PLANNING YOUR HOME SURROUND AUDIO SYSTEMHome surround systems are primarily intended for use with video. The SP MK II, how-ever, has been especially designed to work equally well with both non-encodedsources (CDs, cassettes, broadcast television and records) as well as surround-encoded video sources (motion pictures and broadcast television).You can use existing equipment to begin building a complete Home THX AudioSystem. Although it will not be a full-fledged THX Audio System until it is complete, theincremental improvements will be clearly heard as each step is taken toward the goal.You should start with the SP MK II THX controller and upgrade the system a step at atime by adding either the THX dipolar surround speakers or the main front speakerswith a subwoofer.PLEASE NOTE: The THX specification includes an electronic crossover for the frontspeaker system. If you are using THX speakers without the SP MK II, or other THX con-troller, some provision must be made for an appropriate crossover between the sub-woofer(s) and the front speakers.The list of equipment needed for a complete SP MK II Home THX Audio System instal-lation is fairly straightforward:• A SP MK II THX controller.• At least six channels of amplification for left, center, right front channels plus two sur-round speakers, and one or more subwoofers.• Identical THX left, center and right front speakers with appropriate stands or mount-ing brackets to facilitate aiming them directly at the primary listening area.• One or more THX subwoofers (depending on room size) designed for use with theTHX front speakers.• A pair of THX dipolar surround speakers with appropriate stands, or attached mount-ing brackets to position them at least two feet above ear level when seated.• Assorted interconnecting cables and speaker wires.A home theater also requires a large screen television and the best possible videosources. The best A/V sources are laserdisc or home satellite followed by off-the-airtelevision, cable or VHS HiFi.A 31"–35" direct-view television may be appropriate in smaller rooms but cannot impartthe theatrical experience of having your field of vision dominated by the size of theimage on the screen. Attaining this effect with a 35" television requires sitting uncom-fortably close to the screen.11
