Thank you for purchasing Dual Multi Kit.
Dual Multi is a dual buffered multiples.
Buffered multiples have advantages over passive multiples. Since passive multiples
split the signal, in case of voltage-critical signal such as V/Oct to VCO, the pitch will
vary from one output to the other.With buffered multiples each output will be a perfect
copy of the input.
Because buffered mults isolate their outputs from the input, any faults or shorts
present at the input will not pass through to a connected module.

Place the jack connectors
Install the jack connectors.
Before placing the jacks make sure that
none of the legs of the sockets are bent
then place the them.
don't solder them yet.
Place the faceplate
Place the faceplate. To make sure of the
orientation with the PCB, look at the
power connector. The black line below the
connector indicates not only -12V but
also the bottom of the PCB. Once the
faceplate placed screw the nuts on the
jack connectors.
Solder the jack connectors
turn the PCB over and solder the jack
connectors. Make sure the connectors are
flush against the PCB before soldering
them.
Once all the components are soldered,
check the PCB to avoid any unsoldered
pads, solder-bridges etc.
Check your module
Set your multimeter to "continuity",
connect one of the probe to one the the
ground pin. Test +12V and -12V pins with
the other probe.
your multimeter should not ring, if it rings
there is a short.
