SETTING UP YOUR F/X Figure 1 WIRELESS SURROUND (continued) For most home theater receivers and processors, "Distance" settings govern channel delay for optimal performance from Dolby Digital 5.1 and 7.1 CENTER CHANNEL SUB sources. For the F/X Wireless Surround, you need to determine the actual distance from the LEFT CHANNEL RIGHT CHANNEL listening area to the loudspeaker cabinet and from the loudspeaker cabinet to the side walls. Consult your receiver/processor owners manual for proper distance setting procedures. D For Symmetrical Rooms For symmetrical rooms, whereby the distance between the loudspeaker cabinet and major F/X WIRELESS SURROUND reflecting surfaces (side walls, or large pieces of furniture) are approximately equal, the distance setting for the Surround channels appears in Table 1 (below). Example: Table 1 shows that Surround Left and Surround Right delay should be set to 30 feet for a 20 foot wide symmetrical room when the F/X Wireless Surround is placed 2 feet behind The distance setting for Surround Back the listening area. channels should simply match the actual distance of the loudspeaker behind the D listening area ("D" in figure 1). f Table 1: Symmetrical Room: Surround Right and Surround Left Speaker Distance Loudspeaker Distance In Feet Behind Listening Area 2 8 16 10 25 26 29 12 26 27 30 Room 15 28 29 31 Width (ft) 20 30 31 33 25 33 33 35 30 35 36 37 40 40 40 42 NOTE: If your room's dimensions and loudspeaker placement falls between or beyond the room width and/or placement distance values in Tables 1 or 2, then you may interpolate from the tables accordingly. NOTE: Some home theater receivers require setting speaker delay in milliseconds rather than speaker distance in feet. If you have such a receiver, you may read the values in Tables 1 and 2 as time delay in milliseconds. 10 Polk Audio Customer Service 800-377-7655 (Outside USA & Canada: 410-358-3600)
