SAlut
Thank you for purchasing this Xaoc Devices
product. Sarajewo is an analog delay mod-
ule based on old school (but newly manufac-
tured) BBD (Bucket Brigade Delay) chips. It
features three delay taps, an external clock
input with various tempo sync factors, and a
wide range of settings controllable via CV. It is
based on high quality components with max-
imum effort put towards the highest sound
quality possible, while still preserving the
charm of the BBD technology. The module of-
fers a clean and warm analog sound with tons
of character and a comfortable user interface
with a tap tempo button, signal level indica-
tors, sync and CV inputs, four signal outputs,
and an adjustable feedback filter.

er cable must be plugged into the bus board,
paying close attention to polarity orientation.
The red stripe indicates the negative –12v rail
and should point in the same direction on both
the bus board and the unit. The module itself
is secured against reversed power connection,
however, reversing the 16-pin header
cause serious damage
of your system because it will short-circuit 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.
