[. . . ] 23 Screen Sound System Setup and Alignment After assembling the speakers, but prior to operation, be sure that wiring connections are correct and that the installed systems are free from problems, utilizing the following steps: 1) At the loudspeaker component end of the cable run, "short" the positive and negative connections for each frequency section together, and verify that your resistance meter reads the short when measured from the amplifier end. KPT-684 2) Verify that all amplifier channels and speaker components have been wired correctly and are in proper polarity. 3) Set the electronic crossover and amplifier channels as per manufacturer recommended settings. 4) With a low level pink noise or frequency generator signal source, verify that the low frequency amplifier and processor outputs for each of the systems is feeding the proper speaker component(s). Do the same for all of the amplifier and speaker sections, across all of the installed systems. [. . . ] Level capabilities in the house should meet or exceed your specific processor system standards when speaker component specifications are factored in. Note that nominal dialogue levels in modern theaters are typically 85dB or greater, with effect and music levels at a 105dB average. When using passive crossovers (as opposed to actively dividing signals for the low, mid-bass, high frequency and optional extended high frequency sections), Klipsch recommends designing the system with 6dB of amplifier headroom. Wire Gauge The choice of gauge for speaker interconnect wire plays a major role in the power transfer efficiency between amplifiers and speakers. Signal loss per distance charts for the various gauges of speaker wire and loudspeaker impedances indicate that the largest gauge of wire should be used, whenever possible, to minimize insertion loss, amplifier loading and frequency response non-linearities. Crossovers Although passive crossovers are available for a number of the Klipsch screen and stage systems, there are advantages to using active crossovers. By actively dividing the frequency sections for the systems, less power is lost to heat in the passive crossover, and device control (damping factor) is greatly improved. In virtually every case, the speaker system performance is improved through bi- or tri-amplification. Of course, the performance improvements must be weighed against the cost of additional amplifier channels.
