new dual function technology currently operates in two different ways
different models. In subwoofer applications the power supply tracks the
incoming audio signal and increases or decreases its own voltage level
to mirror the input. This design results in enormous low impedance, low
frequency stability and maximum efficiency, since no power is wasted
maintaining an unnecessarily high voltage level in the power supply.

ANGINA CROSSOVER
The ANGINA is designed as a mono subwoofer amplifier. This means the
amplifier will direct 200 watts of pure hard-core bass to your subwoofers. It
handles these low frequencies with a Butterworth,
filter.
These low pass frequencies are directed by the three position switch which
sits on top of the amplifier as shown in the shaded area below. The switch
selects from the following three frequencies; 60, 80 or 1

This bandwidth is deter-
mined by many factors, including driver design, and
enclosure type. It is possible
to overdrive any subwoofer
driver by sending powerful
signals outside of its operational bandwidth. These potentially damaging sig-
nals can be removed by adding a subsonic filter. Figure 1 shows the effective-
ness of the Hawkins Bass Control on woofer excursion in a vented enclosure. The woofer travels
erly adjusted, this excursion can be reduced to less than 1 mm. This is
great benefit to lowering woofer distortion and increasing output.
With Soundstream’s Hawkins Bass Control, the boost and frequency control can provide the “tailoring” needed for any type of “assisted” design and
any woofer in any type of installation.

When mounting the amplifier, it should be securely mounted to either a panel in the
vehicle or an amp board or rack that is securely mounted to the vehicle. The
mounting location should be either in the passenger compartment or in the trunk of
the vehicle, away from moisture, stray or moving objects, and major electrical components. To provide adequate ventilation, mount the amplifier so that there are at
least two inches of freely circulating air above and to the sides of it.
MOUNTING THE AMPLIFIER
Using the amplifier as a template, mark the holes on the mounting surface.

Remove the amplifier and drill the holes for the mounting screws.

Connect the fuse or circuit breaker lead to the battery. Leave the circuit
breaker off or the fuse out until everything is bolted down.

Secure the ground cable to a solid chassis ground on the vehicle. It may be
necessary to sand paint down to raw metal for a good connection.
Double check each and every connection!

you should have sound coming from the speakers.

Level
The input levels are adjusted by means of the input level controls located on the
front of the amplifier as shown below in the shaded area. This is a unique
~
stage circuit that adjusts both level and gain. This topology maintains better S/N
Ratio even when using sources with minimal output.
In the ideal situation, all components in the audio system reach maximum undistorted
output at the same time. If you send a distorted signal to an amplifier, it is simply
going to amplify distorted information. The same holds true if an outboard pro-
Setting
dual-
cessor or crossover begins to distort before you have maximum output from the
amplifier. By setting all components to reach clipping at the same time, you can
maximize the output of your system. For the
