Design Features
♦
RUBI™(Rapid-Use Branched Impulse) This new proprietary power supply topology eliminates “power sags” during low frequency reproduction
by rapidly increasing the duty cycle, stabilizing the power supply 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.
♦
STACT™ (STabilized Apex Current Topology) Reduces power supply
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.
♦
Trident ™ ProtectionTopology provides three types of protection:
1. Output protection against short circuits or improper loads.
2. Ground fault detection: Shuts down the amplifier when a significant
voltage (> 5Volts) fluctuation occurs between electrical (turn-on lead)
and battery ground.
3. Thermal Protection: Puts the amplifier into thermal rollback or shuts
the amplifier down in extreme thermal conditions.
♦
Hawkins Bass Control (302
) Provides focused subwoofer boost and
routes wasted subsonic power to the audible bandwidth. The RUBICON302
has the variable version of Hawkins Bass Control which allows you to
boost bass from 0 to 9dB at 45Hz. A built-in subsonic filter at 45Hz helps
protect the speakers.
♦
♦
Hawkins Bass Control (502 and 1002
) Fully adjustable subwoofer
equalization circuit providing frequency and boost (“Q”) adjustment for
optimum subwoofer performance. A frequency tracking subsonic filter
protects woofers from potentially harmful low frequency information and
maximizes output in a usable range.
Harmonic Bass Alignmen
t ™ The 2nd and 3rd order harmonic peaks
are critically aligned to fundamental peaks at low frequencies. This produces tighter, more accurate bass reproduction.
4
♦
Drive Delay I ™ Amplifier section powers up 2 to 3 seconds after the
power supply eliminating turn-on and off pops. The turn off process is
reversed: Amplifier section turns off first, followed by the power supply.
♦
Output Clipping Indicators (502 and 1002) indicate clipping on the
output stage of the amplifier. Monitoring the clipping indicators allows
the user to achieve maximum Sound Pressure Level without clipping
the amplifier.
♦
Auto High Curren
t ™ automatically matches the amplifier to the load
being driven allowing greater system flexibility, greater output, higher
reliability, and high efficiency 1 ohm (stereo) operation.
♦
Chassisink ™ All transistors are ideally located and sandwiched between the circuit board and the heatsink to provide cool efficient amplifier operation.
♦
Fully Balanced 6-pin DIN Input (502 and 1002) for professional-quality performance and noise cancellation. The 6-pin DIN plug carries (±)
signal information for Left and Right channels, audio ground, and ± 15
Vdc to operate the Soundstream BLT / BLT4 Balanced Line Transmitters.
♦
ContinuouslyVariable Crossover Networks : 12 dB/Octave highpass
variable from 70 to 160 Hz, and 24 dB/Octave lowpass crossovers variable from 55 to 220 Hz on (502 and 1002 ). 12 dB/Octave highpass
variable from 50 to 200 Hz, and 24 dB/Octave lowpass crossovers variable from 40 to 160 Hz on (302).
♦
♦
Flexible Dual Input Level Control (502 and 1002) allows 300 mV to
5 V input sensitivity. Separate Left and Right level controls allow user to
optimize system level control.
Removable Front Spoiler allows for stealth installation of RCA, Balanced Line, Speaker and Power wiring.

Crossover u
jdA stments
The RUBICON302, 502 and 1002 amplifiers incorporate an on-board
staggered electronic crossover, with RCA outputs to drive an external
amplifier. No external electronic crossover is necessary. The high and low
pass portions of the crossover can be set independently of one another.
To engage the High Pass filter on the Rubicon502 and 1002, set the left
crossover switch on the top of the amplifier to “H.P. X-OVER”, and use the
frequency adjustment knob marked “H.P. X-OVER”. To engage the Low Pass
filter, set the left crossover switch to either “SUB SONIC” or “HAWKINS
BASS CONTROL” (see pages 11-12 for more details), and set the right crossover switch “L.P. X-OVER” to the “IN” position.
On the Rubicon302 to engage full range operation set the crossover switch to
“AP.” To engage highpass or lowpass filtering set the crossover to “HP” or
“LP” and use the frequency adjustment dial labeled “X-OVER” to set the
frequency.
12 dB/Octave High Pass
24 dB/Octave Low Pass
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 70 to 160 Hz on the Rubicon502
and 1002, and 50 to 200 Hz on the Rubicon302, at 12 dB/Octave. The low
pass crossover on the Rubicon502 and 1002 is independently variable from
55 to 220 Hz and 40 to 160 Hz on the Rubicon302 at 24 dB/Octave.
For initial crossover setup, try setting the low pass filter to approximately 75
Hz, and the high pass filter to approximately 120 Hz. Change the crossover
points to accommodate a good mixture of frequency response, power handling, and personal preference.
IMPORTANT: Do not have the Low Pass filter and the High Pass
filter both engaged at the same time. While this won’t damage the
amplifier, the frequency range of the amplified signal will be severely
limited.

