Dear customer,

Congratulations on your purchase of a Bazooka high-performance amplifier. At Bazooka,
we are fanatics about accurate music reproduction. Your selection of our products for
your sound system indicates that quality sound is also important to you too. At SAS, we
take great pride in manufacturing revolutionary audio products, and through the years of
engineering expertise, hand craftsmanship and critical testing procedures, we have
created this high-performance series of amplifiers. We hope that you will take as much
pride in owning and using one of these high-quality audio products as we do designing and
manufacturing them.

When properly installed and operated, your Bazooka BA amplifier will give you years of
clean uninterrupted sound reproduction. Therefore, we urge you to take a few minutes to
carefully read through this manual. It will explain all of the features of your amplifier and
help insure trouble free installation.

Sound can be deceiving. Over time your hearing comfort level adapts to higher volumes of
sound. What may have sounded normal can actually be too loud and harmful to your hearing.
Guard against this by setting your equipment at a safe level before your hearing adapts.

To establish a “safe level”,

Start with your volume control at a low setting.

Slowly increase the volume control until you can hear comfortably, clearly and
without distortion.

Once you have established a comfortable “sound level”, make a note of this
position and do not go above this setting

Taking a minute to do this will help prevent your hearing from being damaged and allow you
to enjoy listening to music throughout your lifetime.

SAFETY PRECAUTIONS

Fuse amplifiers 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 not the car's battery!

Use high grade wire connectors.

ENGLISH

To ensure maximum power transfer and secure safe connections, it is recommended to
use high grade barrier spades (for connection at amplifier if applicable) 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
amplifiers wires to come in contact with sharp edges. Use a grommet to protect the wire
when running through the fire wall .

FEATURES AND BENEFITS

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.

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.

Tri Mode Capable (BA260, Ba460, BA2100 AND BA2150HC )

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 mid and tweeters in stereo and a sub-woofer
mono (See Page 12).

Built-in Crossover

The “BA”amplifiers include a built-in variable **high and low pass crossovers. The
crossover features a variable frequency selection (60Hz ~ 400Hz) for precise high or low
pass filtering. **Except BA1150, 1300, 1500 & 1900 which have a 40 ~ 130Hz low pass filter.

ENGLISH

Bass Boost

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

Line Out

One set of full range line outputs have been provided for convenient connection to
additional amplifiers in the system. (All models except BA260 & BA2100)

BA AMPLIFIERS

Power Fusing

This protects the amplifier against short circuits and excessive current.

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.

ENGLISH

Adjustable Input Sensitivity

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

5

MOUNTING LOCATION

Before you start the installation, it will be necessary to find a mounting location for the
amplifier. Find a location in which the amplifier will receive adequate ventilation in order
to dissipate the heat it develops during operation. Two popular mounting locations are in
the trunk or under the seat.

Select the location in which you wish to mount the amplifier. Use caution when mounting
amplifier, there are many 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. Once you are ready, use a
pencil to mark the mounting holes in the bottom panel. After you have marked the locations
of the holes move amplifier out of the way and drill small starter holes to make the tapping
screws easier to install. Use provided screws to tighten down the amplifier.

IMPORTANT! Before making any connections, disconnect the car’s battery until the

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

Connect the amplifier to the car's battery.

At times, the amplifier will need to draw large levels of current that cannot be provided by
any circuit in the car's fuse box. We recommended using an 4 to 8 gauge power wire for
your connections depending on the amplifier and length of the wire. Strip one end of the
wire to connect to the terminal on the amplifier marked +12V. Loosen screw terminal and
connect bare wire and tighten. Use caution to make sure no stray wire stands come in
contact with surrounding terminals causing short circuits. Run the wire directly to the
positive terminal of the car's battery. Make sure to use an in-line fuse within 12” of the
car's battery to protect the electrical system and amplifier against short circuits and/or
power surges.

Connect the ground terminal of the amplifier to the car's chassis.

For the ground connection, use an 4 to 8 gauge wire (black) to connect to the terminal
marked GND and then connect it to the car's chassis. Try to keep the length of the cable as
short as possible, preferably less than 6". Also make sure that the point on the car where
the connection is to be made is free of paint and dirt.

Connect the remote terminal of the amplifier to a switchable +12V source.

This connection allows the amplifier to be turned on and off with the power control of the
radio. If the radio has a REMOTE output terminal, connect it to the amplifier's terminal
marked REMOTE (using a 16 gauge wire or heavier). Now when the radio is turned on, the
amplifier will automatically turn on. This connection can also be made to the radio’s Power
Antenna wire.

