Bazooka CSA300.1, CSA50.4, CSA50.2, CSA200.3, CSA150.1 User Manual

Dear customer,

Congratulations on your purchase of a Bazooka CS 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 the CS high-performance series of amplifiers.
We hope that you will take as much pride in owning and using one of these high­quality audio products as we do designing and manufacturing them.

When properly installed and operated, your Bazooka CS 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 CS 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.

To ensure maximum power transfer and secure safe connections, it is recommended
to use high grade barrier spades (for connection at amplifier) 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.

Power Indicator

The diagnostic L.E.D. Illuminates green when the amplifier is on and receiving
power.

Tri Mode Capable (CSA50.2)

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 “CS”amplifiers include a built-in high and low pass crossovers. The crossover
features a fixed frequency @ 200 Hz for precise high or low pass filtering. **Except
CSA150.1 & CSA300.1 which has a variable 40 ~ 120Hz crossover.

Bass Boost (CSA150.1 & CSA300.1 Only)

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

Line Out (CSA150.1 & CSA300.1 Only)

One set of full range line outputs have been provided for convenient connection to
additional amplifiers in the system.

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.

Adjustable Input Sensitivity

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

Stable To 2 Ohm Stereo Mode

Stability to 2 ohm in stereo mode, 4 ohms bridged. The CSA150.1 & CSA300.1 are
stable to 2 ohms mono.

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.
