CAUTION
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.

BLUETOOTH
Bluetooth is a wireless technology standard
that
uses a 2.4
GHz
frequency to
connect to various devices over short distances. It can connect and exchange
data
with other Bluetooth enabled devices, such
as
mobile devices, computers, printers,
and
other digital home appliances, without connecting via cables.

HOWTO BLUETOOTHPAIRING THE CELLPHONE.
1)
Activate Bluetooth
on
your
cell phone.
2)
Search for Bluetooth devices
around
you in
the
Bluetooth window.
3) After a while, you will search the
"STEALTH"
in
the
Bluetooth window of
your
cell
phone. If
"STEALTH"
don't
search, after placing the position of
the
vehicle key to
OFF,
try again in
ACC
after a while
4) Touch
the
"Stealth".
Wait
a
minute
and
it
will
be
connected
with
Mini Amplifier
of
ST4.1000DB.
5) Play
music
from
your
cell
phone.
6)
Never
operate
cell
phone
while
the
vehicle
driving.
~NOTICES
FOR USING BLUETOOTH
•To avoid problems when connecting
your
device to
another
device, place
the
devices close to each other.
• Ensure
that
your
device
and
the
other
Bluetooth device are within the Bluetooth
connection range(10m). The distance may vary depending
on
the environment
the
devices are used in.
• Ensure
that
there are no obstacles between
the
headset
and
a connected device,
including
human
bodies, walls, corners,
or
fences.
·Do
not
touch
the
Bluetooth
antenna
of a connected device.
• Bluetooth uses the same frequency as some industrial, scientific, medical,
and
low
power products
and
interference may occur when making connections
near
these
types
of
products.
·Some
devices, especially those
that
are
not
tested
or
approved
by
the
Bluetooth
SIG,
may be incompatible with
the
headset.
•
Do
not
use
the
Bluetooth feature for illegal purposes (for example, pirating copies
of
files
or
illegally tapping communications for commercial purposes).
~
MOUNTING THEAMPLIFIER
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.
4

• 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 maycause 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
powerwire
must
be fused at the battery positive
(+}
terminal connection. Before
making
or
breaking power connections
at
the amplifier power terminals, disconnect the
DC
powerwire
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
250m
V
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. HPF (High Pass Filter) Control
This control is continuously adjustable from 35Hz through 250Hz at 12dB per octave
5. Bluetooth Indicator
The white LED when the your mobile phone and pairing is on.
6. POWER Indicator
The GREEN when the power is on.
7. Protection Indicator
The amplifier protection circuitry will disable the amplifier
If
Input overload, short circuit
or extremely high temperature conditions are detected. When the protection mode is in
operation, the LED indicator on the side panel will be illuminated. Indicating the amplifier
has gone into a self-preservation mode.
If
you observe that protection LED is
It,
please check the system carefully
to
determine what
has caused the protection circuit
to
engage. The amplifier can be reset by turning the remote
power offand then on again.
If
the amplifier shut down due to a thermal overload
of
an input
overload or short circuit, be sure
to
repair these conditions before attempting to power
up
the
amplifier again.
8. 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 1
0 gauge speaker wire.
9. 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.
7

10. 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.
11. REMOTE (Remote out Connection)
You
can use when tum on another amplifier
You
should be careful when connecting remote in and remote out wire.
12.
+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).
13. 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).
14. OmniAntena
When connected, the longer the communication distance.
Please use solidly fixed
it.
15. Thru-Pass Out
These inputs are signal cables from the source.
Always use high quality shieded RCA cables.
The Thru-pass allows you to build mulitiple amplifier systems without having to use splitter
cords to distribute that the signal.
Now it is simpli a matter
of
bring one set
of
RCAS into the first amplifier, tnen using the line
out RCAjacks
as
the feed to the next amplifier.

IWIRINGAND CONNECTIONS
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.
