Eurorack Dual Mixer

LEDs are used to indicate when an output exceeds the nominal maximum level for Eurorack audio signals, which is 10 V peak-to-peak (-5 V to +5 V). Audio signals with a greater amplitude than that may cause clipping in some modules. The bi-colour LEDs (one for each output) are off when the output level is very low or there is no input connected; green when there is a signal up to about 8 V p-p; yellow(ish) to orange(ish) as the output approaches 10 V p-p; and red above about 10 V p-p. Note that these voltage levels are approximate and the LEDs give only a rough indication of whether the audio…
