Also, adjust in order, starting from the front right speaker. • When adjusting the speaker positions, do not move the speakers much; only move them about 1 inch towards or away from the microphone. • If you forget exactly where the microphone should be positioned or if there are problems after the procedure has been performed repeatedly, re-calibrate the distance using the Full Auto MCACC procedure, then without moving the microphone redo the Precision Distance adjustment.
