This
allows
the
XTREME
4-channel
amplifier
to
utilize
a
single
set
of
RCAs
to
feed
signal
to
both
the
front

of
the
amplifier.
When
the

signal
from
the

is
routed
to
the
rear

inputs.
NOTE:
In
this
configuration,
the
rear
RCA
inputs
can
be
routed
to
another
amplifier.
The
signal
leaving
the
amplifier
is
a
copy
of
the
incoming
signal.
When
the
switch
is
disengaged,
front

are
independent.
This
allows
a

INTELLI
Q
FRONT
CHANNEL
ADJUSTMENTS
In
the
world
of
"me
too
features,"
Orion
has
developed
the
INTELLi
Q
circuit
that
makes
a
real
differ¬
ence
in
your
automotive
listening
experience.
INTELLi
Q
(INTELL\gent\y
integrated
Q
adjustment)
is
actually
an
infinitely
variable
"Q"
adjustment
found
on
the
high-pass
crossover
of
new
XTREME
and
HCCA
"Type
R"
power
amplifiers.
By
changing
the
"Q"
of
the
high-pass
from
the
industry
standard
0.707
to
any
"Q"
value
between
0.707
and
3.5
(Figure
1
),
the
high-pass
filters
essentially
becomes
two
filters:
a
single
band
parametric
equalizer
and
a
subsonic
filter.
6c/B
lOdB
By
increasing
the
"Q"
value
from
0.707
to
3.5,
the
output
is
boosted
up
to
lOdB
at
the
high-pass
crossover
frequency.
The
end-panel
display
is
clearly
marked
in
3dB
boost
steps.
Unlike
other
manufac¬
turers
"subsonic
filters,"
adjusting
the
INTELLi
Q's
high-pass
crossover
frequency
easily
performed
turning
the
crossover
pot
located
directly
to
the
right
of
the
"Q"
adjustment
(Figure
2).
The
high-pass
crossover
is
continuously
variable
from
10Hz
to
1kHz
or
100Hz
to
10kHz
via
a
xIO
frequency
selector.
By
correctly
using
the
INTELLi
Q,
you
can
increase
low
frequency
output
by
as
much
as
lOdB!
Boosting
the
lower
bass
frequency
does
not
come
without
trade-offs.
As
anyone
knows,
one
of
the
greatest
potentials
for
woofer
damage
is
caused
by
over
excursion.
Excursion
is
the
forward
and
backward
movement
of
a
woofer.
When
the
signal
to
the
woofer
is
incorrectly
boosted,
the
woofer
is
required
to
move
more
than
is
capable.
For
reference,
a
6dB
of
boost
requires
a
woofer
to
quadruple
its
excursion
to
match
the
input
signal.
Ordinary
bass
boost
equalizers
boost
without
protection.
Without
any
protection,
potential
for
damage
is
high.
The
difference
of
INTELLi
Q
What
makes
the
INTELLi
Q
different
from
all
other
equalizers
or
sub-sonic
filters
is
that
it
can
boost
lower
frequencies
the
woofer
can
produce
by
lOdB
while
preventing
over
excursion
that
can
damage
the
woofer.
The
result
is
your
woofer
with
the
loudest
low
bass
it
can
produce
reliably.
Here's
how
to
use
it.

INTELLI
Q
Setting
up
and
using
INTELLi
Q
1.
The
first
step
to
using
the
INTELLi
Q
is
to
install
the
amplifier.
Seriously,
basic
installation
techniques
for
new
XTREME
amplifiers
remain
unchanged.
Set
the
low-pass
crossover
as
you
would
in
"normal"
installations.
(Normal
Orion
of
course.)
2.
Determine
which
type
of
enclosure
you
are
using.
Refer
to
the
table
below
for
tuning
assistance.
For
example:
for
vented
enclosures,
set
the
high-pass
crossover
to
the
tuning
frequency
(port
frequency)
of
the
enclosure.
If
you
have
a
woofer
such
as
the
new
HCCA
woofers
up
to
lOdB
of
boost
can
be
used.
For
woofers
of
lesser
excursion
capability,
it
is
recommended
to
use
up
to
6dB
of
boost
only.
3.
For
RTA
tuning,
start
the
INTELLi
Q
boost
setting
at
OdB.
Using
pink
noise,
slowly
increase
the
Q
adjustment
until
the
desired
frequency
response
is
achieved.
In
situations
where
you
are
require
more
boost
than
is
recommended,
you
can
lower
the
crossover
frequency
to
get
a
similar
desired
effect.
4.
For
tuning
by
ear,
start
the
INTELLi
Q
boost
setting
at
OdB.
Using
music
the
high-energy
low
frequency
content,
slowly
increase
the
Q
adjustment
until
the
desired
sonic
performance
in
achieved.
In
situations
where
you
are
require
more
boost
than
is
recommended,
you
can
lower
the
crossover
frequency
to
get
a
similar
desired
effect

