JBL is part of the Harman International family of audio companies, a group with a common purpose: combining technology with a love of music to manufacture audio products that provide new levels of satisfaction, perfor- mance and value. T o promote diversity and creativity , JBL operates independently in research and development.
JBL wishes to thank you for selecting the Century Gold loudspeaker system. While the Century Gold loudspeakers are a new development, the ideas behind them go back to the earliest days of JBL. This system is a definitive expression of JBL ’ s quality and craftsmanship.
No. 3 The Limited Edition Century Gold Bookshelf Loudspeakers set a new standard for a new century . JBL combines the most advanced technology with a classic JBL design. These speakers continue the longstanding tradition of precise studio monitor sound for which JBL is famous.
The Century Gold also features an all-new 5" (127mm) mid-frequency transducer developed specifically for the Century Gold (Figure 2). The voice coil is 2" (50mm) in diameter and wound on edge from flat aluminum ribbon wire to a depth of precisely .
The job of the dividing network is to distribute the various frequencies to their respective transducers. The network is also designed to complement component location on the baffle.
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).
Ideally the systems should be placed at least three feet from any walls. The height, at the top of the midrange, should be at ear level. The two speakers should be equidistant from your primary listening position; the distance should be determined by the distance between the speakers.
The Century Gold loudspeakers can be connected by one of several methods. The binding posts on the rear panel of the Century Gold will accept most types of audio cable and connectors, including banana plugs and bare wire (Figure 6). Follow the hookup method that best describes your system.
The Century Gold’ s outer connection panel and internal dividing network are designed so that separate sets of speaker cable can be attached to the low-frequency transducer and midrange/high-frequency transducer portions of the dividing network. This is called bi-wiring.
Figures 8 through 10 show two bi-wiring options, single stereo amplifier and dual stereo amplifier modes. For passive and bi-wire connections, set the switch to the Normal/Bi-W ire position (Figure 8a).
The optimal method of powering the Century Gold system is with two amplifiers, one for low frequencies and one for the mid/high frequencies . It is necessary to use a high-quality active crossover module.
The Century Gold loudspeaker systems have an oiled finish. Cleaning should be done with an untreated dust cloth. Do not use conventional furniture waxes and polishes, which are not designed for oiled finishes.
