BEAM TRAVEL LENGTH (Beam travel length)

A certain amount of delay must be applied to the sound from each channel so that all sound will arrive at the listening position at the same time. This menu sets the distance that sound beams travel after being output and reflected off the wall until they arrive at the listening position and adjust the delay applied to the respective channel.

The lines in the illustration below indicate the distance.
