Connect power to BassLink, as shown in Figure 5.
Also observe these installation tips:
•Use at least #12 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 to the
nearest bare metal surface. For a good connec-
tion, scrape away paint from the metal surface
and use a screw with a lock (star) washer.
Figure 5. Power connections for BassLink.
•Install a fuse holder with a 20 A fuse within 18"
of the battery + terminal (see Figure 5).
•The REM connection requires +5 to +12 Vdc
signal for BassLink to turn on remotely. Most
head units with preamp outputs provide this
remote voltage signal. For speaker-level appli-
cations, a remote connection is not required,
since BassLink’s Auto Turn-On feature will
sense voltage on the speaker wires to
automatically turn on BassLink.
IMPORTANT:To enable BassLink’s Auto
Turn-On feature, set AUTO TURN-ON to the
AUTO position (see Figure 12 on page 6).
POWER CONNECTIONS
BassLink is equipped with four line-level (RCA)
inputs and four speaker-level inputs. Any combina-
tion of line-level and speaker-level inputs may be
used to provide nonfading bass when connected to
a head unit with four outputs.
Figure 6. BassLink audio connections for a head
unit with two line-level or subwoofer (RCA) outputs.
To help you plan your installation, we included
five system applications in Figures 6 through 10
on pages 3 through 5. For more system ideas, see
your authorized Infinity car-audio dealer.
Note: The applications show the optional remote
SUB LEVEL control which installs under the dash-
board for easy in-car bass level adjustments.

BassLink provides several controls and indicators
that simplify sonic integration with virtually any
vehicle’s unique acoustic properties. They are
located on the front and side panels, as shown in
Figures 11 and 12.
Figure 11. BassLink controls on the front panel.
POWER LED:This indicator will glow red when
BassLink is operational.
GAIN Control: Use this control to adjust the rela-
tive 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.
Figure 12. BassLink controls on right side panel.
PHASE Control: Use this switch to reverse the
phase of BassLink’s output with respect to its
input. Choose the position (0°or 180°) that
sounds the best.
Note: Depending on BassLink’s orientation and
location in a vehicle, reversing the phase may
may (or may not) increase or decrease the
amount of upper bass being reproduced.
AUTO TURN-ON: For speaker-level connections,
use this switch to activate (or deactivate) BassLink’s
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.
CONTROLS AND FUNCTIONS
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 con-
trols 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-fre-
quency 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.

TROUBLESHOOTING
• PROBLEM:
POWER LED not lit.
CAUSES and SOLUTIONS:
1. Fuse is blown and needs replacement.
2. Head unit not functioning properly. Check
remote voltage, and power, ground or
remote connections.
• 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.
• PROBLEM:
BassLink sounds muddy or distorted.
CAUSES and SOLUTIONS:
1. Gain is set too high and SERVO LED is lit
constantly. Readjust GAIN control (see
Tuning BassLink on the previous page).
2. Bass is set too high. Readjust BASS BOOST
control (see Tuning BassLink on the previous
page).
3. Head-unit output is distorted or blown. See
your authorized Infinity car audio dealer.
• PROBLEM:
No output from BassLink when head-unit
fader control set to front or rear (in a 4-channel
connection).
CAUSE and SOLUTION:
Input connections are improperly wired. Verify all
connections (see Applications section)
APPLICABLE TO BASSLINK WITH LEVEL
CONTROL JACK AND BASSLINK X ONLY:
• PROBLEM:
BassLink turns on before head unit is completely on
and produces a “thump” sound.
CAUSE and SOLUTION:
For speaker-level connections, head unit is
producing a false turn-on signal. On BassLink’s
side panel, slide AUTO TURN-ON to OFF.
• PROBLEM:
BassLink’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 will remain on another 5 to 10 minutes
after sensing that audio signals are not present
before shutting down. If you prefer immediate shut-
down, set AUTO TURN-OFF to OFF.

Service Bulletin
Service Bulletin INF2000-03 - October 2000 Warranty labor rate: MINOR repair
To: All Infinity Service Centers
Model: Basslink (version w/o AUTO-ON switch or REMOTE GAIN)
Subject: Unit will not turn off
In the event you receive a Basslink subwoofer with the complaint: “The unit will not turn off, even when
the audio signal is removed, and the Remote power connection is switched off” (indicated by the
Basslink’s red LED remaining ON), perform the following modification:
1) Set the unit on a padded surface and remove all external cables.
2) On the amplifier faceplate, remove only the (14) Phillips mounting screws as shown in Figure 1.
3) Remove the amplifier assembly from the enclosure. If the amp is turned around and supported correctly,
no other connectors need to be unplugged.
4) Add these two components:
1.0 Meg ohm 1/8W resistor, Infinity part# 299-1M
.01uf, 100v mylar capacitor, Infinity part# 140-PF2A103F
Solder these parts in parallel (See Figure 2); and attach to original location shown (See Figure 3), which is in
a narrow cavity between main power supply caps and transformer T101. There are two empty pads on the
PCB for these parts with marked designators R272 and C273.
5) New gaskets must be added to the amplifier mating surface; two pairs are required, four gaskets total:
Infinity part# 723D150 and #723C150
6) Replace the amplifier assembly and tighten all mounting screws. Use caution; a hand tool is
recommended to prevent stripping the threads in the enclosure.
7) Connect +12v to the unit and a signal cable, after the unit cycles ON, (red LED should be lit), remove the
signal and remote connection only (or shut off the music source if using the Universal Interface). Unit
should turn OFF after 3 - 10 minutes (as indicated by the red LED turning OFF).

Service Bulletin
Service Bulletin INF2003-01 - January 2003 Warranty labor rate: MINOR repair
To: All Infinity Service Centers
Model: Basslink (version w/ LC - Remote Level Control); Basslink X
Subject: Dead or No Power
In the event you receive a Basslink subwoofer with the complaint: “The unit is completely dead with no
LED indicator, or sound”, check the following area on the PCB:
1) Set the unit on a padded surface and remove all external cables.
2) On the amplifier faceplate, remove
only
the (14) Phillips mounting screws as shown in Figure 1.
3) Pull amplifier assembly from the enclosure. Unplug ribbon cable at M202 and Molex speaker connector
at M101; remove amplifer.
4) Check Main PCB for a damaged (open) trace in the main 12VDC path; see exact location shown in the
two illustrations. It is near the large main filter caps, next to braided connection “5” lead from the
transformer.
5) If the trace is damaged: clean, solder, and bridge the connection with copper solder braid (solder wick
used for solder removal), or a short piece of 14 or 12 gauge buss wire.
6) After the repair is complete, new gaskets should be added to the amplifier mating surface; two pairs are
required, four gaskets total: Infinity part# 333-EVA-00836 and 333-EVA-00827.
7) Re-connect the cable and connector, replace the amplifier assembly, and tighten all mounting screws.
Use caution: a hand tool is recommended to prevent stripping the threads in the enclosure.
8) Connect 12VDC to the unit and test.
