Thank you for purchasing this Xaoc Devices
product. Jena is a digital module that
and audio signals, a wavetable oscillator, a
Walsh function generator, or a rhythm genera-
tor. Jena is a new member of the Leibniz Binary
Subsystem which operates on signals and volt-
ages by manipulating binary 8-bit numbers.
The Leibniz subsystem offers direct access to
all individual bits of data which can be mixed
and cross-patched (like in the popular circuit
bending experimental technique, but without
the risk of damaging your device). Please note
that for analog inputs and outputs it needs to
be paired with other Leibniz modules, such as
Drezno. Complex chains will be possible as more
components are added to the system. For ex-
ample, you can use two Lipsk expanders (one
before Jena, and another one after Jena in the
chain) for unlimited patching.
The module requires 8hp worth of free space
in the eurorack cabinet. Always turn the pow-
er off before plugging the module into the bus
board using the supplied ribbon cable. Pay
close attention to power cable pinout and ori-
entation. The red stripe indicates the negative
rail and should match the dot or –12V mark on
the bus board as well as the unit. Jena is inter-
nally secured against reversed power connec-
tion, however rotating the 16-pin header may
cause serious damage to other components
of your system, because it will short circuit the
+12V and +5V power lines. Always pay partic-
ularly close attention to the proper orientation
of your ribbon cable on both sides! Besides the
power cable, you will also need to connect Jena
to other components of your Leibniz Subsys-
tem. For this purpose, Jena comes equipped
with a single 10/10-pin ribbon cable, and
there should also be at least one such cable
included with your other Leibniz module(s).
The general logic is simple: connect inputs to
outputs. For example, you can use one ribbon
to join the out header of your Drezno to the
in header of Jena, and another to connect the
out in header of Jena to the header in Drezno.
This will make the data from the ADC section
in Drezno pass through Jena before returning
to the DAC section in Drezno.
It is a good idea to have all your Leibniz mod-
ules connected before mounting them in the
data processing principle of jena
