe en linear
and exponential output modes.
(5 ) INITIAL GAIN k nob controls the gai n level at the VCA
OUT jacks.
(6 ) MOD IN k nobs control the am ount of carrier si gnal
allowed thr ough from the MOD IN j acks.
(7 ) MOD IN jack s accept carrier signals from other modules
(e.g., a sine wave at 500 Hz) t o shape the volume
envelope s and waveforms of the SI G IN signals. For thes e
jacks, u se cables with 3.5 mm T S connectors.
Power Connection
The 130 DUAL VCA comes w ith the require d power cable for
connec ting to a standard Eu rorack power supp ly system.
Follow the se steps to connec t power to the module. It i s easier to
make these c onnections be fore the module has b een 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 module. T he connector has a t ab 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 x ed holes
spaced 2 HP ap art along the leng th of the case, or a tra ck 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 po sitioned 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 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.
