During that period any malfunctioning or damaged units will be repaired, service and calibrated GOMA Pro offers 3 channels to amplify (up to x10 gain!), into your workshop. attenuate or polarize (attenuverter) any signal, from CV, audio to line level sources.
Connect the provided ribbon cable’s 10-pin head to the GOMA Pro, making sure the red stripe matches the one indicated on the board. Red stripe down! Place GOMA Pro on the rails of your system.
Structure GOMA Pro offers 3 channels normalized to 5 volts, processed individually by the scalers and the attenuverters. Their outputs are cascaded for mixing purposes. Back panel IN and OUT pins enable daisy chaining any modules from the GOMA family together.
Features Input normalization: fixed voltage generator While each channel handles external signals, they are normalized to a high precision 5V internal reference when no input jack is connected. The fixed voltage is processed by the scaler and the attenuverter to reach any value within the -10V to +10V range.

Features Attenuverter The 2-position switch set each channel’s knob behavior. • Attenuator, controlling the amplitude (aka “volume”) from 0% to 100%. • Attenuverter (aka polarizer) with 0% at center position. Clockwise direction provides attenuation from 0% to 100%. Counterclockwise offers similar outcome with an inverted version of the signal: positive voltage becomes negative, and vice versa.

Features Scaler GOMA Pro allows to set the attenuverter’s range with a 5-position switch featuring symbols explained in the center of the faceplate: two levels of attenuation, precise unity gain and two levels of amplification. A clipper confines the output to -/+10V, hard clipping the signal in unipolar mode, and reversing it in bipolar mode.

Features Cascade Mixer Unpatched outputs are automatically mixed with the next channel’s output, every unpatched output forming a link in a flexible mixing chain. Patching only the last output of the module turns it into a standard mixer. 1+2+3...

Features Daisy chain The cascade mixing system described above can be extended across any modules from the GOMA family, by using the included 1-pin cable to connect the OUT pin from the first module to the IN pin from the next module.
