ENGLISH CONNECTIONS SPEAKER PLACEMENT The ideal surround speaker system for this unit is 7speaker systems, using front left and right speakers, a center speaker, surround left and right speakers, a surround back left and right speakers, and a subwoofer. For best results we recommend that all front speakers be of the same type, with identical or similar driver units. This will deliver smooth pans across the front sound stage as the action moves from side to side. Your center channel speaker is very important as over 80% of the dialog from a typical motion picture emanates from the center channel. It should possess similar sonic characteristics to the main speakers. Surround channel speakers need not be identical to the front channel speakers, but they should be of high quality. The surround back speaker is useful for playback of Dolby Digital Surround EX or DTS-ES. One of the benefits of both Dolby Digital and DTS is that surround channels are discrete full range, while they were frequency limited in earlier "Pro Logic' type systems. Bass effects are an important part of home theater. For optimal enjoyment a subwoofer should be used as it is optimized for low frequency reproduction. If you have full range front speakers, however, they may be used in place of a subwoofer with proper setting of the switches in the menu system. Surround Back Left Surround Left Subwoofer Front Left Front left and right speakers We recommend to set the front L and R speakers with 45-60 degrees from the listening position. Center speaker Align the front line of the center speaker with the front L/R speakers. Or place the center speaker a little backward from the line. Surround left and right speakers When the DN-A7100 is used in surround operation, the preferred location for surround speakers is on the side walls of the room, at or slightly behind the listening position. The center of the speaker should face into the room. Surround back left and right speakers Surround back speakers are required when a full 7.1channel system is installed. Speakers should be placed on a rear wall, behind the listening position. The center of the speaker should face into the room. Subwoofer We recommend using a sub-woofer to have maximum bass effect. As the subwoofer only handles low frequencies, its placement is not of particular importance when used indoors. HEIGHT OF THE SPEAKER UNITS Front left and right speakers, and a center speaker Align the tweeters and mid-range drivers on the three front speakers at the same height, as best as possible. Surround left and right speakers, and surround back speaker Place the surround left, right and surround back speakers higher than your ears by about 70cm - 1m. Also place the speakers at the same height, as best as possible. 70cm 1m Note: Use magnetically-shielded speakers for front left, right and the center speakers when the speakers are installed near the TV.