7

SIGNAL CONNECTIONS

Connect the RCA output of the head unit (AM/FM cassette player, CD, or DAT) to the RCA
input terminals of the amplifier.

To make these connections, we recommend high quality RCA cables, which are available at
your local car audio retailer. 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). Please note that when making these connections the signal inputs correspond with
the speaker outputs.

SPEAKER CONNECTIONS (BRIDGED)

The BA amplifiers are capable of being bridged in a mono configuration. This feature allows
you the flexibility of using the amplifier to drive a ** subwoofer or a center channel. In
this configuration the amplifier sums the right and left channel to deliver one channel
(mono) output.

Please note: in order for the amplifier to sum right and left signal information, both right
and left RCA connections must be made.

**CAUTION! In the bridged mode, the amplifier must see the recommended minimum

impedance or higher. Any lower than the recommended minimum impedance will cause the
amplifier to overheat and possibly cause permanent damage to the amplifier!

SPEAKER CONNECTIONS (TRI-MODE)

The BA260, BA460, BA2100, BA2150HC, are capable of running in a Mono / Stereo mode. This
feature gives the amplifier the ability to run stereo satellites (midbass & tweeter)
simultaneously with a mono subwoofer.

These connections are more complicated because they require the use of passive
crossover networks (Not provided) to divide the frequencies to the speakers. We have
included a sample diagram for 4 Ohm connections. If you wish to use multiple speakers to
achieve a lower impedance and higher power, it is strongly recommended that you seek
professional advice from your BAZOOKA retailer before attempting to make these

ENGLISH

connections.

Please Note: In the Tri-mode configuration, the amplifier’s built-in crossover must be set to
the ”FLAT” position so the speakers receive full range output.

REMOTE BASS CONTROL MODULE (OPTIONAL)

Before connecting the remote, it will be necessary to find a mounting location that will be
easy to access for adjustment. Once you select your mounting location, you will need to
run the control wire from the remote to the amplifier. To avoid possibility of induced

noise from the car's electrical system (i.e. popping noises or engine noise), run the cable
from the remote to the amplifier away from the car's electrical wiring.

Please note: Once the remote is plugged in, it overrides the bass boost on the amplifier and
becomes the primary bass adjustment.

ADJUSTING THE X-OVER AND BASS

(Please note: If you intend to use the BA260, BA460, BA2100 AND BA2150 in the Tri-mode
configuration, it is necessary to set the crossover control to the “FLAT” setting in order to
receive full range output)

The “BA” amplifiers are equipped with a built-in crossover network allowing you to select
the crossover type (i.e. Low-Pass or Hi-Pass) and the desired crossover point. For example
if you wish to drive a pair of subwoofers, you can select the “Low Pass” setting on the
amplifier to filter out high frequencies. This will send only low frequencies to your
subwoofers (see example settings below).

not a volume control and you will not get more power out of the amplifier in the maximum
position! It may seem to deliver more output, but actually the system is only playing louder
faster as you turn the volume control on the radio. Ideally, to properly level match the
system the goal is to achieve maximum output from the amplifier without distortion at
about 3/4 of the volume control.

To determine if the amplifier’s gain is set properly, turn the system on and slowly increase
the volume control. You should be able to use about 3/4 volume before the system gets loud
but not distorting. It is very important when making these adjustments that you do not
over drive the speakers (at point of distortion) this will cause permanent damage to the
speakers. If you are unable to achieve 3/4 volume before distortion you will need to
adjust gain control (in this case you would reduce the gain). The gain controls should be
adjusted very slowly. It may help to have another person to assist you by adjusting the
gain controls while you listen for distortion.

The gain sensitivity control for the “BA”
amplifier is located on the side panel. This gain control
has been included to allow adjustment to properly
match the output of the radio. This is one of the most
misunderstood adjustments. By rotating the control in
the clockwise direction, the amplifier‘s input will
become more sensitive and the music will play louder. This is

TROUBLE SHOOTING THE SYSTEM

We have put together this trouble-shooting guide if you experience problems after
installing the amplifier. Please keep in mind that the majority of problems incurred are
caused by improper installation and not the equipment itself. In addition, there are many
components in the system that could cause various signal problems such as inducted
electrical noise and engine noise.

Before you can properly address the problem, you must first find the component that is
causing the problem. This will take patience and a process of elimination.
