TUNING BASSLINK+4
6
SETTING THE FRONT SPEAKER AND
SUBWOOFER LEVELS
Note: Refer to page 5, ”Controls and Functions,”
for the location of controls.
1. Turn on the audio system and verify (using
the Balance and Fader controls) that the
speakers and input channels are connected
properly – when the Balance control is turned
to the left, only the left speakers should
play, and when the control is turned to the
right, only the right speakers should play.
BassLink+4’s subwoofer should play regardless
of the Fader or Balance control’s position.
2. Turn the Rear Gain (located on BassLink+4’s
end panel) and BassLink+4’s subwoofer Gain
control (located on BassLink+4’s front panel)
all the way down. Turn the Front Gain
(located on the BassLink+4’s end panel) to
1/4 volume. Only the front speakers should
be playing. Additionally, turn BassLink+4’s
Crossover control and Bass Boost control to
their midpoint positions and set BassLink+4’s
phase control to the 0° position.
3. Play a dynamic music track with substantial
bass content – Track 5 or 9 on the Phantom
Center Setup CD is suitable – and turn the
source unit’s volume control to 3/4 volume.
4. Turn the Front Gain control up until you
hear slight distortion in the music (fuzzy
or crackling sounds). Then reduce the Front
Gain control slightly until the distortion is
no longer present.
5. Turn the Sub Level control (on the remote
level control) to its maximum output setting
(fully clockwise).
6. While listening to the same track that you
used in Step 3, turn BassLink+4’s Gain control
clockwise until the servo light (located on
BassLink+4’s end panel) begins to flash with
each bass note but doesn’t stay lit continuously.
7. While sitting in the driver’s seat, listen to
your system, making a mental note of the
amount of upper bass being reproduced.
8. Switch the Phase control to the 180° position
and listen again for upper bass content.
There may be more upper bass, less upper
bass or there may be no change. The position
that provides the most upper bass is correct,
but choose either setting according to your
preference.
9. Adjust the Crossover control until you hear
only low-frequency information coming from
BassLink+4’s woofer. You should use the
highest (clockwise) position possible that
doesn’t allow any vocal information to be
audible from BassLink+4’s woofer (when you
listen in the driver’s position).
10. Adjust the Bass Boost control clockwise or
counterclockwise to suit your preference.
ABOUT THE PHANTOM CENTER CIRCUIT
Note: In order for the Phantom Center to work
properly, the front speakers MUST be connected
in correct polarity. Additionally, some factory-
installed audio systems use extensive and
nondefeatable equalization and channel delay,
which may diminish the effect of the Phantom
Center circuit.
The Phantom Center circuit provides four
tuning selections: Off, 1, 2 and 3. These settings
process the audio signal differently and provide
optimization for several different car sizes and
front speaker mounting locations. The chart
below indicates switch positions that will
probably sound best for a variety of car sizes
and speaker locations, but there is no correct
setting.You should choose the one you like best.
Note: The Phantom Center circuit affects the
midrange speaker only in switch position 1,
but may affect the separate tweeter, as well,
in switch positions 2 and 3, depending on the
tweeter’s cutoff frequency. If you have separate
tweeters mounted in the tops of the doors or
in the dashboard, and the chart indicates two
possible switch positions, the second position
may be the better choice.
Using the Phantom Center Setup CD, you’ll listen
to some instructions, a spoken setup track and
several music selections to determine the best
adjustment for your system. The first four tracks
are spoken tracks, withTrack 3 being the most
important of those tracks. Portions of Track 3
have been recorded through the equivalent of
the Phantom Center circuit. Listen to Track 3,
“Spoken Setup Track”,and choose the switch
position that provides the best illusion of a person
speaking halfway between the front speakers.
Track 3:
0:00-0:10 Switch in the Off position
0:11-0:21 Switch position 1
0:22-0:33 Switch position 2
0:34-0:47 Switch position 3
0:48-0:60 Rapid switching between
the three positions
Tracks 5 through 16 are music tracks. There
are three excerpts of songs and each excerpt
is recorded four times; once with no processing
(switch in the Off position), once through switch
position 1, once through switch position 2 and
once through switch position 3. Using the music
tracks, choose the switch position that distributes
the sound best between the right and left speakers.
You can use the following list of tracks as a guide.
