Connect power to BassLink T, as shown in Figure 6. Also observe these installation tips:

•

Use at least #10 AWG wire for the +BATT (+12 Vdc) and GND (ground) connections. If needed, use at least a #20 AWG wire for the REM (remote) connection.

•

Route all power wires through a grommet in the vehicle’s firewall. If a factory grommet is unavailable, install one.

•

Connect a short GND wire from BassLink T to the nearest bare metal surface. For a good connection, scrape away paint from the metal surface and use a screw with a lock (star) washer.

•

Install a fuse holder with a 25 A fuse within 18" of the battery’s positive (+) terminal (see Figure 6).

•

The REM connection requires +5 to +12 Vdc signal to turn on BassLink T. Most head units with preamp outputs provide this remote voltage signal. For speaker-level applications, a remote connection is preferred but not required, since BassLink T’s Auto Turn-On feature will sense voltage on the speaker wires to automatically turn on BassLink T.

IMPORTANT: To enable BassLink T’s Auto Turn-On feature, set the AUTO TURN-ON switch to the AUTO position (see Figure 12 on page 7).

BassLink T provides several controls and indicators that simplify sonic integration with virtually any vehicle’s unique acoustic properties. They are located on the top control panel, as shown in Figure 12.

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. 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 your preference.

PHASE Control: Use this switch to reverse the phase of BassLink T’s output with respect to its input. Choose the position (0° or 180°) that sounds the best.

Figure 12. BassLink T control panel.

NOTE: Depending on BassLink T’s orientation and location in a vehicle, reversing the phase may (or may not) increase or decrease the amount of perceived upper bass being reproduced.

AUTO TURN-ON: For speaker-level connections, use this switch to activate (or deactivate) BassLink T’s automatic turn-on circuit.

REMOTE LEVEL CONTROL: Use this RJ11 jack to connect the Remote Level Control (see page 6).

PEAK LED:This indicator glows red when the subwoofer is at maximum output. Be sure to monitor this indicator during BassLink T setup (see Tuning BassLink T). When properly tuned, the PEAK LED should light momentarily during high-level bass transients. Avoid adjustments that cause the PEAK LED to remain lit for extended periods.

POWER LED:This indicator will glow blue when BassLink T is operational.

CONTROLS AND FUNCTIONS

1. Unplug the RJ11 cable that connects the Remote Level Control to BassLink T.

2. Make sure the head unit is off and its volume control is set to minimum.

3. On BassLink T’s top panel, initially set all controls to their midpoint positions, as shown in Figure 12. On BassLink T’s top panel, initially set PHASE to 0°.

4. Turn on the head unit and play a favorite music track that has substantial bass. Set the head unit’s volume control to 75 percent of the total output (approximately 3 o’clock on rotary controls).

5. Adjust the GAIN control clockwise until the PEAK LED (on BassLink T’s top panel) begins to flash with each bass note but doesn’t stay lit continuously.

6. Listen to your system, making a mental note of the amount of upper bass being reproduced.

7. S witch 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.

8. Adjust the CROSSOVER control clockwise or counterclockwise until you hear only lowfrequency information. For example, you should NOT hear any vocals coming from BassLink T when seated in the normal listening position.

9. Adjust the BASS-BOOST control clockwise or counterclockwise to suit your taste.

10.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.

11.Reconnect the RJ11 cable between the Remote Level Control and BassLink T. You may then use the Remote Level Control to adjust the level of the bass to suit your taste and/or different program material.

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.

TROUBLESHOOTING

•

PROBLEM:

POWER LED is not lit.

CAUSES and SOLUTIONS:

1. Fuse is blown and needs replacement.

2. Head unit is not functioning properly. Check remote voltage, and power, ground or remote connections.

PROBLEM:

No output from BassLink T when head-unit fader control is set to front or rear.

CAUSE and SOLUTION: Input connections are improperly wired. Verify all connections (see

Applications, starting on

page 4).

•

PROBLEM:

BassLink T produces a loud humming noise with the system OFF when using speaker-level inputs.

