User manual JBL BASSWAVE

[. . . ] · If BassPro II's fuse must be replaced, be sure to use the same type of fuse and current rating as that of the original. Figure 1. Figure 2. CHOOSING A MOUNTING LOCATION FOR BASSPRO II: Choose a mounting location that doesn't interfere with cargo, the folddown rear seat or the trunk lid. The best location is usually a corner of the trunk or cargo area, as shown in Figures 1 and 2. Securely mount BassPro II to the mounting surface using the four enclosed self-tapping screws. Choose a mounting location in the front of the vehicle for the remote level control. Figure 3. [. . . ] IN-DASH MOUNTING Disassemble the Subwoofer Level Control by removing the two Phillipshead screws on the front panel, rear panel and on top. Remove the Subwoofer Level Control's bottom and side panels. Slide the Subwoofer Level Control's PC board forward to release the RJ11 connector from the back panel and remove the board along with the potentiometer, knob and connector as a single assembly. Choose a mounting location that allows easy access to the control, and provides 1-3/4" clearance behind the mounting surface. Drill a 9/32" hole in the mounting surface. Feed the Subwoofer Level Control's potentiometer shaft (with the knob removed) through the hole and use the nut and washer provided to hold the control in place (Figure 5). CONNECTING THE SUBWOOFER LEVEL CONTROL TO BASSPRO II Route the cable behind the dash or other interior panels and under the carpet. Do not route the cable outside the vehicle. Connect the RJ11 cable between the RJ11 receptacle on the BassPro II and the receptacle on the Subwoofer Level Control (Figure 6).

GAIN CONTROL: Use this control to adjust the relative volume (loudness) of BassPro II with the other speakers in the vehicle. CROSSOVER: Use this control to adjust the amount of high-frequency information present in BassPro II's output. A lower value signifies less highfrequency content. AUTO TURN-ON: For speakerlevel connections, used this switch to activate (or deactivate) BassPro II's automatic turn-on circuit. For most speaker-level applications, slide the switch to the AUTO position. If you prefer to use the remote (REM) connection, slide the switch to the OFF position. REMOTE BASS CONTROL: Use this RJ-11 jack to connect the supplied remote bass control. Make sure the head unit is off and VOLUME control is set to minimum. On BassPro II's amplifier panel, set the CROSSOVER to its maximum frequency of 120Hz, as shown in Figure 10. NOTE: If using the REMOTE BASS CONTROL, set GAIN to maximum and set the BASS CONTROL to the midpoint. Turn the head unit ON and play a selection of your favorite music track that has substantial bass. [. . . ] If you elect not to install the Remote Bass Control, adjust the GAIN control to the maximum level that provides undistorted output from the BassPro II, with the head unit's volume control at its 3 o'clock setting. NOTE: In most cases the above steps will provide you with satisfactory results. However, the actual process may require several readjustments of each control, since the settings will interact with one another. If necessary, consult your authorized JBL car audio dealer for help in tuning your system. Figure 10. 6 TROUBLESHOOTING PROBLEM POWER LED is not lit. [. . . ]
