CITATION System Connections Note: When making connections between your amplifiers and the Citation 5.4, be certain that both the input device and the amplifier are turned off. To assure that there will be no unwanted signal transients that can damage equipment or speakers, it is always best to unplug all equipment before making any connections. Modern electronic products often have a "standby" mode that may be activated even though the product may appear to be turned off. As a general rule, avoid running any input signal or speaker wire connections in parallel with each other, or with AC power cords. This can result in undesired hum or other interference that will greatly degrade signal performance. It is highly recommended that the length of cable connecting any set of speakers be identical. For example, if there are two subwoofers in your system, make certain that the cable length connecting each speaker to the amplifier is identical, even though one speaker may be physically closer to the amplifier than the other. If one speaker has excess wire in its lead to maintain equal length, make certain the extra cable is NOT coiled in a circle, as this may form an inductor that will negatively impact the performance of your speakers. Cables or Connecting Wire To assure that the high quality signals produced by your Citation system are carried to your speakers without loss of clarity or resolution, we recommend the use of high-quality speaker cable. Many brands of cable are available, and the choice of cable may be influenced by the distance between your speakers and the amplifier, the type of speakers in use, personal preferences, and other factors. Your dealer or installer is a valuable resource to consult in selecting the proper cable for connections between your amplifier and speakers. Regardless of the brand or type of cable selected, we recommend that you use cable constructed of fine, multi-strand copper with a gauge of 14 or larger. Remember, that when specifying cable, the lower the number, the thicker the cable. Cable with a gauge of 16 may be used for short runs of less than ten feet. We do not recommend that you use any cables with an AWG equivalent of 18 or higher due to the power loss and degradation in performance that will occur. One way to insure that cables will deliver a predictable level of performance is to use cables that are Home THX certified. This certification assures that the cables have met a rigorous set of specifications designed for home theater applications. Cables that are run inside walls should have the appropriate markings to indicate listing with UL, CSA or other approved testing agency standards for that application. Questions about running cables inside walls should be referred to your installer or a licensed electrical contractor who is familiar with the NEC and/or the applicable local building codes in your area. 6
