1. A method of operating a plurality of sound output units positioned in a room, space or venue, each sound output unit comprising:
a position determining element,
an audio signal input,
a sound generator, and
a signal delay circuit configured to set a delay between the audio signal input and the sound generator,
the method comprising:
identifying one or more first sound output unit(s) of the plurality of sound output units,
determining, for each of one or more second sound output units, not comprising a first sound output unit, and by the positioning determining elements of the first sound output unit(s) and the second output unit:
a relative distance from the pertaining second sound output unit to the first unit(s) based on time-of-flight measurements of radio waves between position determining elements and,
based on the distance, a delay setting of the signal delay circuit of the pertaining second sound output unit.
