Introduction
With the PLANET AUDIO AXIS MOSFET
amplifier series, we are introducing
eight new amplifiers, all designed in
the USA. This new series includes
two monoblock amps, two 2-channel
and one 4-channel amplifiers.
All AXIS models feature variable low
pass crossovers and variable input
gain controls. The two and four-
channel models also have high pass
crossovers.
For further flexibility in the use of a
subwoofer, a 0 /+18dB Bass Boost
selector has been included on
all amplifiers. You can control the
subwoofer level with the remote level
control module.
For flexibility in use in a variety of
installations, the two- and four-channel
models feature both line level (RCA)
and high level (speaker output) inputs,
and the monoblock models integrate
a line out for system building.
PLANET AUDIO 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.

About 2 Ohm operation
Your AXIS amplifier has been
designed to operate efficiently at loads
down to 2 Ohms. This 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 acoustic coupling effect increases
the output by about 3dB for each
doubling of the number of woofers.
When operating at 2 Ohms, 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 Ohm load.
If you lack adequate current, your
music reproduction will be distorted.
AXIS MOSFET Amplifier User's Manual - page 3
General precautions
Before installing and using your
new PLANET AUDIO amplifier, please
become 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 power wires and send the amplifier
to your local dealer or service center
as soon as possible.
* |f 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 .
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.
AXIS MOSFET Amplifier User's Manual - page 4
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.
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 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 within the unit. There are
no user-serviceable parts within the unit.
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 unit 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 holder to the
"BATT+" 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-
e 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.
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.
AXIS MOSFET Amplifier User's Manual - page 5
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!

Troubleshooting
If you experience operation or performance problems with this product, compare your
installation with the electrical wiring diagram on the previous pages. If problems persist,
read the following troubleshooting tips which may help eliminate the problems.
SYMPTOM POSSIBLE REMEDY
Amplifier will not Check to make sure you have a good ground connection.
power up. Check that the Remote Input (Turn-On) has at least 6.5-7VDC.
Check that there is battery power on the (+) terminal.
Check that there is at least 12v.
Check all fuses, replace if necessary.
Make sure that the Protection LED is not illuminated. If it is lit, shut off
the amplifier briefly, and then repower it.
Protection LED
comes on when
amplifier is
powered up.
Check for short circuits on speaker leads.
Turn down the volume control on the head unit to prevent overdriving.
Remove speaker leads, and reset the amplifier. If the Protection LED still
comes on, then the amplifier is faulty and needs servicing.
No output.
Check that all fuses are OK.
Check that amplifier is properly grounded.
Check that the Remote Input (Turn-On) has at least 6.5-7VDC.
Check that the RCA audio cables are plugged into the proper inputs.
Check all speaker wiring.
Low output.
Reset the Level Control.
Check the Crossover Control settings.
Audio present in
only one channel.
Check the RCA interconnect cables.
Check all speaker wiring.
High hiss in the
speakers.
Disconnect all RCA inputs to the amplifiers. If the hiss disappears, then
plug in the component driving the amplifier and unplug its inputs. If the
hiss disappears at this point, go on until the faulty/noisy component is
found.
It is best to set the amplifier's input level control as low as possible. The
best subjective signal-to-noise ratio is achieved in this manner. Try to set
the head unit as high as possible (without distortion) and the amp input
level as low as possible.
Squealing noise
from speakers.
Check for improperly grounded RCA interconnects.
Distorted sound.
Check that the Input Level Control is set to match the signal level of the
head unit. Always try to set the Input Level as low as possible.
Check that all crossover frequencies are properly set.
Check for short circuits on the speaker leads.
Amplifier gets
very hot.
Check that the minimum speaker impedance for the amp model is correct.
Check that there is good air circulation around the amp. In some
applications, it may be necessary to add external cooling fan(s).
Engine noise
(static type)
This is usually caused by poor quality RCA cables,which can pick up
radiated noise. Use only the best quality cables, and route them away
from power cables.
Engine noise
(alternator
whine)
Check that speaker leads are not shorted to the vehicle chassis.
Check that the RCA grounds are not shorted to the vehicle chassis.
Check that the head unit is properly grounded.
