36 chapter 3The Menu SystemFront Speaker PlacementAlignmentAlign the center speaker evenly with (A) or slightly behind (B) (the left and right speakers), but notahead of them.AnglePlace the left and right speakers to form a 45-degree angle with your favorite viewing position toduplicate the soundtrack mixer’s perspective.HeightThe mid- and high-frequency drivers of the three front speakers should be as close as possible tothe same height. This often requires placing the center speaker directly on top (A) or beneath (B)the TV set.Preferred Surround PlacementLocationIf possible, place surround speakers to either side of the listening area, not behind it.HeightIf space permits, install surround speakers 2-3 feet above viewers. This helps to minimizelocalization effects.AimingAim surround speakers straight across the room, not down at viewers, to help create a moreopen, spacious surround sound field.Alternative Surround PlacementRear WallIf rear wall mounting is the only choice, aim the speakers at each other (A), towards thefront (B) or towards the sidewalls (C, D). Experiment with placement until sounds seem tosurround you, rather than come from behind you.Courtesy Dolby LaboratoriesCourtesy Dolby LaboratoriesSpeaker SettingUse this option to select parameters for the analog 5.1 channel output.• 2chSelect when a 2 channel stereo system is connected to the player.• 5.1chSelect when a 5.1 channel surround system is connected to the player.When you select 5.1 ch, you can set the speaker sizes, distance to each speaker and the crossover frequency.Crossovers split the audio signal into separate frequency bands and sends the frequencies to the speakers thatare capable of playing them. For example, if your small speakers can’t play frequencies lower that 80Hz, thecrossover will separate the audio signal so frequencies lower than 80Hz will go to a larger speaker that is capavleof playing them. You can choose between 80 Hz/100 Hz/120 Hz.1 Select a speaker by pressing the arrow buttons, and press OK.2 Select the size by pressing the up/down buttons, and press OK.menu5.indd 36 3/8/06 4:50:01 PM
