SM 2 provides several controls that simplify sonic
integration with virtually any vehicle's unique acoustic properties.
Please read the following section carefully to familiarize yourself
with the function of each control.

Phase Switch: This switch will reverse the phase
of
Basslink
SM2's output with respect to its input. When installing
Basslink
SM2
with
an
existing factory or aftermarket system, depending on
Basslink
SM2's location
in
the vehicle and the distance between
it
and the other speakers
in
the car, changing the setting of the
phase switch may produce a discernable increase or decrease
in
the amount of upper bass reproduced. Although the position that
yields the most upper bass
is
technically correct, you may choose
the position that best suits your taste.
Level Control: This control will adjust the input sensitivity
of
Basslink
SM2. Use this control to adjust the relative volume
(loudness) of
Basslink
SM2 with respect
to
the other speakers
in
the vehicle.
Crossover Control: The crossover control adjusts the amount of
upper bass and midbass information present
in
Basslink
SM2's
output. After listening to music on the system for a time, fine-tune
the Crossover control setting to achieve a smooth transition from
the
Basslink
SM2
to the rest of the system's speakers while
avoiding a "hole," where the sounds that occur between the
Bass
link
SM2 and other speakers seem to drop out.
Bass Boost Control:
Basslink
SM2's interaction with the
acoustics of your vehicle may produce a peak or dip
in
Basslink
SM2's response. For the vast majority
of
vehicles, these peaks
or
dips occur at about 40Hz -around the frequency
of
the lowest
bass guitar note. Use the Bass Boost control
to
correct that peak
or dip. Adjustment between
0dB
and
+9dB
is
possible. Although
response without any sharp peaks or dips
is
technically correct,
you may choose the position that best suits your taste.
Audio Sense Switch:
If
you have used the High-Level inputs to
connect the
Basslink
SM2
to your system's radio/head unit
(see
Input Connections, above), set the Audio Sense switch
in
the
"On" position. This will allow the
Basslink
SM2
to sense voltage on
the speaker inputs and turn itself on when the rest
of
the audio
system turns on.
Input Load Switch: This switch has
an
effect only when you
have used the High-Level inputs to connect the
Basslink
SM2 to
your system's radio/head unit. For the lowest noise
in
most
applications, set the Input Load switch
in
the "High" position.
In
some cases, (such as when using the radio's power fader), the
"Low" position may produce better results.
Remote Connection: This connector
is
compatible with the
RBC remote volume control.
Adjustment sequence
1.
Start with Level control set to minimum, the Phase switch set
to "0" and the Crossover and Bass Boost controls rotated
to
the 3 o'clock position.
2.
Choose program material with substantial bass content and
turn the volume control on your head unit to three-quarters
of
its total output (approximately 3 o'clock on rotary controls).
3.
Adjust the gain control clockwise until the
Basslink
SM2's
volume sounds balanced with the rest
of
the system.
4.
Continue listening, making a mental note of the amount
of
upper bass present
in
your system.
5. Switch the Phase switch to "180" and recheck 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 you may choose either setting
according to your taste.
6.
Adjust the Crossover control clockwise
or
counterclockwise
until the perceived output from
Basslink
SM2,
as
heard at the
listening position, contains only low-frequency information;
i.e., you should NOT hear any vocals coming from
Basslink
SM2 when you are seated
in
the normal listening position.
7.
Adjust the Bass Boost control clockwise or counterclockwise
to suit your taste.
Note: Although this adjustment sequence will
in
most cases
provide satisfactory tuning, the actual process may include
several readjustments
of
each
of
the controls since their settings
will interact with each other. If necessary, consult your authorized
Infinity car audio dealer for help
in
tuning your system.
