SARAJEWO syncable analog delay line operator’s manual rev. 1984/1.
module explained 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.
delayed signal is available after each chip. A high signal–to–noise ratio is achieved thanks to signal companding (dynamic compression at the input matched with dynamic expansion on each of the outputs). An anti-aliasing filter at the input and anti-imaging filters on each of the outputs ensure optimal conditions for the BBD chips to process the signal. via CV patched into the corresponding jack below 8 or synchronized to an external clock source via the sync input 9 .

10 CONTINUOUS AND TAP-TEMPO DELAY CONTROL 5 0 Sarajewo can operate as a continuously variable delay or in one of two synced modes in which the delay follows a given time base. The illuminated tap tempo button 17 always blinks with a period equal to the current delay time, while its color indicates the current mode.
ble is patched and new impulses arrive. When you unplug the cable, the module returns to the free mode, with the delay time reflecting the current position of the t3 time knob. feedback signal by blinking green and turning to red to warn that the signal is too hot and close to the clipping level of the BBD chip. Besides the depth of feedback, you can also shape the frequency content of your signal by adjusting the tone slider (fig. 3).
BBD TECHNOLOGY Bucket Brigade Delay is an analog technology used in vintage integrated circuits that were popular in the 1970s, long before digital signal converters and digital memory were affordable. Each BBD chip contains thousands of small capacitors and pMOS or nMOS transistors that act as analog switches. The signal is transferred as an electric charge that is passed from one stage to the next, like a fire brigade passing buckets of water (hence the name).
