BassLink T provides several controls and indica-
tors that simplify sonic integration with virtually
any vehicle’s unique acoustic properties. They are
located on the top control panel, as shown in
Figure 13.
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.

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 13. 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. 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.
8. 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 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.
