[. . . ] But it is your listening pleasure that ultimately determines how successful we are in this endeavor. It is solely in the interest of ensuring a perfect listening experience that we ask you to faithfully follow the setup and operation procedures outlined in this owner's guide. As your owner's manual, it contains all necessary background information and detailed instructions for setting up your XS-GT1326A loudspeaker system, including unpacking the loudspeaker; selecting the correct location, speaker wire, wiring scheme and amplification; and connecting it to its associated electronics. This information will be found in Chapters 2 through 6. [. . . ] If two identical stereo amplifiers are chosen, each amplifier may be located near a loudspeaker and drive lowfrequency and high-frequency sections through short wire runs. 9 CHAPTER 5 ­ PLACEMENT AND SETUP CONSIDERATIONS The XS-GT1326A loudspeaker system is designed to be less affected by room acoustics than conventional imaging systems. However, it is very sensitive to overall symmetry, and proximity to walls, ceilings and corners. Ideally, any listening room should contain a combination of live surfaces (e. g. , walls and windows) and absorbent surfaces (e. g. , drapes, carpets, upholstery). If the distance from floor to ceiling is short, it is preferable that one surface has an absorbent covering. With the XS-GT1326A, it is most important to be able to accommodate the optimum listening area that is defined by the 100° horizontal/60° vertical coverage pattern of the horn. The listener should be centered in front of the speakers, and furniture should be of an appropriate height so that when the listener is sitting, his or her ears are level with the horn (approximately 32 inches/ 80cm), as illustrated in Figure 2. CAUTION: The XS-GT1326A is a massive system comprising materials chosen for their density, with its weight concentrated in a relatively narrow area. Verify the integrity of the floor surface before placing and setting up the speakers. If possible, the distance between the speakers should be the same as the distance between each speaker and the listening area. Angle the speaker in toward the listener so that when seated, the listener can look straight into the center of the speaker (Figure 7). As the distance increases between the speakers, increase the inward angle of the speaker. Otherwise, remove the straps to prevent possible damage to the speakers or your electronics. £ HF Trim Switch: This switch allows you to adjust the output of the high-frequency transducers to compensate for the acoustics of your room.

Each position will affect the tonal balance over a wide frequency spectrum. Experiment by placing the switch in each position while listening to familiar program material and choose the position that suits your room acoustics and listening preferences. You may find after a few months, once the transducers have settled in, that another adjustment is necessary. The switch may be adjusted using a flat-head screwdriver. ¢ Low-Frequency Input Terminals: For bi-wire configurations, connect the speaker wires for the low-frequency range to these terminals. 11 SHORTING STRAPS The XS-GT1326A is shipped with shorting straps installed between its lowfrequency and high-frequency terminals. To prepare the XS-GT1326A for bi-wire operation, these straps must be removed by completely unscrewing each binding-post knob, removing the straps, and replacing the knob. Speaker wires can then be connected to each set of terminals (see Figure 9). el Mod 00 S48 UHF HF - ­ T HF - RIM +1dB B +0d ­1dB LF T INPU ate rpor Inco g rthrid d, No ia liforn e, Ca USA SONY Figure 9. (Bi-Wire Connection Method) AMPLIFIER CONNECTIONS IMPORTANT: Turn all amplifiers off before connecting or disconnecting XS-GT1326A loudspeakers. [. . . ] If the problem remains in the same speaker, then the fault is in the loudspeaker. In this event, consult your SONY specialist dealer for assistance. If, however, the problem has moved to the other speaker, then the cause is in either a cable or an electronic component. IF THE SYSTEM PLAYS AT LOW VOLUMES BUT SHUTS OFF AS VOLUME IS INCREASED: · Check that the receiver/amplifier is on and a source is playing. · Check all wires and connections between the receiver/amplifier and the speakers.
