SALUT
Thank you for purchasing this
Xaoc Devices product. Batumi is a
fully voltage controlled quadruple
digital LFO module with a slew of
interesting and user-customizable
features. Each oscillator can be
used independently or in one of 3
synchronized modes as described
in paragraphs 1 to 4. The total fre-
quency range spans from 28 hours
in voltage controlled
divide mode,
up to 500 Hz. Truly compact (only
10 hp), economically attractive
yet uncompromised, Batumi is
a perfect solution for portable
modular setups, but can empower
any system signicantly.

supposed to point the same on the
busboard as well as the unit. The
module has been secured against

it is always a good habit to pay
attention to this. Now, mount the
screws provided and switch your
system back on.
