Exclusive use of discrete output transistors results in increased sonic transparency, outstanding
dynamic range, and high-instantaneous current capability. We've designed the power bandwidth
to be from 10Hz to 50,000Hz +/- 1dB. This ability to produce full power with linear frequency
response well beyond the threshold of human hearing insures that the amplifier's performance
over the musical spectrum will be flawless.
The Art Series amplifiers are capable of operation into a two Ohm load in a stereo
configuration and a four Ohm load in a bridged mono configuration. However, for
optimum performance a four Ohm load in stereo and an eight Ohm load in mono are
recommended. Refer to the Section on System Design for more information,
PPI's Exclusive Wire Connection System
Over the years, advances in mobile audio electronics have changed the demands
placed on the type and size of wire needed to create a high-performance mobile audio
system. To meet this need,
PPI
has created an exclusive wire connection system. This
unique, removable connection system offers the versatility of terminal strips, the
convenience of quick connect / disconnect style connectors, and the reliability afforded
by direct connection to the circuit board. The power and ground connector will accept
cable up to 6 gauge in size. The speaker/ remote tum-on connector will accept cables up
to 10 gauge in size. Refer to the Section on Installation for more information.
Fusing
The Art Series amplifier is protected from current over-load situations by a blade fuse
(Maxi - Fuse ). This type of fuse has a number of advantages. First it's available in
higher values, and its single element design is more effective than using two fuses of
lower value. Second, we could board mount it. This eliminates the use of ‘jumperwires’
(from the end-panel to the circuit board) which improves reliability. Finally, they are
readily available from any auto-supply store and are easy to service.
For safety reasons,
PPI
recommends that the power cable be fused at the positive
terminal of the battery. If this fuse (not-supplied) is not installed, and the power wire
shorts to ground (between the battery and the amplifier), a fire can result. The fuse at the
battery should be of the same value as the fuse supplied with the amplifier. Consult your
Authorized
PPI
Dealer for an appropriate in-line fuse that meets the needs of your
installation.
Installation
PRIOR TO INSTALLATION of your new Art Series amplifier it is important to consider the
following: In your profession, your abilities and expertise insure a job well done. Trained
professional car audio installers are no different. It's their chosen profession, and what they do
best.
PPI
believes so strongly in its responsibility to you, that we invest heavily in the hands-on
training of professional installers. Our comprehensive system design and installation seminar
provides our authorized dealers with the latest techniques to deal with the complexities of car
audio today. There is more than meets the eye to ensure that a car stereo reaches its fullest
potential. The trained professional, through experience, can approach, recognize, and address all
the needs of the mobile audio environment.
PPI
highly recommends that this amplifier and / or
any other mobile audio equipment be installed by a trained professional.
Tools / Parts Needed for Installation (not supplied):
Small flat blade screwdriver
Phillips screwdriver
Wire cutters
Wire strippers
Soldering iron
Solder
Flux cleaner
5 washers, 4 #6 and 1 #8 sheet metal screws
2 - ring connectors
In-line fuse holder and fuse
Speaker wire - 16 gauge or larger
Power and Ground wire - 12 gauge or larger
Heatshrink
Grommets
Silicone or similar material
Mounting
To prevent damage to the amplifier while driving, mount it in a secure place. Choosing
the appropriate location will depend upon your vehicle and the complexity of your system
design. It may be mounted in any compatible space that is convenient to your needs and
provides sufficient airflow. Adequate ventilation allows the amplifier to dissipate the heat
that develops during operation. Inadequate ventilation may result in overheating. The
thermal protection circuit will engage when the heatsink temperature reaches 75
degrees Celsius. The amplifier will automatically return to normal operation once the
heatsinkcools.
Typical mounting locations include: trunk and passenger compartment (floor or under
seat). Never mount the amplifier in a location, which would subject it to immersion or
exposure to water.
The A204 uses
a 20 amp fuse and the A404 and Ax400 use a 30 amp fuse.