REMOTE
GAIN
REMOTE
REM
REM
GAIN
GAIN
The
remote
gain
port
allows
remote,
user
control
over
the
output
of
the
amplifier.
When
used
on
a
subwoofer
amplifier,
the
remote
gain
allows
you
to
change
the
bass
level
for
different
music
styles,
driving
conditions,
or
sonic
preferences.
Unlike
other
designs,
Orion
allows
remote
access
to
the
level
of
the
amplifier
via
a
digital
micro-controller
and
electronic
volume
that
does
not
interfere
with
the
sonic
signal
chain.
The
result
is
a
clean
clear
control
of
the
level
of
the
amplifier
that
is
unaffected
by
noise.
The
XTREME
600.4
has
two
remote
gain
ports.
This
allows
for
individual
control
of
either
the
front
or
rear
channels.
One
RGC-1
can
be
used
to
control
the
level
of
the
front
channels
and
another
RGC-1
can
be
used
to
control
the
output
level
of
the
rear
channels.
An
example
benefit
of
this
is
having
the
front
channels
in
bandpass
mode
for
midbass
and
the
rear
channels
In
low-pass
mode
for
subwoofers.
Using
two
RGC-1
would
give
the
driver
the
ability
to
control
the
level
of
both
the
midbass
and
subwoofers
for
easy
optimal
tuning.
To
utilize
this
function
simply
plug-in
a
RGC-1
into
either
the
front
or
rear
gain
ports.
The
RGC-1
is
available
from
your
authorized
ORION
dealer.
SIGNAL
INPUT
AND
OUTPUT
LEVEL
CONTROLS
XTREME
amplifiers
have
separate
front
and
rear
level
adjustments.
The
input
sensitivity
of
these
adjustments
range
from
200mv
up
to
SVrms
on
the
RCA
inputs.
This
allows
easy
integration
from
any
source
unit
either
with
RCA
outputs
or
speaker
outputs.
Refer
to
the
Testing
the
System
and
the
Adjusting
the
Sound
of
the

on
setting
up

MOUNTING
THE
XTR
AMPLIFIER
The
XTR
amplifiers
have
a
unique
mounting
system
that
can
be
con¬
figured
for
different
install
situations.
By
placing
the
removable
mounting
rails
in
the
"in"
or
"out"
positions
the
look
of
the
amplifier
mounting
can
be
changed
to
suit
personal
tastes
or
installation
re¬
quirements.
In
the
"in"
position,
you
will
not
see
the
amplifier
mounting
screws
and
the
amp
will
"float"
above
the
mounting
screws.
The
amp
can
also
be
mounted
in
a
"standard"
manner
using
the
"out"
position.

in
this
manner
you
must
mount
just
the
two
feet
to
the

before
screwing
them
to
the

The
distance
needed
between
the
verti¬

then
mount
the
amplifier
to
the
feet.
FIGURE

This
method
can
be
accomplished
by
using

or
by
simply
mounting
the

CHOOSING
MOUNTING
LOCATIONS
The
location
of
your
XTREME
amplifier
will
depend
on
several
important
issues.
Due
to
the
low
profile
size
of
the
XTREME
amplifiers,
there
are
many
possible
installation
locations
that
will
yield
satisfactory
amplifier
performance.
Always
mount
the
amplifier
in
a
place
that
protects
the
amplifier
from
the
elements.
In
addition,
mount
the
amplifier
on
a
stable,
flat
mounting
surface.
As
with
any
amplifier,
there
are
several
possible
mounting
locations
and
configurations
that
can
be
optimal.
We
will
cover
the
most
obvious
of
situations.
PASSENGER
COMPARTMENT
If
you
are
going
to
mount
the
amplifier
in
the
passenger
compartment,
make
sure
you
have
adequate
room
for
ventilation.
XTREME
amplifiers
have
been
designed
to
make
possible
under
seat
mounting.
When
mounting
your
amplifier
under
a
seat
or
similar
area,
keep
a
minimum
of
1
of
clearance
around
the
amplifier
for
adequate
cooling.
TRUNK
COMPARTMENT
Mounting
XTREME
amplifier
in
the
trunk
provides
excellent
performance
as
long
as
you
do
not
mount
the
amplifier
upside
down
or
restrict
the
airflow
around
the
heatsink
of
the
amplifier.
For
optimal
results,
mount
the
amplifier
with
the
cooling
fins
in
the
vertical
position.
This
type
of
mounting
will
yield
the
best
cooling
due
to
the
convection
effect
of
the
amplifier
chassis.

