Premium analogue delay from Erica's flagship Black Series range. Two bucket brigade device delay lines work simultaneously with smooth crossfading and tons of voltage control. Lovely. Supplier's Notes: Erica Black Series include high-end, unique functionality and superior quality modules. Only the best, highest quality components are used, all inputs and outputs are protected against undesired overvoltage. When designing Black Series, put design and usability superior. Big knobs are assigned to functions that make difference in sound. Erica Black series consist of range of modules that are needed to put together entire synth. Enjoy! The Erica Synths Black BBD is one of kind analogue delay module. It features two BBD lines: short, 1024 stage and long, 4096 stage, that work simultaneously and you can smoothly fade between those two, thus creating distinct multitap effect. Furthermore, an advanced BBD clock noise cancellation circuit is implemented that reduces unwanted BBD noise without filtering higher frequencies of audio signal. Most of parameters are voltage controlled, which allows to integrate the module in complex modular setups. Time This is delay time manual control. Because of BBD clock suspension circuit, delay time can be pushed in extremely long regions, however in that case BBD clock noise may appear. The Time CV is added to the knob setting. In level This is the input attenuator switch. Select among full amplitude, half amplitude and audio off. BBD mode This control smoothly fades between short and long delays. Any setting in-between will result in distinct multitap delay effect. LFO rate Adjust the internal modulation LFO rate. The internal LFO controls delay time, and it's automatically disengaged, when an external modulation signal is connected. The LED gives visual feedback on the LFO rate. LFO shape Select the LFO shape. Three shapes are available - triangle, square and in-between shape - mix of triangle and square. Input This is the audio input of the module. This is manual Dry/Wet mix. The MIX CV is added to the knob setting. Colour Even though the module has BBD clock suspension circuit, the colour switch provides extra lowpass filtering of the signal. At top setting no filtering is applied, at lower settings increasing filtering is present. Feedback This is the delay feedback manual control. In extreme clockwise settings the module goes into self-oscillation, and by adjusting delay time and BBD mode settings, the module becomes a drone machine. The FBK CV is added to the knob setting. CV level This is the Time CV level attenuator. If nothing is patched into TIME CV socket, it controls the internal LFO amplitude. WET out This is the WET signal output of the module - use it for advanced patches. Out This is the main output of the module. Time CV; FBK CV; Mix CV; These are CV inputs for Time, Feedback and Dry/Wet mix.
