1. Make sure the head unit is off and its volume control is set to minimum. 2. On BassLink�s front panel, initially set all controls to their midpoint positions, as shown in Figure 11. On BassLink�s side panel, initially set PHASE to 0° and AUTO TURN-ON to AUTO, as shown in FIgure 12. 3. Turn on the head unit and play a favorite music track that has substantial bass. Set the volume control to 75 percent of the total output (approximately 3 o�clock on rotary controls). 4. Adjust the GAIN control clockwise until the SERVO LED (on BassLink�s side panel) begins to flash with each bass note but doesn�t stay lit continuously. 5. Listen to your system, making a mental note of the amount of upper bass being reproduced. 6. Switch the PHASE control to 180° and listen again for upper bass content. There may be more upper bass, less upper bass, or no change at all. The position that provides the most upper bass is correct, but choose either setting according to your taste.

7. Adjust the CROSSOVER control clockwise or counterclockwise until you hear only low-frequency information. For example, you should NOT hear any vocals coming from BassLink when seated in the normal listening position. 8. Adjust the BASS-BOOST control clockwise or counterclockwise to suit your taste. 9. Recheck the SERVO 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 SERVO LED only flashes. 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.

POWER LED:This indicator will glow red when BassLink is operational. (Blue on Basslink X) GAIN Control: Use this control to adjust the relative volume (loudness) of BassLink with respect to the other speakers in the vehicle. CROSSOVER: Use this control to adjust the amount of high-frequency information present in BassLink�s output. A lower value signifies less high frequencies will be amplified. 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.

automatic turn-on circuit. For most speaker-level applications, slide the switch to AUTO. However, if your system produces false turn-on signals or uses a remote (REM) connection, slide the switch to OFF . REMOTE GAIN CONTROL: Use this RJ-11 jack to connect the optional remote SUB LEVEL control. SERVO LED:This indicator glows green when the subwoofer is at maximum excursion and the amplifier is modifying the output to maintain maximum performance. Be sure to monitor this indicator during BassLink setup (see Tuning BassLink). When properly tuned, the SERVO LED should light momentarily during high-level bass transients. Avoid adjustments that cause the LED to remain lit for extended periods.
