The module can be used with modular signals to add a distortion/fuzz character or as a preamp for an external source such as a line source, keyboard, guitar... It’s also a great side companion for our ADDAC711 Balanced Inputs.
At the top an On/Off [BYPASS] switch routes the signal into the Effect (Up: Active) or to the bottom output gain stage (Down: Bypassed).
The amount of amplification is set by the [GAIN] control, the maximum amount of amplification can be set by the user using the [MAX GAIN] trimmer.
Up to ±5,5v the incoming signal will keep it’s integrity, beyond this point saturation will start to increase. At approx. ±6v a hard clipping will start to occur, this clipping also has a particular quality that at extreme levels it drifts the audio 0v bias reference, moving it upwards which results are similar to a Gate effect.
In the middle, an x2 op-amp based output gain stage with a clipping LED, which monitors the clipping at the output, and an [OUTPUT] control to set the output volume.
Having the top and middle gain stages provides flexibility allowing the user to completely distort the signal on the top stage and tame it’s output level with the second stage.
At the bottom, input and output for both channels (left input is normalled into right input).

ADDAC develops advanced instruments for sonic expression.
We started back in 2009 with an ambition to explore the potential crossover between analog synthesizers and computers. Because our first creations sparked a lot of attention, we decided to work hard and put them in your hands.
Today our product line is focused on a new breed of hybrid synths, that make use of the best of both the digital and analog worlds. We've grown to be able to reach thousands of enthusiastic clients, friends and collaborators. Always looking into conceptualizing and developing the most exquisite instruments, we hope you're able to join and share this passion with us.
Our solutions can be found in many personal studio throught the world, owned by musicians in several planes of stardom. We especially appreciate seeing them being used in a very wide range of musical genres.
