A Listening Position is where you, as a listener, would physically be whilst enjoying audio. This, when combined with a tailored loudspeaker configuration that includes which speakers are playing and at what levels, what audio channels they are assigned to, and their calibration levels and delays, creates a flexible and unique experience for your Listening Position.
You can create as many Listening Positions as you wish.
