The E580 emulates the classic sounds of digital, BBD (bucket brigade), and tape-based delays with four parameters under voltage control. This 14hp wide Eurorack module accepts either +/-12V standard power or +/-15V MOTM/power. Using a 40MHz DSP and 24-bit codec, the E580 recreates the pitch-shift modulation of BBDs, including the variable bandwidth and noise floor, without costly and scarce BBD ICs. In Tape Mode, wow & flutter, tape saturation and non-linear distortions emulate classic tape units without the bulk and maintenance. There are two simultaneous audio outputs: a straight delay and a variable tapped delay. The tap position is a percentage of the main delay time. This allows very short delays (<350μs) as well as long delays (750ms). Both tap position offset and main delay time are voltage-controlled over a -5v to +5v range.
Feedback is jumper-selectable from either the tapped position or the main delay. This flexibility can generate standard rhythmic delays (feedback from main delay) or a series of pre-delay reflections (tapped delay) which sound very different from each other.

PANEL CONTROLS
| Wet/Dry |
Sets the effects mix |
| Feedback |
Applies negative feedback (CCW) or positive feedback (CW). When placed in the center, there is zero feedback. |
| Tap Offset |
Sets the percentage of the Tap Out in relation to the Delay Time. For example, if the Delay Time is set to 100ms, the Tap is set from 0-100ms. The time resolution is very fine (over 7,000 independent positions) to allows very smooth modulation of the Tap position. |
| Delay Time |
Sets the delay time for the Delay Out. Note that since Tap Out is a percentage of Delay Time, if you change the Delay Time there is a corresponding change to the Tap Out delay time. The time ratio of Delay to Tap is constant however. |
| Mode switch |
Choose from one of three delay types |
