Installation - Xaoc Devices BATUMI Operator's Manual

module
explained
sAlUT
Thank you for purchasing this Xaoc Devices prod-
uct. Batumi is a fully voltage-controlled quadru-
ple digital low frequency oscillator module with
lots of interesting user-customizable features.
Each LFO channel can be used independently or
in one of three synchronized modes (fig. 3). The
total frequency range spans from 28 hours (in
voltage controlled divide mode) up to 500Hz.

InsTAllATIOn

The module requires 10hp worth of free space
in the eurorack cabinet. The ribbon type power
cable must be plugged into the bus board, paying
close attention to polarity orientation. The red
stripe indicates the negative 12V rail and should
align with the dot, –12V or red stripe marks
on both the unit and the bus board. The module
itself is secured against reversed power connec-
tion, however reversing the 16-pin header
cause serious damage
your system by short-circuiting the +12V and +5V
power rails. The module should be fastened by
mounting the supplied screws before powering
up. To better understand the device, we strongly
advise the user to read through the entire manual
before using the module.

Batumi features four identical LFO channels
(fig. 1). Each channel's slider pot
one of the four main parameters as determined
by the global mode setting. In free mode, each
slider determines its own channel's frequen-
cy (from 0.01Hz to 100Hz). In the other three
modes, slider 1 acts as a master to the remain-
may
to other components of
1 controls
ing channels' frequency, allowing the remaining
sliders to perform other actions. For example, in
phase mode, sliders 2–4 define the phase shift,
in quad mode, sliders 2–4 define the amplitude,
and in divide mode, sliders 2–4 define the di-
vision of the master frequency. Frequency can
also be set with increased precision by entering
zoom mode, described later in this manual.
The frq/ph/div input
sponding slider parameter to be voltage con-
trolled (1V/oct). Doing so allows for an extended
frequency range from 500Hz all the way down
to 53 minutes! Expected voltage is –5V to +5V.
Above 100Hz, the waveforms tend to lose some
precision and amplitude.
The reset/sync input
trigger input that can serve as either cycle re-
set or external tempo sync depending on the
jumper settings described later in this manual.
The sine output
(–5V to +5V). In quad and phase modes, the
sines are shifted in relation to one another. The
saw/asgn output
upwards saw (ramp) waveform (–5V to +5V) or
one of the user-selectable shapes described later
in this manual. The square output
a square waveform (–5V to +5V).
The LFO sync mode toggle section
four oscillators to run free or sync to the master,
as follows:

To enter this mode, click the central button
until the red, free LED lights up. Now, all four
LFO channels work independently.
