User manual JBL PSW1200

[. . . ] PLACE OF INSTALLATION Place the unit on a firm and level surface. Avoid installing your unit under the following conditions: · Moist or humid places. · Places exposed to direct sunlight or close to heating equipment. · Places subject to excessive vibration or dust. [. . . ] INPUTS Your PSW subwoofer has both line-level and speaker-level input connections. Review your receiver/T. V. /source amplifier instruction manual to see which outputs your equipment provides, then follow the appropriate instructions below. "Line Input" - Use the RCA (phono) input jacks labeled "Line Input" when connecting from a line-level device, such as a preamp, crossover, signal processor, or when using any of the line-level outputs on the rear of your receiver/T. V. /source amplifier. If your receiver has a single RCA output for sending the signal to the subwoofer, connect it to both R & L input jacks by using a "y" adapter (not included). Many stereo/ large screen T. V. s have stereo (R & L) RCA jacks for sending the signal to external audio equipment. Your subwoofer connects to these using both the R & L input jacks. 1) 5 "Speaker Level Input (from amplifier)" ­ Use these inputs when connecting to the speaker out (speaker mains) of your receiver/T. V. /source amplifier. Run speaker wires from the speaker output terminals (usually coded red and black) on the rear of your receiver/T. V. /source amplifier to the red and black input terminals labeled "Speaker Level Input (from amplifier)" on the PSW subwoofer. 2) Preparing the speaker level hookup wire Your JBL dealer can recommend suitable cables, or you can buy wire at most hardware stores. High quality connectors and cable offer consistent performance that does not deteriorate over time. We recommend #16 AWG twoconductor insulated wire as a minimum size. If your PSW subwoofer is more than 30 feet (10 m) from your receiver/T. V. / source amplifier, use larger diameter wire. First measure the distance from your receiver/T. V. /source amplifier to your PSW subwoofer. Strip off 3/8" of insulation from both ends of each conductor wire. Twist each set of thin wires into a tightly-bunched spiral. Now find a visual difference between the two conductors of each molded pair of speaker wire. + R ­ ­ L + R L Receiver, TV, or Amplifier Figure 1: Line Level Input Connection Discrete Output, High Current Powered Subwoofer -180° Phase 0° PSW-1200 90 150 Hz 1 10 Crossover Frequency Volume R L Low Level Input CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN High Level Input AVIS!RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR +R- -L+ High Level Output 120VAC 60Hz 2A LR 104580 + R ­ ­ L + R L Receiver, TV, or Amplifier Discrete Output, High Current Powered Subwoofer PSW-1200 90 150 Hz 1 10 -180° Phase 0° Figure 2: Speaker Level Input Connection CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN Crossover Frequency Volume R L Low Level Input High Level Input AVIS!RISQUE DE CHOC ELECTRIQUE NE PAS OUVRIR +R- -L+ High Level Output 120VAC 60Hz 2A LR 104580 6 These differences can be a different color wire (copper or "silver"); a strand of yarn in one conductor; thin, raised ribs on one part of the outer insulation; or a printed "+" marking on one of the insulators. It doesn't matter which of the two strands of wire go to (+) and (­) on your receiver/T. V. / source amplifier and PSW subwoofer, just be sure to connect both left and right hookup wires identically. Push down on the button below the terminal and insert the wire through the hole. [. . . ] GENERAL CARE Use a damp cloth for cleaning your PSW subwoofer cabinet. Do not use detergents or other cleaners. TROUBLESHOOTING / SERVICE Your PSW subwoofers should only be serviced by an authorized JBL repair station. Woofers are replaceable by repair station only.