GENERAL
PRECAUTIONS
AND
INSTALLATION
TIPS
Caution:
Be
careful
not
to
cut
or
drill
into
gas
tanks,
fuel
lines,
brake
lines,
hydraulic
lines,
vacuum
lines,
or
electrical
wiring
when
working
on
your
vehicle.
Disconnect
the
vehicle's
ground
wire
at
the
battery
before
making
or
breaking
connections
to
the
audio
system's
power
supply
terminals.
Do
not
use
the
XTREME
amplifier
unmounted.
Failing
to
securely
mount
the
amplifier
can
result
in
damage
or
injury,
particularly
in
the
event
of
an
accident.
An
unmounted
amplifier
acts
like
a
heat-seeking
missile
in
the
event
of
a
crash.
Never
mount
a
XTREME
amplifier
where
it
might
get
wet.
Mount
the
XTREME
amplifier
so
the
wire
connections
will
not
be
pulled.
Route
the
wires
where
they
will
not
be
scraped,
pinched
or
damaged
in
any
fashion.
The
+12V
power
supply
wire
must
be
fused
as
close
as
possible
to
the
battery
terminal,
ideally
within
18".
Use
the
recommended
fuse
size
or
circuit
breaker
listed
in
the
Power
Connections
section
of
this
manual.
If
you
need
to
replace
the
fuse
plugged
into
the
side
of
the
XTREME
amplifier,
replace
the
fuse
with
the
same
size
ATC
type
fuse
that
came
with
the
amplifier.
If
you
are
not
sure
as
to
the
correct
value,
refer
to
the
Power
Connections
section
of
this
manual
for
details.
Using
a
higher
current
fuse
may
result
in
damage
to
the
XTREME
amplifier
which
is
not
covered
under
warranty.
NOTE:
Make
sure
all
the
equipment
in
the
system
is
turned
off
when
making
or
breaking
connections
to
the
XTREME
input
RCAs
or
speakers
terminals.
Turn
on
the
system
and
slowly
turn
up
the
volume
control
only
after
double
checking
all
wire
connections.
Power
for
systems
with
a
single
XTREME
amplifier
can
be
supplied
by
most
any
automotive
electrical
system.
Systems
with
multiple
amplifi¬
ers
may
require
a
higher
capacity
battery,
alternator
or
the
use
of
a
storage
capacitor.
WE
strongly
recommend
the
use
of
both
a
Transient
Storage
Capacitor
and
a
MBR70
with
an
extra
battery
in
larger
stereo
systems.
XTREME
amplifiers
generate
a
certain
amount
of
heat
as
part
of
normal
operation.
Be
sure
the
area
around
the
cooling
fins
is
unobstructed
to
allow
adequate
air
circulation.
Remember,
beach
blankets,
last
weeks
laundry,
school
books
and
homework
papers
located
on
top
of
the
amplifier,
do
not
improve
air
flow.