CAUSE and SOLUTIONS: This problem is caused by a feedback loop between your speakers and the high-level inputs of BassLink T.

•

PROBLEM:

POWER LED is lit but there is no bass.

CAUSES and SOLUTIONS:

1. Inputs are not connected. Check connections.

2. Head-unit fader control is not set properly. Adjust head-unit fader control to feed audio signals to BassLink T.

•

PROBLEM:

BassLink T sounds muddy or distorted.

CAUSES and SOLUTIONS:

1. Gain is set too high and PEAK LED is lit

constantly. Readjust GAIN control (see Tuning BassLink T on page 7).

2. Bass is set too high. Readjust BASS BOOST control (see Tuning BassLink T on page 7).

3. Head-unit output is distorted or blown. See your authorized Infinity car audio dealer.

•

PROBLEM:

BassLink T turns on before head unit is completely on and produces a “thump” sound.

CAUSE and SOLUTION: For speaker-level connections, BassLink T is receiving a false turn-on signal. On BassLink T’s top panel, slide AUTO TURN-ON to OFF and use the Remote (REM) connection.

•

PROBLEM:

BassLink T’s POWER LED remains on after head unit is turned off.

CAUSE and SOLUTION: For speaker-level connections, this is normal operation when AUTO TURN-ON is set to ON. BassLink T will remain on another 5 to 10 minutes after sensing that audio signals are not present before shutting down.

Choose one of the following solutions:

1. Connect a wire from the REMOTE terminal on BassLink T to the remote turn-on of your head unit or to the vehicle’s accessory circuit. On the control panel, slide the AUTO-ON switch to the OFF position.

2. Connect the supplied capacitors between each

of the speaker outputs of the head unit and the speaker’s positive lead. Connect each positive lead of BassLink T’s high-level inputs to the head-unit side of the capacitors. Use one capacitor per speaker input channel.

DISASSEMBLY PROCEDURE FOR BASSLINK T (ACCESS TO AMPLIFER, DRIVERS)

1) On a protected work surface, stand the unit up so the back panel is facing you.

2) Remove the (12) Phillips screws holding the b lack heatsink to the enclosure. Do not remove the heatsink at this time.

3) Remove the (36) Phillips screws holding the back panel to the ma in enclosure. Note in the area of the heatsink, two screws are shorter, machine screws.

4) Carefull y separate th e bac k pa nel from the mai n encl osure; try not to damage the O-r i ng th at m ay be adhered to both sides of the enclosure, preventing its separation. Note the LED wires from the heatsink area routed to the amplifier; unplug the 2 lead connection at female connector M2 on the amplifier. Set the heatsink and LED w/ wires aside.

5) Unplug the woofer wires from the terminals.

6) Completely separate the two enclosure halves.

SERVICING THE INPUT/PREAMP SECTION

7) Remove the (8) Phillips screws holding the cover plate to the enclosure.

8) With a wood chisel or similar tool, carefully pry the plastic cover away from the cup, working around the perimeter, until the cover is detached. If the cover is damaged during this procedure, order part# 309-ABS-05002.

REASSEMBLY

9) If the cover to input/preamp section was detached, apply a bead of silicon sealer or similar adhesive around the perimeter of the cover, in the sealing groove. Without this adhesive, there may be an air leak which would affect performance. Press the cover into place.

10) Attach the woofer wires.

11) Before the enclosure can come together, connecting the heatsink/LED wire presents a challenge if not correctly done. The LED wire must thread through the enclosure, the small hole in the aluminum heatsink plate, and back into the M2 connector on the amplifier. The position in which this is best achieved is with Basslink T laying flat side down on a surface, woofer side up. Partially bring the enclosure halves together, and work through the remaining gap near the heatsink end. See illustration .

12) Make sure the O-ring around the perimeter of the enclosure is intact and in place. Make sure the two shorter machine screws are used in the back panel, in the area near the heatsink.

13) Replace all enclosure and heatsink screws.
