A-188-2 BBD
Tapped BBD delay module using the MN3011 chip, providing six tapped outputs at BBD stages 396, 662, 1194, 1726, 2790, and 3328. Features two independent mixing sub-units, each with per-tap level/polarity controls and a wet/dry mix control, a voltage-controlled feedback section with polarizer, a built-in high-speed VCO clock, and CV control over delay time.1019
Capabilities 2
- Analog Delayanalog-delay
- Analog bucket-brigade delay with tapped outputs; delay time controlled by internal HSVCO with manual and CV control.1019
- Delaydelay
- Uses the MN3011 tapped BBD chip with six tap outputs, two mixing sub-units, voltage-controlled feedback, and a built-in high-speed VCO clock for delay time control.1019
Jacks 15 (5 in / 10 out)
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (5) | |||
| CV1 | cv | — | Control voltage input for BBD clock/delay time with approximately 1V/oct sensitivity.1019 |
| CV2 | cv | — | Second CV input for delay time, with attenuverter/polarizer potentiometer featuring center detent.1019 |
| Clock IN | clock | — | External clock input normalled from the clock output; accepts clock from another BBD module or external source for synchronized operation.1019 |
| Feedback IN | audio | — | Feedback input normalled to Tap 396 output; patch to any single tap output to select a different feedback source, or process externally before returning.1019 |
| Signal IN | audio | — | 1019 |
| Outputs (10) | |||
| CV OUT | cv | — | Outputs the summed control voltage from the manual delay knob, CV1, and CV2; useful for driving an external clock suppression filter.1019 |
| Clock OUT | clock | — | HSVCO clock output, normalled to the clock input socket; used to link multiple BBD modules to run on the same clock.1019 |
| Output 1 | audio | — | Mixed wet/dry output from mixer sub-unit 1; can be used as left channel of stereo pair or for other applications including feedback.1019 |
| Output 2 | audio | — | Mixed wet/dry output from mixer sub-unit 2; can be used as right channel of stereo pair or for other applications including feedback.1019 |
| Tap 1194 | audio | — | 1019 |
| Tap 1726 | audio | — | 1019 |
| Tap 2790 | audio | — | 1019 |
| Tap 3328 | audio | — | 1019 |
| Tap 396 | audio | — | 1019 |
| Tap 662 | audio | — | 1019 |
Parameters 5
| Name | Type | Range | Behavior |
|---|---|---|---|
| CV2 Polarizer | knob | — | Attenuverter for CV2 input with center detent indicating neutral (zero) position; left of center inverts the CV, right of center passes it normally.1019 |
| Delay | knob | — | Manually sets the BBD clock frequency, and consequently the delay time; combined with CV1 and CV2 inputs.1019 |
| Feedback | knob | — | Polarizer/attenuverter controlling feedback amount and polarity; center is neutral, left of center gives negative feedback (subtraction), right of center gives positive feedback (addition). Features center-detent potentiometer.1019 |
| Mix 1 | knob | — | Wet/dry blend for Output 1, ranging from pure dry (original input) to fully wet (BBD mix).1019 |
| Mix 2 | knob | — | Wet/dry blend for Output 2, ranging from pure dry (original input) to fully wet (BBD mix).1019 |
