Enclosed are several diagrams to help you plan your own system installation. Figures 1 through 3 (on pages 3 and 4) show how to configure the Kappa 255a to drive front and rear speakers and a subwoofer, tweeters and midrange speakers and a pair of subwoofers, and a tweeter/midrange component set, midbass speakers, and a subwoofer.
For system expansion, see Figure 4 on the next page.
NOTE: For simplicity, Figures 1 through 4 do not show power, remote, and input connections.
Figure 1. This wiring diagram shows a Kappa 255a amplifier driving front and rear pairs of full-range speakers and a single subwoofer.
