Automatic Turn-On
Selection:
The
OX
series offers three different automatic turn-on modes that can be
selected
on
the end
panel;
+
12V,
DC
Offset, and Audio. Using either the
DC Offset or Audio mode causes the
REM
terminal
to have + 12V out for turning on
additional amplifiers.
• Remote Turn-On: Set the switch to
+
12V to use the remote turn-on
lead from your source unit.
Run
18
gauge
wi
re from the Remote Turn-On Lead on your source unit to the
terminal labeled
REM
between the
amplifier's
positive and negative power
terminals.
This
is
the preferred automatic turn-on method.
• DC Offset
Turn-On:
If
Remote Turn-On
is
not
an
option, the next best setting
is
DC
Offset. The
DC Offset
mode detects a 6V
DC
offset from the
HI-Level
speaker outputs when the source unit has been turned
on.
• Signal Sense Turn-On: The Audio setting
is
the
final
alternative
for Automatic turn-on. This
is
a
Signal
Sense
turn-on method that detects the incoming audio signal
from your source unit and
automatically
turns on the
amp. This turn-on method
will
not work properly
if
the input gain
control
is
not set
appropriately.
Input Level:
The
RCA inputs
on
KICKER
OX
amplifiers
are
capable
of receiving either
Hi
or
Low-level signals
from your source unit.
If
the
only
output
available from your source unit
is
a
Hi-Level signal, simply
press
in
the
Input
Level
switch
on
the
amplifier.
Refer to the wiring section of this
manual
for
additional
instructions.
Crossover Switch:
Use the
XOVER
switch on the end panel
of the
amplifier
to set the
internal
crossover to
OFF,
HI
or
LO.
When the switch
is
set to
OFF,
a
full
bandwidth
signal
will
be
amplified. Set the switch to
HI
if
you want the
amplifier's internal
crossover to serve as a high-pass
filter.
Set the switch to
LO
if
you want the
amplifier's internal
crossover to serve as a
low-pass
filter.
Never change the crossover
"OFF/HI/LO"
switch setting
with the audio system on!
Crossover Control:
The
variable
crossover
on
the front of the OX300.2 allows
you to adjust the crossover
frequency from
50-200Hz
.
The setting for this control
is
subjective;
80Hz
is
a good place
to start.
Input
Gain Control:
The input gain
control
is
not a
volume control.
It
matches the output of the source unit to
the input
level
of the
amplifier.
Turn
the source unit up to about
3/4
volume
(if
the source unit goes to
30,
turn
it
to 25). Next,
slowly
turn
(clockwise)
the gain
on
the
amplifier
up
until
you can hear audible
distortion, then turn
it
down a
little.
Bass Boost Control:
The
variable
bass boost
control
on
the side of the
OX300.2 amplifier
is
designed to give
you increased output,
0-12dB,
at
40Hz.
The setting for this
control
is
subjective.
If
you turn
it
up, you must
readjust the input gain control
to avoid clipping
the
amplifier.
The OX125.2 uses a switch to
select
between
OdB
and +9dB of bass boost at 40Hz.
