ANTHEM ROOM CORRECTION (ARC) - Persona 9H Only (cont'd) TESTING PROCEDURE We recommend you measure audio response at a minimum of FIVE listening positions. Up to TEN positions can be tested with ARC if your room is unusually large (more than 40' x 40') or unusually shaped-more is not necessarily better. POSITION ONE: This "main measurement position" should be located at or just in front of the central seating position (the "Sweet Spot"). This is the "main measurement position" that is used to set the bass volume levels. ADDITIONAL POSITIONS: All additional measurement positions should be symmetrically spaced a minimum of 2 feet from position one* (see Diagram A). NOTE: If your "main measurement position" is against a wall, additional measurement positions should be in front of the seating area. Vary the distance of these positions relative to the wall by 1 foot or more from each other so they are not all the same distance from the wall (see Diagram B). Diagram B Diagram A QUICK MEASURE SPEAKER POSITION HELPER If speaker positioning is flexible, you can try using Quick Measure before running ARC. (Alternatively you can start with a full measurement and then see whether it might be necessary to re-position speakers.) To use Quick Measure: • Click the Quick Measure icon. • Click Connect and then select the device you want to measure. • Once connected, click Start to enable the sweep tone for the speaker that you are positioning. • After a few sweeps the graph will show a live update of the uncorrected measurement. It will keep running until you turn it off. • You may now move your speaker around the room and watch for when the response graph is flattest. • Leave speakers where the graph is flattest, particularly in the bass frequencies, click Stop and close the Quick Measure window, and then run ARC normally. NOTE: If you are using multiple speakers, you must repeat the process for each one. 23
