It requires two or more persons to safely handle the column. 1. Loudspeaker Cables of adequate size are important to ensure that there will be no significant power loss or heating. Cable size is specified in Gauge numbers or AWG (American Wire Gauge). The smaller the Gauge number, the larger the wire size: If the Loudspeaker Cables are 25 feet (7.62m) or less, use at least 18 Gauge (AWG) wire size or larger. If the Loudspeaker Cables are 50 feet (38.1m) or less, use at least 14 Gauge (AWG) wire size or larger. If the Loudspeaker Cables are 100 feet (76.2m) or less, use at least 12 Gauge (AWG) wire size or larger. The Loudspeaker Connection Terminals can accept up to 12 Gauge (AWG) wire. 2. For additional connection information, refer to the owner smanual(s) for any component(s) connected to the XRT29 Loudspeaker. 3. The XRT29 has built in speaker protection in the form of three automatic resetting solid state devices as part of the crossover networks. Two protect the tweeters and one for the midranges drivers. The characteristics of this protection are that a certain amount of overdrive is allowed but extended periods of overdrive will trigger protection. If an obvious lack of high or mid frequencies is noticed, the Loudspeaker Protection Device may have activated. The protection devices will automatically reset when the volume control is reduced significantly and kept low until the output of the affected Loudspeaker Element returns to normal. 4. When the XRT29 Loudspeaker System is driven by more than one amplifier, the output levels of the different amplifiers connected to the Loudspeaker System must be adjusted to achieve a proper balance between the midrange and high frequencies reproduced. This adjustment is best achieved through the use of audio test equipment operated by a qualified installer. 5. The XRT29 is designed to be used with a Subwoofer, like a McIntosh PS112, in order to hear the entire audible range of sound.
