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 XR27 Loudspeaker System. 3. The XR27 has built in speaker protection in the form of four automatic resetting solid state devices as part of the crossover networks. One protects the tweeters, one for the midranges and two for the woofers. 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, mid or low 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 XR27 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 low, midrange and high frequencies reproduced. This adjustment is best achieved through the use of audio test equipment operated by a qualified installer. 5. The XR27 is designed to be used with a Subwoofer, like a McIntosh PS112, in order to hear the entire audible range of sound.

Release the Loud- speaker Grille from the packing material by opening the slit in the packing material located on the top center. Remove the Loudspeaker Grille from the protective shipping wrap and set it aside. 5. In a similar manner, lift out the Loudspeaker System and set it aside. 6. Replace the shipping carton top onto the shipping car- ton bottom. Take the two center pieces of the just re- moved packing material and lay it down flat onto the top of the shipping carton. 7.
