User manual JBL CENTURY GOLD

[. . . ] We have spared no effort, overlooked no performance factor necessary to produce the most accurate loudspeaker possible. Carefully crafted in hardwood veneers, each enclosure is finished by hand. The Limited Edition Century Gold loudspeaker system will provide many years of superb listening pleasure. Please take a moment to read this owner's manual completely before you begin. [. . . ] Slopes are chosen to match the exact response of each driver in its respective frequency range, as well as to ensure that the high-frequency transducers are adequately protected from dangerous low-frequency components. For the Century Gold system, we chose our Charge-Coupled Linear DefinitionTM Dividing Network. The inductors are all designed for highcurrent, low-distortion operation. All capacitors in the network are series/parallel connected and operated with D. C. This effectively enables the capacitors to operate in "Class A" mode, which substantially increases sonic detail, resolution, and dynamics. The low-frequency section of the dividing network is mounted on a dedicated circuit board that separates both electrical and magnetic properties from that of the midrange and tweeter sections. Additionally, the Century Gold's dividing network allows for passive, bi-wire, passive bi-amp, and full active bi-amp operation. For the full active bi-amp mode we recommend the use of a high-quality electronic crossover. No. 5 Battery Replacement The battery should be replaced approximately every 2 years. This is accomplished as follows: · Unscrew the two screws that hold the battery access cover in place. It is located on the upper portion of the dividing network, on the rear of the speaker enclosure (Figure 4). · Install the battery by aligning the battery terminals with the mating terminals in the network housing. Align male to female, female to male terminals, then snap the connectors together, assuring a tight connection.

The two speakers should be equidistant from your primary listening position; the distance should be determined by the distance between the speakers. We recommend that the angle between the speakers, at the listening position, be between 45° to 60°. For example, if the speakers are 8' apart, your listening position should be 8'­12' from each speaker. To widen the area in which the best stereo image will be perceived, turn the speaker to face the primary listening position (Figure 5). It is normally recommended that the Century Gold loudspeakers be positioned so that the high-frequency transducers are towards the inside. In some listening environments, however, the imaging characteristics may be improved by positioning the high-frequency transducers towards the outside. We suggest you experiment with the positioning of your loudspeakers to determine the ideal placement in your listening room. 3' 3' 10 ­ 15 3' 3' 10 ­ 15 Position Front View 3' Ear level when seated in listening position No. 7 3' Speaker Connections The Century Gold loudspeakers can be connected by one of several methods. [. . . ] Stains may be removed with an aerosol cleaner, following its instructions. All wiring connections should be inspected and cleaned or remade periodically. The frequency of maintenance depends on the metals involved in the connections, atmospheric conditions, and other factors, but once per year is the minimum. If a problem occurs, make sure that all connections are properly made and clean. [. . . ]
