User manual INFINITY BASSLINK T

[. . . ] Moreover, depending on orientation and mounting location, BassLink T may be "in phase" or "out of phase" with those speakers. The resulting conditions, known as constructive and destructive interference, also play a role in shaping the total frequency response of your system. BassLink T includes controls to optimize both of these conditions and their adjustment is explained in sections "Controls & Functions" and "Tuning Basslink T" . CHOOSING A MOUNTING LOCATION Choose a mounting location that does not interfere with the seats, seat mechanisms or cargo. [. . . ] To help you plan your installation, we have included two system applications in Figures 8 and 9 on pages 4 and 5.

UNDER-DASH MOUNTING Select a mounting location that allows easy access to the control while driving. Using the Remote Level Control as a template, mark and drill holes in the mounting surface. Attach the Remote Level Control using the mounting screws provided (Figure 10). IN-DASH MOUNTING Disassemble the Remote Level Control by removing the two Phillips-head screws on the front panel, rear panel and on top. Slide the Remote 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. Feed the Remote Level Control's potentiometer (with the knob removed) through the hole and use the nut provided to hold the control in place (Figure 11). In-dash mounting of the Remote Level Control. CONNECTING THE REMOTE LEVEL CONTROL TO BASSLINK T Route the cable behind the dash or other interior panels and under the carpet. Connect the RJ11 cable between the RJ11 receptacle on the BassLink T and the receptacle on the Remote Level Control (Figure 12). Remote Level Control electrical connection.

GAIN Control: Use this control to adjust the relative volume (loudness) of BassLink T with respect to the other speakers in the vehicle. CROSSOVER: Use this control to adjust the amount of high-frequency information present in BassLink T's output. BASS BOOST: Use this control to correct any perceived peak or dip in the bass response (typically around 40Hz in most vehicles). [. . . ] Adjust the BASS-BOOST control clockwise or counterclockwise to suit your taste. Recheck the PEAK LED to make sure it's flashing in time with the bass but is not lit continuously. If it is lit continuously, adjust the GAIN control counterclockwise until the PEAK LED only flashes. [. . . ]
