[. . . ] It enables us to keep you posted on our latest advancements, and helps us to better understand our customers and build products that meet your needs and expectations. JBL Consumer Products Introduction JBL's SVA Series takes advantage of our latest technology to deliver incredibly clean, detailed sound. Incorporating JBL's Symmetrical Vertical ArrayTM and exclusive Bi-Radial® horn, these loudspeakers deliver sound that is distributed over a wide soundstage with pinpoint imaging. [. . . ] Because the horn should be directed at ear level in order to maximize the imaging characteristics, JBL developed an exclusive cast-aluminum adjustable spike foot that can be adjusted while the speaker is in position. The Bi-Radial horn design ­ which greatly reduces room reverberation ­ along with video-shielding, allows greater placement flexibility within the room. Ultrawide frequency response and high power handling combine to give you clear, powerful sound that you get only from genuine JBL. The SVA loudspeakers are perfect for today's Dolby* Digital recordings. The SVA Center is designed to complement any of the SVA Series loudspeakers. It is the perfect addition for re-creating the cinematic experience in your home. one. Speaker Placement Proper placement of the speakers is an important step in obtaining the most realistic soundstage possible. If there is no sound coming from one speaker, check the following: · Check the "Balance" control on your receiver/amplifier. · Check all wires and connections between receiver/ amplifier and speakers. If the system plays at low volumes but shuts off as volume is increased, check the following: · Check all wires and connections between receiver/ amplifier and speakers. · If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier. If there is low bass output, check the following: · Make sure the polarity (+ and ­) of the left and right "Speaker Inputs" are connected properly. If you are not bi-wiring your system, and there is no output from either the low- or high-frequency drivers, check the following: · Make sure the shorting straps are properly attached to the terminals. · Check all connections between processor/amplifier and each of the speakers. [. . . ] · Check all connections between processor/amplifier and each of the speakers. If you are bi-wiring your system, and there is no output from either the low- or high-frequency drivers, check the following: · Make sure the amplifier is hooked up to both the low and high terminals on each speaker. · Check all connections between processor/amplifier and each of the speakers.
