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

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

controlled by the slider fbck

. 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.
