"A brand new analog delay module designed around a pair of 4096 Bucket Brigade Delay Line (BBD) ICs to produce a distinct analog delay effect. The maximum delay time when shipped is set at 9/10ths of a second but this can be adjusted up to 2 seconds. The Analog Delay offers voltage control of the delay time, feedback, and wet signal. A true bypass switch allows the delay to be enabled and disabled quickly.

Size: 16hp
Depth: 35mm
Power Usage: 35mA

Analog Delay Control Descriptions:
Rate Control Knob / Rate CV Input:
The Rate control knob adjusts the delay time of the Analog Delay module. Left is a shorter delay and right is a longer delay. Delay time is controlled internally by a VCA. The Rate control knob controls the delay time by producing a 0-5v control voltage that controls the rate VCA. The Rate CV Input accepts 0-5v signals. The incoming voltage is added to the voltage produced by the Rate control knob to determine the delay time.

Bypass Switch:
A true bypass switch to enable or disable the analog delay effect.

Feedback Control Knob / Feedback CV Input:
The Feedback control knob adjusts the number of repeats in the wet signal. Left is fewer repeats and right is more repeats. Feedback is controlled internally by a VCA. The Feedback attenuator knob controls the amount of repeats by producing a 0-5v control voltage to to controls the feedback VCA. The Feedback CV Input accepts 0-5v signals. The incoming voltage is added to the voltage produced by the Feedback control knob to determine the number of repeats.

Wet Control Knob / Wet CV Input:
The Wet control knob attenuates the wet signal available to the Feedback output and Mix output. The amount of wet signal available to the outputs is controlled internally by a VCA. The Wet attenuator knob controls the level of wet output by producing a 0-5v control voltage to to controls the wet VCA. The Wet CV Input accepts 0-5v signals. The incoming voltage is added to the voltage produced by the Wet attenuator knob to determine the amount of wet signal available to the outputs

Dry Control Knob:
The Dry control knob attenuates the dry signal available to the Mix output.

Feedback Output / Mix Output:
The Feedback output is an output of the wet signal taken after the wet VCA. The Feedback output is the same signal that is sent to the Mix output. The Mix output is an output of the wet signal taken after the wet VCA and the dry signal taken after the dry control knob."
