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,

The module requires 12hp worth of free space
in the Eurorack cabinet. The ribbon-type pow-
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 may
cause serious damage to other components
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.
Sarajewo features an audio delay line consist-
ing of three BBD chips of 4096 stages each (see

the outputs ensure optimal conditions for the
BBD chips to process the signal.
In general, the incoming signal must be band–
limited in order to prevent high frequency com-
ponents from interfering with the clock. Simi-

2. The signal you wish to process should be
patched to the input jack . The level knob
above controls the amplitude with the in-
put indication multicolor LED providing
visual feedback. The outputs from individual
taps are labeled t1, t2, and t3, respectively:
,
,
. The central large t3 time dial
allows for precise setting of the overall delay
time of the three stages, from about 20ms to
over 1.5s. The delay time can be modulated
via CV patched into the corresponding jack
below or synchronized to an external clock
source via the input sync
. Since all three
BBD chips share a common clock, using the t
1
and t2 outputs will provide signals delayed by
1/3 and 2/3 of the t3 time, respectively. The
mixed output delivers a continuous mix of
your input signal and the t3 tap. The balance is
controlled both by the effect knob and the
CV patched into the jack mix cv
. The sig-
nal from the input ext feedback loop is
mixed with the input of the delay line. This jack
is normalized to the t3 output, however, the
connection can be broken by sending one of the
tap outputs to an external processor (such as

. The bbd off-
range led indicates that the delay time set
by the combination of the t
3 time dial and the
incoming CV signal exceeds the time range of
the module. When the CV inputs are in use, the
corresponding knobs act as offsets.
Sarajewo is AC coupled and accepts modular
level audio signals (10Vpp and higher). The
level knob attenuates the input to prevent
distortion (indicated by the color of the input
indication LED). When it turns from green
to yellow and then to red, it means the signal
is too hot and the BBD chips may introduce
audible distortion.
