DESIGN FEATURES
RUBITM(_Rapid-Use
supply topology eliminates “power sags” during low frequency reproduction by rapidly increasing the duty cycle, stabilizing the power sup-
ply and allowing it to deliver the power required when reproducing low
frequencies. Also, greater reserve gate power is stored for low voltage conditions that occur during extreme conditions.
STACTTM (STabilized
ply stress by 50%. Typical designs degrade the stereo image due to
phase reversal of even-order harmonic distortion that occurs between
the inverted channels. In the STACT design, inversion is done at the
power amplifier drive stage. Since the fully symmetrical power amplifier produces no even-harmonic distortion itself and all preamplifier
circuitry is run completely in-phase, no even harmonic distortion phase
reversal occurs.

independently of one another.
In many car audio installations, there is a tendency for a “midbass boom.” Because of their interior dimensions, most cars will resonate or ring at these midbass
frequencies. If we design the system so there is reduced output in this region, the
final response is very smooth and natural sounding. The high pass crossover is
independently variable from 65 to 220 Hz at 12 dB/Octave, and the low pass
crossover is independently variable from 30 to 120 Hz at 24 dB/Octave.
For initial crossover setup, try setting the low pass filter to approximately 60 Hz,
and the high pass filter to approximately 100 Hz. Change the crossover points to
accommodate a good mixture of frequency response, power handling, and per-
sonal preference.

Hawkins Bass Control - Theory and Use
Hawkins Bass Control (variable) is a unique subwoofer control circuit included with the Soundstream
amplifiers. It is capable of removing subsonic energy in program material below 45 Hz at 12 dB/Octave, while boosting
subwoofer frequencies. The circuit consists of two controls. One
engages a subsonic High Pass filter at 45 Hz, and the other
adjusts the amount of boost (0 to +9
The Boost control adjusts the amount of level applied at the
set frequency, and is adjustable from 0 to +9 dB (see figure 2).
When the boost is set to 0, Hawkins Bass Control
sonic filter only. The simple act of removing potentially harmful
low frequencies can improve system output by as much as 3
dB.
Application
Subwoofer drivers in general have excellent
power handling characteristics over their
operational bandwidth. This bandwidth is determined 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
nals can be removed by adding a subsonic filter. Figure 3 shows the effectiveness
of the Hawkins Bass Control on woofer excursion in a vented enclosure. The
woofer travels 7.5 mm at 10 Hz. With Hawkins Bass Control properly adjusted, this
excursion can be reduced to less than 1 mm. This is of great benefit to lowering
woofer distortion and increasing output.
Adjustment
An easy method of optimizing your existing subwoofer enclosure with
Bass Control is as follows:
1.
Adjust the boost control to full counter
clock-wise (0) position.
2. Set the bass control switch
“HAWKINS BASS CONTROL”.
3. Play moderate to loud bass material.
4.
Adjust the boost (Q) control until you
reach the desired level.

confied
area or when driving especially low impedance loads at extremely high
levels.
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.

LEVEL SETTING
The input levels are adjusted by means of the input level controls located on the
front of the amplifier. This is a unique dual-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 processor 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.
setting the input levels:
1.
Turn
the amplifier’s input levels to minimum position (counter-clockwise)
2.
Set the source unit volume to approximately
3.
While playing dynamic source material, slowly increase the amplifiers’ input
level until a near maximum undistorted level is heard in the system.
Once the amplifier is installed and the proper levels set, place the front spoiler in
position, and secure it using the supplied hardware.
For the
RUBICON
amplifier, follow these steps for
3/4
of full volume.
POWER UP
Power up the system and look at the Power LED; there may be a 2-3 second delay
from the time the source unit is turned on to the time that the LED on the amp turns
on, which is normal. Once the amplifer LED is on and the source unit is playing,
you should have sound coming from the speakers.
