UNDSTR
SERIES

ST4.1000D

Thank you for your decision to purchase a MICRO MINI mobile amplifier! Our
Amplifiers are
the result of extensive engineering, testing, and bullet proof
construction. Their versatility enables compatibility with optional signal
and
audio processors. These high quality MOSFET amplifiers may be configured to
allow maximum flexibility in designing different types of speaker systems.
The
MICRO MINI Series are high quality MOSFET amplifiers that are capable of
running a system full range, or they may be selected only to power subwoofers.
It is important that you closely follow the wiring instructions contained in this
Owners Manual so
that you get the most from your MICRO MINI mobile
amplifier.
High powered audio systems in a vehicle are capable of generating higher
then
"Live Concert" levels of sound pressure. Continued exposure to excessively high
volume sound levels will cause hearing loss
or damage. Also, operation of a
motor vehicle while listening to audio equipment
at high volume levels may
impair
your ability to hear external sounds such as horns, warning signals, or
emergency vehicles -thus creating a potential traffic hazard.
In the interest of safety,
MICRO MINI highly recommends listening at lower
volume levels when driving.

INSTALLATION PRECAUTIONS
NOTE: Proceed only
if
you
are qualifiedinstaller otherwise, let
your
dealer
do
it.
Always wearprotective eyewear when using tools.
•
Tum
off
all stereo and other electrical devices before you begin.
• Disconnect the negative (-) lead from your vehicles battery.
• Locate all fuel lines, brake lines, oil lines, and electrical cables when planning the
install.
• Make sure there is at least 2-inches
(5
em) around the air vents on the amplifier.
• When connecting ground points, make sure all paint is carefully scrapped away
from the auto body and contact is make with bare metal.
• Use a utility knife to trim away fabric from hole locations before drilling or cutting.
• When running power cables through sheet metal, be sure to use grommets to
properly insulate the metal edges from the wire insulation.
•
If
possible, use tubing through grommets.

MOUNTING
THE
AMPLIFIER
To
keep your
MICRO
MINI
amplifier running at top performance, choosing the
proper location it of utmost importance. For this reason the amplifier should
be mounted in a location which
will
allow air to circulate freely. A clearance
of at least 2-inches (5 em) to all sides of the amplifier
is
necessary not only for
proper cooling,
but
also for gaining access to the inputs and other variable
controls.
Be
sure that the power and signal cable connections can enter and
leave the amplifier in a straight line to avoid the risk of kinked wires causing
a malfunction.

~
MOUNTING LOCATION
Your
MICRO
MINI
amplifier comes with mounting feet that need
to
be attached
to
the amplifier
prior to installation. Once the feet are in place, use the amplifier as a template and mark the
four screw locations. Use caution to make sure there are no objects behind the installation
surface that may become damaged during drilling.
The amplifier should be protected from exposure to moisture and direct sunlight. The best
places to mount your amplifier are: The floor
of
the trunk, under the driver's seat, or on the
back
of
the rear seat. For alternate installation locations, please consult your dealer.
• Upside
down
mounting
will
compromise
heat
dissipation
through
the
heatsink
and
could
engage
the
thermal
protection
circuit.
•
Try
to
avoid
mounting
the
amplifier
on
a
subwoofer
enclosure, as extended exposure
to
vibration
may
cause
malfunction
of
the
amplifier.
•
Don't
mount
the
amplifier
so
that
the
wire
connections
are unprotected
or
are
subject
to
pinching
or
damage
from
nearby objects.
• The
DC
power
wire
must
be fused
at
the
battery
positive
(+)
terminal connection. Before
making
or
breaking
power
connections
at
the
amplifier
power
terminals,
disconnect
the
DC
power
wire
at
the battery end.
• The
power
supply
of
the
car
audio
system
must
be disconnected
until
the entire
wiring
and
installation
is
completed.

1. LINE IN (RCA) Jacks
The RCA style input jacks are for use with source units that have RCA line level
outputs. A source unit with a minimum
of 250mV is required for proper operation.
However, this input will accept levels up to 6Vrms.
2. High Level Input
If you are installing by using a high level. you do not need to connect to the remote
because.
To hear a better sound quality, you must connect the high level ground wire to the head-unit
ground.
3. GAIN Control
This control is used to match the input sensitivity of the amplifier to the particular
source unit that you are using.
4. BASS BOOST Control
This equalization circuit is used to enhance the low frequency response of the vehicle's
interior. With up to 12dB
of boost centered at 45Hz, the BASS EQ can be adjusted to
meet your own personal taste.
5. LPF (Low Pass Filter Control)
This control is continuously adjustable from. 35Hz through 250Hz at 12 dB per octave.
6. X-OVER Switch for HI/FULL/LOW
Activates the built in electronic crossover network. Warks in conjunction with the HPF
and LPF adjustable controls.
7. HPF (High Pass Filter) Control
This control is continuously adjustable from 35Hz through 250Hz at 12dB per octave
8. SUB Sonic Filter
Variable subsonic filter (20Hz -50Hz)
The subsonic filter will roll offall of the unwanted frequencies below 20Hz -50Hz.
This will allow the amplifier to use that wasted power on the audible bandwidth.
9. POWER Indicator
The GREEN when the power is on.
10. SPEAKER Terminals
As shown in the wiring diagrams, be sure to observe speaker polarity through the
system and speaker impedance. This specially tooled terminal is designed to
accommodate up to
10 gauge speaker wire.

11.GND
(Ground
Input
Connection)
A good quality ground
is
required for your
MICRO
MINI
amplifier
to
operate at peak
performance. A short length
of
cable the same gauge
as
your power cable should be
used to attache the ground terminal directly to the chassis
of
the vehicle.
12.
REMOTE
(Remote
Input
Connection)
All
MICRO
MINI
amplifiers can be turned on by applying
12
volts
to
this terminal. This can
be found on the rear
of
the source unit in the form
of
an electric antenna output, or a
remote output.
If
this is not available you can wire to the ACC position on the key. An
18
gauge wire is sufficient to run the REMOTE.
13.
+BATT
(Power
Input
Connection)
This terminal is the main power input for the amplifier and must be connected directly
to the positive (
+) terminal
of
the car battery. (see Power Cable Selection Chart on
Page 9 for recommended wire gauge for each model).
14.
FUSE
For convenience all
MICRO
MINI
amplifiers utilize common automotive ATC type fuses.
For continued protection in the event that a fuse blows, replace the fuse only with the
same value (see specifications page).
15.
REMOTE
BASS BOOST
CONTROL
This control adjusts the Bass Boost gain for the amplifier's speaker output
(0,..,
+18dB)

Disconnect the negative (-) battery terminal before you start any wiring
work! The power supply of your car audio system must
be disconnected
until the entire wiring installation
is completed.
Your MICRO MINI amplifier requires unrestricted current to deliver peak performance, so don't
"starve" your amplifier
by using small power cable. Using too small of power cable can
result in unnecessary over-heating
of the amplifier, distortion at high volume levels and
might even cause the thermal protection circuitry to shut-offthe amplifier.
• Use rubber grommets when running cables through any metal or sharp plastic, to
prevent accidental shorting
or shearing. Make sure the cables do not interfere with
normal operation
of the vehicle.
• The audio signal cables (RCA interconnects) should be kept far away from any
potential sources
of electrical interference such as electronic vehicle management
systems (relays, engine computers etc.) wiring harnesses, fuel pumps etc.
