Introduction
With the Sound Storm Laboratories
EVOLUTION
MOSFETamplifier series,
we
are introducing eight new amplifiers,
all designed
in
the USA. This new series
includes
two
monoblock
amps, four
2-channe
~
,
two
4-channel amplifiers.
All
EVOLUTION models feature
variable low pass and high pass
(except monoblock amps)crossovers
and variable input gain controls.
For further flexibility in the use of a
subwoofer, 0-+
18dB
Bass Boost
control has been included on all
amplifiers.
You
can control the
subwoofer level with the remote level
control module.
Sound Storm understands that amplifiers
are placed
in
many different kinds
of
installations,so we incorporated a very
flexible system
of
controls
in
these
amplifiers
in
order
to
help you integrate
the amp into your system regardless
of the nature of your input source.
What
is
included?
When first unpacking your new
amplifier, please check first that the
package contains all
of
the items
below.If something
is
missing,contact
the store where you purchased the
amplifier.
•
EVOLUTION
amplifier
• Remote subwoofer control
• High input cable with connector
• Four
(4)
mounting screws
Features
Your new
EVOLUTION'
amplifier
features the following:
• Class A-B operation
• Bridgeable outputs
(except
EV1500M
AND
EV2500M)
• MOSFET PWM (Pulse Width
Modulated)
Power
Supply
• 2 Q stable stereo operation
with output power increase
• Thermal and speaker short
protection
• Soft turn-on circuit
• Remote turn-on/turn-off circuit
• Variable input gain control
• Variable low pass crossover(s)
• Variable high pass crossover(s)
(2CH
/
4CH)
• Variable 0 to +18dB Bass Boost
• Nickel-plated RCA ·Iow level'and
high level inputs
• LED power and protection
indicators
•
Black
anodized heatsink
• Remote subwoofer control
About
2 0
operation
Your
EVOLUTION
amplifier
has been designed
to
operate
efficiently at loads
down
to 2
(2.
When operating at 2
(2,
the
amplifiers will increase their
output
power by approximately 50%. The
current draw will also increase
by
about the same amount, so
be
sure
you have enough current to run the
amplifiers into a 2 Q load.
If you lack adequate current, your
music reproduction will be distorted.

General
precautions
Before installing
and
using your
new
Sound
Storm
amplifier, please
be
come familiar with all the infor-
mation contained
in
this manual.
Please keep this
manual
in
a safe
place for future reference.
• Do not open or attempt
to
repair
this unit yourself. Dangerous high
voltages are present which may result
in electric shock. Refer any repairs to
a qualified service technician.
•
To
avoid risk of electronic shock
or
damage to the amplifier, do not permit
any of this equipment
to
become
damp or wet from water
or
drinks. If
this does occur, immediately unplug
the powerwires and send the amplifier
to
your local dealer or service center
as
soon as possible.
• If there
is
smoke
or
any peculiar
odor
present during use or if there is
damage
to
any
of
the component
enclosures, immediately unplug the
power wire and send the amplifier
to
your local dealer or service center as
soon
as
possible.
Installati
on p
recautions
Before you drill or cut any holes,
investigate your car's layout very
carefully. Take special care wh
en
you
work near the gas tank, fuel lines,
hydraulic lines and electrical wiring.
Never operate the amplifier when it is
unmounted. Attach all audio system
components securely
to
prevent
damage, especially
in
an
accident.

Manual -page 4
Before making or breaking power
connections
in
your system,
disconnect the vehicle battery. Confirm
that your head
un
it or other equipment
is turned off while connecting the input
jacks and speaker terminals.
If you need
to
replace the power fuse,
replace it only with a fuse identical
to
that supplied with the amplifier. Using
a fuse of a different type or rating may
result
in
damage
to
your audio system
or
your amplifier which is not covered
by
the manufacturer's warranty.
Mount
ing
the
amplifier
1. Find a suitable location
in
the vehicle
in
which to mount the amplifier.
2, Make sure there is sufficient air
circulation around the intended
mounting location.
3.
Mark the location for the mounting
hole screws by positioning the amplifier
where you wish
to
install it. Use a
scribe or mounting screw, inserted
through each
of
the amp's mounting
holes,
to
mark the mounting surface.
If the mounting surface is carpeted,
measure the hole centers and mark
with a felt tip pen.
4. Drill pilot holes
in
the mounting
surface for the mounting screws. Place
the amplifier in position, and attach
the amplifier
to
the mounting surface
securely using screws.
SHOCK HAZARD!
Do
not open the
case
of this product. There are dangerous
voltages present with
in
the unit.
Th
e
re
are
no user-serviceable parts within the unit.
Connecting
the
amplifier
Before doing
an
y wiring, look through
this manual and identify the diagrams
to
follow for power, input and speaker
connections for your particular
installation. Be sure you understand
all
the connections before you proceed.
1.
Connect the power ground termi
nal
to
the closest point on the chassis of
the
car.
Keep this ground wi
re
to
less
than
39
" (100 cm)
in
length.
always
use 4 gaowire
for
power
and ground
connecti
ons to the
amplifier
2. Connect the remote terminal
to
the
re
mote output
of
the head unit using
16 gauge (or heavier) wire.
3.
Connect
an
empty
fu
se holder with
in
18"
(46
cm) of the car battery, and run
8 gauge (or heavier) cable from this
fuse
to
the amplifier locatio
n.
4.
Check that the fuse holder is empty.
Then conne
ct
the fuse holder to the
"
BAD
+" connection on the amplifier.
5. If multiple amplifiers are being used
in
your system, either:
• Run a separate pair
of
cables from
the battery and a chassis ground point
to
each amplifier. Each
(+i
cable must
have its own inline fuse.
-or-
•
Run
a #4 cable from the fuse holder
at the battery
to
a distribution block
at or near the amplifier's locati
on.
Then
run separate cables from the amplifier
to
this distribution block and to
independent chassis ground points.
6.
Connect
all
line inputs and outputs
(if used) using high-quality cables.
Connect all speakers, following the
diagrams
in
this manual. Be sure
to
observe proper polarity to avoid audio
phase problems.
7. Insert fuse(s) into the battery fuse
holder(s).
8.
Recheck all connections before
powering up the amplifier.
9. Set all level controls
to
minimum
position, and set all crossover
controls/switches to the desired
frequency points.
10, Power up the head
un
it and the
amplifier. Then set the volume control
on the head unit to about 3/4 volume,
and adjust the amp
li
fier's input level
control(s) to just below the level of
distortion.
11. Further fine tuning of the various
controls may be necessary to obtain best
results.
Don't
misuse
the
level
control!
Do not mistake the input
level
control
for a volume control! It is designed
ONLY
to
match the output level
of
your audio source
to
the input level
of your amplifier.
Do not adjust this input level
to
maximum unless your input level
requi
res
it.
Ignoring these instructions will result
in
an
input overload
to
the amplifier,
and excessive audio distortion. It
can also cause the protection circuit
to
engage.
