Jolin Lab Knobi
KNOBI is a multi-tool able to mix, attenuate, invert, display and multiply any kind of signal.
Knobi can serve a wide range of purposes thanks to its internal signal path that makes use of some of the most useful building blocks of analog synthesis: a 4-channel mixer, a three-range offset, an attenuverter, a fixed manual gate and lastly a cascading multiple derived from the output stage of AgogƓ.
a, b, c and d are Knobiās inputs while r is a fixed 5v reference output. The toggle switch next to d sets the range of the offset ā the big knob below the meter. Connect a signal into one of the inputs to visualize its voltage value in the three digits meter. Keep in mind that this reading happens post offset and attenuverter ā the smaller knob with (-) and (+) indications.
The pushbutton next to x4 adds a gate of 5v to the mix: with no input connected it will act as a manual gate output. Autopatch the r reference output into one of the inputs to use Knobi as a macro controller thanks the offset knob and switch to set the range and the attenuverter.
x1, x2, x3 and x4 are all cascading copies of the final signal path. Plugging a cable will break the normalization and the multiplication will reset starting from the next output. Four cables plugged in will output a copy at the same factor x1 - unity gain ā making Knobi a versatile buffered multiple.
- Width: 6HP
- Depth: 25mm
- Power: 50mA @ +12V / 30mA @ -12V
