Wires introduce an intrinsic 1 sample delay, or 1/48,000th of a second. Even accumulated delays are imperceptible for audio & performance purposes, but they can nonetheless affect audio-rate synchronization, create imprecision when simultaneity is required (for instance, the timing of two triggers to a logic gate), and so on.
This device measures the delay (in samples) between its four trigger/gate inputs, updating the results in white. The dials add compensatory delay, with updated output in blue. At the bottom, a reset button helps override windowing errors. Adjust the dials so that the blue readouts match, and you’re good to go.
It’s intended for pulses (gates & triggers), but it’ll also work with simple, standard waveforms.
