BassLink II has been designed to provide the kind of high-performance lowfrequency reproduction that used to require big, clumsy enclosures, large amplifiers and complex installation. To ensure maximum performance, we strongly recommend that installation be entrusted to a qualified professional. Although these instructions explain how to install the BassLink II in a general sense, they do not show the specific installation methods for your particular vehicle. [. . . ] Remove the eight screws that hold the AMPLIFIER DOCK cover panel in place (Figure 9). Remove the screw that attaches the two wiring harnesses and connectors to the panel. Connect the wiring harness connectors to the appropriate connectors on the BassLink 4sc's circuit board. Insert the amplifier and install the eight screws that were removed in Step 2. Note: All four inputs on BassLink II must be used in order for the BassLink 4sc amplifier to function properly. CONNECTIONS Connect the front and rear speakers as shown in Figure 11. Figure 11.

They are located on the front and side panels, as shown in Figures 14 and 15. BassLink II controls on the front panel. PHASE Control: Use this switch to reverse the phase of BassLink II's output with respect to its input. Choose the position (0° or 180°) that sounds the best. Note: Depending on BassLink II's orientation and location in a vehicle, reversing the phase may, or may not, increase or decrease the amount of upper bass being reproduced. POWER LED:This indicator will glow blue when BassLink II is operational. GAIN Control: Use this control to adjust the relative volume (loudness) of BassLink II with respect to the other speakers in the vehicle. CROSSOVER: Use this control to adjust the amount of high-frequency information present in BassLink II's output. A lower value means more of the high frequencies are filtered out. BASS BOOST: Use this control to correct any perceived peak or dip in the bass response (typically around 40Hz in most vehicles). Set the control to any value between ­6dB and +3dB, according to what sounds best. AUTO TURN ON: For speaker-level connections, use this switch to activate (or deactivate) BassLink II's automatic turn-on circuit. For most speaker-level applications, slide the switch to AUTO. [. . . ] Note: In most cases, the above steps will provide satisfactory tuning. However, the actual process may require several readjustments of each control, since the settings will interact with each other. If necessary, consult your authorized Infinity car audio dealer for help in tuning your system. 6 INSTALLATION The REMOTE LEVEL control may be mounted under the dash or may be dismantled and mounted in the dash for a factory appearance. UNDER-DASH MOUNTING Select a mounting location that allows easy access to the control while driving. [. . . ]
