Introduction
With the
~.9~
CHAOS EPIC
amplifier series, we are introducing
in
troducing two new models , both
designed in the USA. This new series
includes a 2-channel and a 4-channel
amplifier.
These CHAOS EPIC models feature
a low pass crossover (one for each
channel on the CE404), and both high
level and RCA low level inputs on the
front panel. Input
level
can be precise
ly
controlled by variable input gain
controls.
These features help you
in
tegrate 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
player.
• CHAOS EPIC amplifier
• High input cable with connector
• Four
(4)
mounting screws
Features
Your new CHAOS EPIC amplifier
features the following:
• 2 Ohm stable stereo operation
with output power increase
• Soft turn-on circuit
• Remote turn-on/turn-off circuit
• Variable input gain control
• Nickel-plated RCA low level and
high level inputs
•
LED power indicator
• Black anodized aluminum heatsink
About 2 Ohm
operati
on
Your CHAOS EPIC amplifier has
been designed
to
operate eff:cient!y
at loads down to 2 Ohms. T
hi
s means
that you can install four 8 Ohm
speakers per channel,
when using
parallel wiring.
Doubling the number of woofers
produces an acoustic coupling effect.
This ac
oustic
coupling effect increases
the output by about 3dB for each
doubling of the number of woofers.
When operating at 2 Ohms, the
amplifiers will
in
crease their output
power
by approximately 50%.
Th
e
current draw will also increase
by
about the same amount, so be sure
you have enough current to run the
amplifiers into
a 2 Ohm load.
If you lack adequate current, your
music reproduction will be distorted.

General
precautions
Before
installing
and
using
your
new
!9~
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
ti1e
power wires 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 cord and send the amplifier to
your local dealer or service center
as
soon
as
possible.
Installation
precautions
Before you drill
or
cut any holes,
investigate your car's layout very
carefully. Take special care when 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.
Before making or breaking power
connections
in
your system,
disconnect the vehicle battery. Confirm
that your head unit 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.
SHOCK HAZARD! Do
not
open
the
case
of
this
product.
There are dangerous
voltages present within the unit. There
are
no user-serviceable parts within the unit.
Mounting
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 Ibcation.
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.

Connecting
the
amplifier
Before doing any 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 terminal
to
the
closest
point on
the
chassis
of
the car. Keep this ground wire
to
less
than 39 " (100 cm) in length. Use 8
gauge (or heavier) wire.
2.
Connect
the remote terminal
to
the
remote
output
of
the head un it using
16
gauge (or heavier) wire.
3. Connect an empty fuse holder within
18" (45 cm)
of
the
car
battery, and run
8 gauge (or heavier) cable from
this
fuse
to
the amplifier location.
4. Check that the fuse holder is empty.
Then
connect
the fuse hol
der
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
(+)
cable
must
have its
own
inline fuse.
-or-
• Run a 4 AWG cable from the fuse
holder
at
the battery
to
a distribution
block
at
or
near the amplifier's location.
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
.
CHA
OS
EPIC Amplifier User's Manual - page 6
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 unit and
the
amplifier. Then set the
volume
control
on the head unit
to
about
3/4 volume,
and adjust the amplifier'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
requires 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.
Low
Level
Input
Wiring
Low-level (RCA)
input
wiring is preferred
for
best
audio
performance
. Always use
a
high-quality
RCA
cable
for
best
audio
performance
.
NOTE:
Do
not
connect
BOTH
the
high
level
and
low
level
inputs
from
your
receiver
to
your
amplifier
at
the
same
time!

The high level input(s) should only be used when your head unit lacks RCA outputs.
If the RCA outputs are not present, connect the speaker outputs from the receiver
to
the high level input connector
of
the amplifier.
Be
sure to observe polarity to
avoid audio phase problems.

Check
to
make sure
you
have a
good
ground
connection.
Check
that the

6.5-7VDC
Check
that
there is
battery
power
on

terminal.
Check
that
there is
at
least
12v.
Check
all fuses, replace
if
necessary.
Make sure that the
