omiindustriies description of the omiindustriies Curtail 4hp audio-video voltage scaler module
Curtail is a 4hp voltage scaler used primarily to bring signals from audio Eurorack modules (+/-5V) down to video Eurorack levels (+/-1V). It features four identical channels with an input and an output. The module drops the overall voltage level by a factor of five, bringing 5V signals down to 1V. If you use signals greater than 5V, it will scale them proportionally. Curtail uses video-rate operational amplifiers, allowing you to use modules with +/-5V output levels over a broad range of frequencies.