exhibit
noise;
however,
if
the
level
of

is
low
enough,
and
the

high
enough,
noise
should
not
be
a

This
means
that
it
is
very
important
that
the

II.
II.
DECK
TO
AMP.
Using
a
new
set
of
signal
cables,
connect
one
channel
from
the
output
of
the
deck
directly
into
one
channel
of
your
clean
amp.
Run
the
cables
outside
the
car
and
as
far
away
as
possible
from
the
metal
of
the
car.
(For
noise
purposes,
consider
a
2"
thick
cushion
of
electromagnetic
energy
emanating
from
every
metal
surface
in
the
car.)
A.
If
still
noisy,
congratulations,
in
all
probability
your
equalizer,
electronic
crossover,
DSP
whatchamacallit,
are
just
fine.
This
means
that
you
can't
get
your
deck
playing
quiet
with
your
amp,
right?
go
to
Step
III.
B.
If
all
is
quiet,
congratulations,
in
all
probability
your
deck
and
amplifier(s)
are
fine
-
you
obviously
have
a
problem
with
your
equalizer,
electronic
crossover,
DSP,
etc.
Skip
on
down
to
"Time
for
the
Processors."
III.
MOVE
THE
DECK.
If
you're
at
this
step,
it
is
time
to
turn
your
system
into
an
"amplified
deck"
by
temporarily
relocating
the
deck
right
ON
TOP
of
the
clean
amplifier.
Then
using
very,
very
short
signal
cables,
connect
the
output
of
the
deck
into
the
input
of
the
amp
and
test
for
noise.
Play
a
zero
bit
track
-
silence
-
and
make
sure
all
is
completely
quiet.
A.
If
still
noisy,
you're
in
a
heap
of
trouble.
We
suggest
that
you
try
another
deck
and
give
us
a
call
so
that
we
can
put
your
name
into
the
record
books.
It's
a
bad
car
audio
day
for
you.
B.
If
the
deck
is
quiet,
then
congratulations,
you're
on
your
way
to
a
successful
installation.
It
is
now
time
to
slowly,
methodically,
reinstall
the
deck
back
into
its
final
position.
Test
for
noise
each
step
of
the
way.
If
the
noise
returns,
suspect
the
signal
cables,
forget
shielding
because
it
will
have
only
a
very,
minimal
effect
within
the
audio
band.
We
highly
suggest
using
twisted
pair
cables
or
a
balanced
transmission
system
for
cable
induced
noise.
TIME
FOR
PROCESSORS
By
the
end
of
Step
III,
you
should
have
the
deck
playing
quietly
with
the
amp,
with
the
quiet
cables
quietly
routed.
So
it's
time
to
add
the
signal
processors
-
one
at
a
time
-
back
into
the
system.
Simply
repeat
Steps
II
and
III
with
the
equalizer,
then
the
electronic
crossover,
etc.
However,
before
MOVING
THE
SIGNAL
PROCESSORS
to
the
amplifier,
we
highly
suggest
that
you
supply
power
to
the
noisy
processor
from
an
isolated
power
supply
rather
than
the
car's
+12
volt
DC
and
chassis
ground.
Make
sure
to
also
connect
the
turn-on
lead
to
the
isolated
power
supply.
If
the
processor
is
now
quiet,
then
it
is
highly
probable
that
the
component
has
inadequate
isolation.
Solutions
include,
changing
components
or
permanently
adding
an
external
isolated
power
supply

SUMMATION
During
the
design
stage
of
your
vehicles,
try
to
avoid
using
extra
batteries
and
high
output
alternators.
Extra
batteries
are
nothing
but
loads
as
soon
as
the
engine
is
started
and
high
output
alternators
usually
make
more
noise
than
stock
alternators.
Also,
extra
batteries
installed
in
the
trunk
of
a
car
will
ALWAYS
force
extra
ripple
current
to
flow
over
the
car.
Install
Transient
Storage
as
close
to
the
power
supply
input
of
your
amplifier
as
possible.
The
big
caps
will
feed
the
switching
power
supplies
of
your
amps
and
minimize
the
inductive
losses
in
your
power
wiring.
Plus,
they
will
help
your
peak
system
response.
In
problem
cases,
we
highly
recommend
the
use
of
twisted
pair
cable
rather
than
coaxial
cable
for
RCA
leads.
This
practice
will
greatly
minimize
cable
induced
noise
-
especially
in
four
channel
amps!
Don't
forget
that
your
system
is
only
as
good
as
its
worst
component.
Do
NOT
use
components
with
inadequate
power
supply
isolation
or
you
will
be
asking
for
problems.
The
best
electrical
ground
on
a
car
is
the
CHASSIS
of
the
car.
Do
NOT
run
ground
leads
up
to
th
e
case
of
the
alternator
or
the
negative
battery
post.
Keep
ALL
ground
leads
as
short
as
possible.
With
properly
isolated
components,
it
does
NOT
matter
where
the
component
is
grounded.
With
inadequately
isolated
compo¬
nents,
it
matters!
With
poorly
isolated
components,
different
grounds
can
cause
different
noises.
The
deck
is
the
signal
reference
ground
for
the
entire
sound
system.
The
deck
usually
has
THREE
connections
to
the
car's
chassis:
The
black
ground
lead,
the
base
of
the
antenna,
and
the
metal-to-metal
bond
between
the
case
of
the
deck
and
the
chassis
of
the
car.
With
three
grounds,
there
is
usually
NO
cause
to
worry
about
the
ground
of
a
deck.
Amplifiers
are
usually
designed
with
adequate
power
supply
isolation.
This
means
that
it
should
not
matter
where
a
deck
is
grounded.
(Decks
are
grounded
three
times
and
amps
float.
This
is
car
audio!)
The
more
components
installed
on
a
signal
path,
the
more
chances
for
noise
to
enter
a
system.
The
more
electrical
accessories
on
a
car,
the
more
noise
will
be
produced
by
the
alternator.
This
information
was
compiled
from
more
than
20
years
of
working
in
car
audio.
