XAOC Devices Sarajewo
Analog BBD delay with three taps and tap tempo
10 HP Eurorack module
Sarajewo by Xaoc Devices is an analog delay module based on newly manufactured BBD (Bucket Brigade Delay) chips. It features three delay taps, an external clock input with tempo sync factors, tap tempo, and extensive CV control. Delivers warm, characterful analog delay with signal level indicators, adjustable feedback filter, and clean BBD sound quality.
Features
- Multi-mode analog VCF with simultaneous LP/BP/HP outputs
- Voltage-controlled resonance up to self-oscillation
- 1V/Oct tracking for use as a sine oscillator when self-oscillating
- FM input with attenuverter for audio-rate filter modulation
Controls & Jacks (18)
- Sync — Clock sync input for tempo-syncing the delay time.
- Tap Tempo — Tap tempo button with green LED. Press repeatedly to set delay time by tapping rhythm. The LED flashes at the current delay rate.
- Ext Feedback Loop — External feedback loop insert point for processing the feedback signal.
- Tone — Vertical TONE slider (TREB at top, BASS at bottom). Shapes the frequency content of the delayed signal — acts as a tilt EQ, rolling off treb
- Delay Time — Main delay time knob with calibrated ms markings (30-1500ms). The surrounding dial shows delay times and clock division ratios (1:6 through
- Level — Output level control (0-10 scale). Sets the overall volume of the delay output before the Mixed Output jack.
- Effect — Dry/Wet mix control. Fully CCW (DRY-0) passes only the input signal, fully CW (10-WET) passes only the delayed signal. Center position gives
- T2 — Tap 2 output jack — second multi-tap delay output.
- Input — Main audio input.
- Mix CV — CV input for voltage control of the dry/wet mix.
- Mixed Output — Main mixed audio output (dry + wet combined).
- FBCK — Feedback amount — controls how much of the delayed signal is fed back into the input. Higher settings create more repeats, self-oscillation
- Delay Range — Vertical slider setting the delay time range from MIN to MAX. Controls the overall delay range that the large Delay Time knob sweeps through
- T1 — Tap 1 output — first multi-tap delay output. Provides the earliest repeat in the delay pattern.
- T3 — Tap 3 / TAPS output — third multi-tap delay output. Labeled TAPS on panel, provides the longest delayed tap.
- Input Indication — Lights to indicate audio signal is present at the Input jack.
- BBD Off-Range — Lights red when the BBD clock frequency goes out of optimal range, indicating potential audio quality degradation.
- T3 Time — T3 TIME display — shows the delay time of the third tap relative to the master delay time.
