INTRODUCTION

Congratulations on your purchase of a Baja state-of-the-art power amplifier. Your selection
of a Baja car audio product indicates a true appreciation of fine musical reproduction.

Whether adding to an existing system or including your Baja amplifier in a new system, you

are certain to notice immediate performance benefits.

KEEP YOUR SALES RECEIPT

Take this time to attach your sales receipt to the manual and put in a safe place. In case of any
unforeseen reason this product may need warranty service, your receipt will be necessary to
establish purchase date.

RECOMMENDATION

A power amplifier's performance is only as good as its installation. Proper installation will
maximize the systems over all performance. It is recommended that you have our product
installed by an authorized Profile retailer. However, if you decide to install it yourself, please
carefully read through this manual and take your time to do a quality installation.

IMPORTANT! Before making any connections, disconnect the cars battery

until the installation is completed to avoid possible damage to the electrical
system.

WARNING!

Exposure to high power sound system can cause hearing loss or damage.
Listening to your system at loud levels while driving, will impair your ability to
hear traffic sounds and emergency vehicles. Use common sense when listening
to your system.

SAFETY PRECAUTIONS

Fuse amplifier's power wire at the battery.

Be sure to fuse the power wire within 12" of the car's battery. This will protect the car's
battery in case of a short circuit between the power amplifier and battery. THIS IS A MUST.
The amplifier's built-in fuse will only protect the power amplifier and not the car's battery!
The fuse value is based on the amplifiers rated power and how many amplifiers will be run off
the same power wire. Please see the specification section at the back of this manual for
your amplifiers rated value.

Use high grade wires and connectors.

To ensure maximum power transfer and secure safe connections, it is recommended to use
high grade wires and terminal rings (for connection at battery)

Do not run any wires underneath vehicle.

Exposed wires have a chance of being cut or damaged. It is best to run all wires through the
vehicle under the carpet and/or side panels. This lends to a cleaner installation and less risk of
damage.

Use caution when mounting amplifier.

Remember there are many electrical wires, gas lines, vacuum lines, brake lines as well as a gas
tank in the automobile. Make sure you know where they are when mounting the amplifier to
avoid puncturing lines, shorting wires or drilling holes in the gas tank.

Run signal wires away from electrical wires

To avoid possibility of induced noise from the car's electrical system (i.e. popping noises or
engine noise), run wires away from the car's electrical wiring.

Make all ground wires as short as possible and at the same point.

In order to reduce the chance of ground loops (i.e. engine noise), make the grounding wire as
short as possible to reduce the wire's resistance. Also, when using multiple components, make
sure all units are grounded at the same point.

Avoid sharp edges when running the wires.

To avoid the possibility of power, signal or speaker shorts, be careful not to allow the
amplifier's wires to come in contact with sharp edges. Use a grommet to protect the wire

when running through the fire wall .

FEATURES AND BENEFITS

Built-in Crossover

The Baja amplifiers include a built-in variable **high and low pass crossovers. The
crossover features a variable frequency selection of (80 Hz ~ 1.2k Hz) for precise high pass

filter and (50 Hz ~ 250 Hz) for low pass filter.

** HA1000, HA700M and HA1000M models only have a 50 Hz ~ 250 Hz low pass filter.

Bass Boost

For added low frequency performance the amplifiers are equipped with a variable 0~12 dB
bass boost @ 45Hz.

Treble Boost

For added high frequency performance two 4 channel amplifier models, HA740 & HA1040,
are equipped with a variable 0~12 dB treble boost @ 8k Hz on channels 1 & 2.

Subsonic Filter

Models HA1000, HA700M and HA1000M are equipped with a variable 20~50 Hz subsonic
filter. This filter avoidsthe reproduction of inaudible low frequencies on the amplifier

which could damage thesubwoofers because they can generate over-displacement of the
subwoofer cone.

Phase Control

Mono subwoofer amplifier models, HA700M and HA1000M are equipped with a continuously
adjustable phase lag control on the subwoofer(s) from 0 to 180 degrees. This control helps
to align the phase shift of a subwoofer for a smooth blending.

High Level Input

All Baja amps excluding 4 Channel amplifiers have high level input connector to accept high
(speaker) level signal from a factory radio without pre-amp (RCA) output.

RCA Line Output

This pre-amp signal output can be used to connect signal input to an additional amplifier or
crossover at an ease without using splitters.

Tri-Mode Capable (Excluding HA700M & HA1000M models)

If so desired the amplifier may be run in stereo and mono at the same time. For example, this
feature would allow you to run a pair of mids and tweeters in stereo and a subwoofer in mono.

Remote Turn-on

Automatically turns amplifier on when connected to the head unit's remote output. The
amplifier will turn on and off with the head unit to save current consumption. This control also
operates the reset circuit for the amplifier's protection. It must be connected with the head
unit in order to reset protection circuits.

Adjustable Input Sensitivity

Allows you to fine-tune the level matching between your source and the power amplifier.

Power and Speaker Terminals

Heavy gauge power and speaker terminals with protective covers are provided for maximum
power and signal transfer with minimal resistance.

Impedance Stability

For 2 and 4 channel amplifiers, they are stable with a 2 ohm or greater impedance load
under stereo mode and 4 ohm or greater impedance load under bridged (mono) mode. For
mono subwoofer amplifiers ( HA700M & HA1000M), they are stable with a 2 ohm or greater
impedance load.

Fuse(s)

This protects the amplifier against short circuits and excessive current.

DC Offset Protection

This circuit protects the output of the amplifier against DC voltage. If for some reason DC
voltage is detected at the output stage, the amplifier will shut down protecting the speakers
from direct current.

4

Short Circuit Protection

The circuit protects the amplifier from damage due to a short found in the speakers or wiring.
If one of the speakers or its wiring comes in contact with ground, the amplifier will shut down.
To resume normal operation, correct the problem and turn the head unit off, then back on. The
amplifier will reset and play again.

Thermal Protection

To protect the amplifier circuitry against damage caused by prolonged exposure to high
temperatures, a thermal protection circuit is activated if the amplifier reaches excessively
high operating temperature. Once the thermal circuit is activated, the amplifier will shut
down to cool off. The Amplifier will automatically turn back on once it cools down to a safe
operating temperature.

Protection Indicator

This red diagnostic LED on the side panel indicates that the amplifier has gone into protection.
Once on, the amplifier will have no output. To resume normal operation, turn head unit off and
back on again. If the amplifier immediately goes back into protection, check for high
temperature, short circuits or low impedance.
