Based on the circuit created for the Voltage Lab synthesizer voice, the Analog Delay Unit (6HP) is a finely tuned effects unit designed to enhance the source material by adding depth and warmth.
The module utilizes a pair of 4,096 stage BBD chips to produce a voltage controllable analog delay signal ranging from 16ms to 340ms. Starting with a single echo, a custom feedback circuit allows the repeats to remain clean and stable until reaching self-oscillation.
Delay time is set by adjusting the delay time slider. Moving the slider up increases the delay time. Delay time can be voltage controlled by patching into the delay time CV input jack and adjusting the delay time CV trimmer.
The delay repeats slider sets the amount of repeats created by the delay. Moving the delay repeats slider all the way down will produce 1 repeat. Adjusting the slider up increases the number of repeats until the delay begins to self-oscillate. The Analog Delay Unit self-oscillates between approximately 55Hz to 500Hz depending on the position of the delay time slider.
The delay mix knob acts as a balance control between the dry incoming signal and the wet delayed signal. Turning the delay mix knob to the left weighs the output toward the dry signal. Turning the delay mix knob to the right weighs the output toward the wet signal. In theory, setting the delay mix knob at 12 o’clock creates an even mix of the wet and dry signals. In reality, the tolerance of the potentiometer, waves shape, and dry signal level all influence the location of an even 50/50 mix.
