Introduction
With the Zetar MOSFET amplifier
series, we are introducing six new
amplifiers, all designed in the USA.
This new series includes four 2-channel
amplifiers and two 4-channel
amplifiers.
All Zetar models feature both high pass
and low pass crossovers.
For further flexibility in the use of a
subwoofer, a variable bass boost
control has been included. You can
control the subwoofer level with the
remote level control module.
Planet Audio understands that
amplifiers are placed in many different
kinds of installations, so we have also
included an input sensitivity control 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
player.
• Zetar amplifier
• Remote subwoofer level control
• Remote subwoofer control cable
•HIgh input wire
• Four (4) mounting screws

General Precautions
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.
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 within the
amplifier to prevent damage, especially
in an accident.
Do not mount this amplifier so that
wire connections are unprotected, in
a pinched condition, in contact with
any metal surfaces in your vehicle, or
likely to be damaged by nearby
objects.
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.
Before installing and using your new
Planet Audio amplifier, please become familiar with all the information 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.
• 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 .

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.
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-
• Run a #0 or #2 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 amplifiers' input level
controls to just below the level of
distortion.
11. Further fine tuning of the various
controls may be necessary to obtain best
results.
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 vehicle. 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.
