User manual MCINTOSH XCS2K REFERENCE CENTER CHANNEL LOUDSPEAKER

[. . . ] Do not expose this equipment to dripping or splashing and ensure that no objects filled with liquids, such as vases, are placed on the equipment. WAR NING: When this Loudspeaker is connected to an amplifier that is Powered On, the connection terminals may have hazardous live voltages present with a risk of electric shock. CAUTION: When this Loudspeaker is assembled it weighs 294 pounds (133. 4 kgs). It requires three or more persons to safely move the Loudspeaker. Thank You Your decision to own this McIntosh XCS2K Loudspeaker System ranks you at the very top among discriminating music listeners. [. . . ] This results in lower distortion due to more linear magnetic flux in the voice coil gap. A good example of this low distortion is incredible smoothness and effortless clarity in the reproduction of the human voice. The Crossover Networks used in the XCS2K Loudspeaker System are phase matched between the Low Frequency, Midrange and High Frequency Sections to ensure a smooth frequency response over the entire audible range. The crossover inductors are selected so they will not add audible distortion. All the Capacitors and Inductors are chosen for high current capacity. Each section of the network utilizes it own self resetting high current PPTC type fuses to provide an extra measure of protection. Figure 2B 4 Introduction and Performance Features · Shielded Magnetic Field The XCS2K may also be used in Home Theater Installations near a television receiver or monitor without causing the television image to degrade. By design, all of the speaker's magnetic structures are inherently shielded which prevents interference. · Low Harmonic and Intermodulation Distortion The XCS2K Loudspeaker System is capable of reproducing the full dynamic range of a symphony orchestra with very low audible distortion of any kind. Figure 4 · High Power Handling The Loudspeaker Elements and Crossover Components of the XCS2K are all chosen for use with powerful amplifiers up to 2, 000 watts. · Superior Imaging Locating the Tweeters between the two rows of Midranges generates a symmetrical response for superior imaging. · Versatile Operation and Placement In addition to the regular connections, the XCS2K Loudspeaker System provides separate connections for BiAmplification and Tri-Amplification hookups, as well as Bi-Wiring and Tri-Wiring. · Extruded and Machined Side Panels and Column The top and bottom of the XCS2K Low Frequency enclosure and the Midrange/Tweeter Column enclosure are machined from extruded thick aluminum panels to be non-parallel and are given a High Gloss Black Piano Type Finish. · Gold Plated Input Connectors The XCS2K input connectors are gold plated for superior corrosion resistance and high electrical conductivity. Figure 5 Figure 6 Performance Features · High Temperature Neodymium-Iron-Boron Alloy Magnets The 3 twelve inch Woofers, 32 two inch Midranges and 20 three-quarter inch Dome Tweeters all use the NeodymiumIron-Boron magnets. This Alloy has the highest flux density per unit of volume and helps to keep the Loudspeaker System weight to a minimum while preserving the utmost in performance. 5 Dimensions The following dimensions can assist in determining the best location for your XCS2K Loudspeaker System.

The optimal method for selecting all the Loudspeaker Locations in a Home Theater System includes the use of a real time spectrum analyzer operated by an experienced system installer. An uncompromising installation would take into consideration the floor, wall and ceiling coverings, the type and placement of furniture and can even include the architectural design of the room and its construction materials. Refer to figure 11. Figure 13 Top View of Lift Areas Figure 11 Adjusting the Elevation of the Loudspeaker The acoustic output of the XCS2K Loudspeaker may be directed to line up with the height of the average ear in the prime viewing/listening area. Using an approprate tool, remove the hex head locking bolt (used during shipping) from each side of the Loudspeaker and retain them for possible future use. While two Bolt persons are loosening the hex head adjustment bolt on each side of Adjustment the LoudBolt speaker, a third person Figure 12 needs to assist by stabilizing the front of the Loudspeaker. Rotate the Loudspeaker so the center axis of the Loudspeaker is pointed toward ear level when seated in the main viewing/listening area. Figure 13 illustrates a fifteen degree angle and figure 14 is a thirty degree angle. Proceed to "How to connect" starting on page 12.
