It re- q uires three or more persons to safely handle the Loudspeaker System. 1. Loudspeaker Cables of adequate size are important to en- s ure that there will be no significant power loss or heating. Cable size is specified in Gauge numbers or AWG (Ameri- c an Wire Gauge). The smaller the Gauge number, the larger the wire size: If the Loudspeaker Cables are 50 feet (38.1m) or less, use at least 12 Gauge (AWG) wire size or larger. If the Loudspeaker Cables are 100 feet (76.2m) or less, use at least 10 Gauge (AWG) wire size or larger. 2. For additional connection information, refer to the owners manual(s) for any component(s) connected to the XRT1K Loudspeaker. 3. The XRT1Ks built-in speaker protection incorporates five automatic resetting solid-state devices in the crossover networks. One protects the tweeters, one for the midranges and three for the woofers. The protection allows a certain amount of overdrive but extended periods will trigger pro- te ction. If an obvious lack of high, mid or low frequencies is noticed, the Protection Device may have activated. These devices will automatically reset when the volume level is reduced significantly and kept low until the output of the affected Loudspeaker Element returns to normal. 4. When the XRT1K Loudspeaker System is driven by more than one amplifier, the output levels of the different ampli- f iers connected to the Loudspeaker System must be adjusted to achieve a proper balance between the low, midrange and high frequencies reproduced. This adjustment is best achieved through the use of audio test equipment operated by a qualified installer.