Hawkins Bass Control - Theory and Use (302)
Hawkins Bass Control (variable) is a unique subwoofer control circuit included with the Soundstream RUBICON amplifiers. It is capable of removing subsonic energy in program material below 45 Hz
at 12 dB/Octave, while boosting subwoofer frequencies. The
I IllIll
circuit consists of two controls. One engages a subsonic
HAWKINS
SUB
BASS
High Pass filter at 45 Hz, and the other adjusts the amount
SONIC
CONTROL
of boost from 0 to +9 dB.
l
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
acts as a sub sonic filter only. The simple act of removing
potentially harmful low frequencies can improve system output by as much as 3 dB.

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.

An easy method of optimizing your existing subwoofer enclosure with
Hawkin’s Bass Control is as follows:
1. Adjust the boost control to full
counter clock-wise (0) position.
2. Set the bass control switch to
“HAWKINS BASS CONTROL”.

Hawkins Bass Control (parametric) is a unique
subwoofer control circuit included with the
Soundstream RUBICON and 1002 amplifiers.
It is capable of removing subsonic energy in program material while boosting subwoofer frequencies. The circuit consists of two controls. One
adjusts the frequency of operation and the other
adjusts the range of boost. With both controls
adjusted fully counter-clockwise, no boost is applied and the amplifier is flat in response down to
20 Hz.

1.
Adjust frequency and boost control to full CCW position.
2.
Set the bass control switch to “HAWKINS BASS CONTROL”.
3.
While listening to music with strong bass content at a moderate level,
slowly adjust frequency control clockwise. Listen for a reduction of bass
response. Now, rotate frequency control slightly backwards. This serves
the purpose of removing the “subsonic” bass energy.
With Soundstream’s Hawkins Bass
Control, the boost and frequency control can provide virtually any combination of boost and cut to suit your designs. So, Hawkins Bass Control can
provide the “tailoring” needed for any
type of “assisted” design and any
woofer in any type of installation.

INSTALLATION STEP 1
SELECTING THE SPEAKER OUTPUT MODE
The RUBICON amplifier has the ability to operate in stereo, mixed mono, or
mono mode. For stereo or mixed mono operation switch the amp to stereo.
For bridged or mono applications switch the amplifier to mono. In mono mode
the RCA inputs are automatically summed, so use both inputs.
The RUBICON and 1002 amplifiers have the ability to operate in any one of
the following modes:
Stereo (STACT/Mixed Mono): Use this mode for either stereo operation (left
and right channels) or for Mixed Mono operation (stereo left and right channels
plus bridged mono for a subwoofer).
Summed Mono: Use this mode to get a bridged mono output while using both
the left and right inputs and gain controls.
Bridged Mono: Use this mode to get a bridged mono output while using only
the right channel input and gain control (for use with a singular mono input).

