Notes

•Sometimes due to interaction with the room, you may notice irregular results when setting the level and/or distance of the main speakers. If this happens, THX Ltd. recommends setting them manually.

•Sometimes due to the electrical complexities of subwoofers and the interaction with the room, THX Ltd. recommends setting the level and the distance of the subwoofer manually.