INSTALLATION STEP 2
BALANCED / UNBALANCED INPUT
The RUBICON502 and 1002 amplifiers have the ability to accept either a standard Unbalanced RCA signal input, or a Balanced “Pro Audio” style input signals
with the use of the Soundstream BLT Balanced Line Transmitter or some other
balanced line audio source. Before installing your system, you should decide
upon which signal type you wish to run. There are advantages to both:
BALANCED INPUT
UNBALANCED INPUT
ADVMAB
1. Most preamplifier / source
units have Unbalanced RCA
outputs (Industry Standard).
2. No Interface module is
necessary.
1. Improved Signal to Noise Ratio
(S/N Ratio).
2. Excellent noise cancellation
characteristics.
3. Immune to noise radiated in the
car audio environment.
The RUBICON amplifiers’ signal inputs accept a wide range of input level: from
300 mVrms to 5.0 Vrms for both Balanced and Unbalanced inputs. For the best
S/N Ratio, we recommend that the input level controls be set as far down as
possible (rotated counter-clockwise), while maintaining an acceptable level of
output.
Using the “Unbalanced” RCA Input
When using the Unbalanced RCA input, the R/GM channel input signal switch
MUST be in the “UNBAL” position. Also, when first installing the amplifier using
this input configuration, we suggest that the left channel input signal switch be in
the “UNBAL” position as well. If you experience alternator wine or other installation noise with both switches in the “UNBAL” position, try moving the LEFT
channel input signal switch to the “BAL” position. This should remove any
system noise due to the installation.
Using the “Balanced” RCA Input
When using the Balanced 6-pin DIN audio input, both switches MUST be in the
“BAL” position. Also, we recommend that when using this input configuration, the
input level controls be set to the “minimum” position (rotated counter-clockwise).
The system gain should then be adjusted on the Balanced Line Transmitter,
other balanced line audio source. For the pin configuration, see the diagram
below:

CIRCUIT BREAKERS AND FUSES
EXTERNAL
Like all audio components, the RUBICON amplifiers must be fused near the
battery. A fuse or circuit breaker must be located within 18” of the battery. This will
prevent a fire in the event of a shorted cable. See the chart below to determine the
correct fuse value.
INTERNAL
The RUBICON amplifiers are fused with an automotive-type or Maxi-fuse. In the
event of a blown power supply fuse(s), replace with the correct value fuse found in
the chart below. Never replace the fuse with a higher value than what is supplied. This may result in amplifier damage and will void the warranty!

INSTALLATION AND MOUNTING
AMPLIFIER LOCATION
The RUBICON amplifiers employ highly efficient circuitry, a custom-engineered
heat sink, and a unique Chassisink construction to maintain lower operating
temperatures. Additional cooling may be required if the amplifier is located in a
tightly confined 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

Run and connect the audio signal and remote turn-on cables to the amplifier from the source unit.
Carefully run the positive cable from the amplifier to a fuse or circuit breaker
within 18” of the battery.
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!
Re-connect the fuse or circuit breaker.
POWER UP
Power up the system, there may be a 2-3 second delay from the time the source
unit is turned on to the time that the amplifier turns on, which is normal. Once the
amplifier LED is on and the source unit is playing, you should have sound coming
from the speakers.
4
INSTALLATION STEP 5
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. For the RUBICON amplifiers,
follow these steps for setting the input levels:
1.
2.
3.
Turn the amplifiers’ input levels to minimum position (counter-clockwise)
Set the source unit volume to approximately 3/4 of full volume.
While playing dynamic source material, slowly increase the amplifiers’ input
level until a near maximum undistorted level is heard in the system.
The clipping indicators on the top of the amplifier let you know when the output of
the amplifier is reaching its maximum level, and has begun to clip (502 and 1002
only).
FRONT SPOILER
Once the amplifier is installed and the proper levels set, place the front spoiler in
position, and secure it on using the supplied hardware.

1. No power or ground at the amp.
2. No remote turn-on signal
3. Blown fuse near the battery
No sound, power LED is lit.
1. No signal input
2. The AIRBASS/Accessory switch
is in the “IN” position. Move it to the
“OUT’ position.
Repeatedly blow amp fuse;
frequent activation of Smart Power
Supply Circuit
1. Speaker or leads may be shorted
2. Verify adequate amp ventilation
Not enough input sensitivity while
using the Balanced Input
Be sure both Left and Right input
signal switches are set to the "BAL"
position.
Very little output, or output is
muffled.
Make sure that both the L.P. and
the H.P. crossovers aren't
engaged
Left and Right “Clip” indicators
ighting
Output signal level is too high and
the amplifier output is clipping.
Reduce the level either at the source
or at the input level controls.
Alternator whine while using
Unbalanced RCA inputs
1. Make sure the Right Input Signal
Switch is in the "UNBAL" position.
2. Try the Left Input Signal switch
in the "BAL" and "UNBAL" position:
leave the switch in the quietest
setting. This will not effect the
performance of the amplifier.
