DESIGN FEATURES
RUBITM(_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.
STACTTM (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.
TridentTM Protection Topology 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 (>5 Volts) 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.
ChassisinkTM All transistors are ideally located and sandwiched between the circuit board and the heatsink to provide cool efficient amplifier operation.
Differentially Balance RCA Input eliminates ground loop related noise
in the audio.
Continuously Variable Crossover Networks: 12 dB/Octave 2-way
highpass variable from 65 to 220 Hz and 24 dB/Octave lowpass crossovers variable from 30 Hz to 120 Hz. 805 only - 12 dB/Octave 3-way
crossover which can be selected for mid-bass (65 to 500 Hz) or
.
midrange (65 to 4,000 Hz) operation.
Rear Channel De-Emphasis (805 only) A circuit based on theater
surround technology in which rear fill information is rolled off with a -3
dB point at 7,000 Hz following with a 6 dB/Octave slope to provide a
more realistic listening experience (in 5 channel mode only).
Flexible Dual Input Level Control allows 300 mV to 5 V input sensitivity.
Symmetrical Discrete Balanced Class A Drive Boards Auto-adjust for linear performance while driving low impedance loads.
Removable Front Spoiler allows for stealth installation of RCA, Balanced Line, Speaker and Power wiring.
Hawkins Bass Control provides a focused subwoofer boost (O-9 dB
at 45 Hz) and routes otherwise wasted amplifier power back to the
audible bandwidth.
Harmonic Bass Alignment TM The 2nd and 3rd order harmonic peaks
are critically aligned to fundamental peaks at low frequencies. This
produces tighter, more accurate bass reproduction.
Drive Delay IITM Amplifier section powers up 2 to 3 seconds after the
power supply eliminating turn-on pops. Turn off process is reversed:
Amplifier section turns off first, followed by the power supply.
Dynamically Optimized Power Grid TM Power grid is evenly distributed between primary and secondary power supplies, providing greater
dynamics and improved RF filtering.

CROSSOVER ADJUSTMENTS
The RUBICON amplifiers incorporate an on-board staggered electronic crossover, with RCA outputs to drive an external amplifier. No external electronic crossover is necessary. However, if you do desire to use an external crossover you still
have the option. The high and low pass portions of the crossover can be set
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 personal preference.
12 dB/Octave High Pass
2-WAY
39WAY (805 ONLY)
MIDBASS/MIDRANGE BAND PASS
The RUBICON can be operated in midrange or midbass “band pass” configuration. In the three way mode, you can tri-amplify with “active” midbass or
midrange to maximize control over individual drivers. The bandpass includes
a low pass and high pass filter, which work independent of one another, to
drive the midrange or midbass speakers.
Hawkins Bass Control - Theory and Use
Hawkins Bass Control (variable) is a unique subwoofer control circuit included with the Soundstream RUBICON & 805
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 dB).

CONTROL
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 a,cts 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.

Subwoofer drivers in general have excellent
power handling characteristics over their z
operational bandwidth. This bandwidth is de- dB.,0
termined by many factors, including driver -15
design and enclosure type. It is possible to -20
overdrive any subwoofer driver by sending I’,:

bandwidth. These potentially damaging signals 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 Hawkin’s

WIRING
SELECTING THE SPEAKER OUTPUT MODE
POWER AND GROUND
Channels 1 through 4 of the RUBICON & 805 amplifiers have the ability to
operate in any one of the following modes:
Stereo (STACT/Mxed Mono).= Use this mode for either stereo operation (left
and right channels) or for Mixed Mono operation.
Bridged Mono: Use this mode to get a bridged mono output while using only
the right channel input for 3 channel operation.
Please follow the wiring schemes below for the correct operation:
To ensure mlaximum output from your RUBICON amplifier, use high quality, lowloss power and ground cables and connections. The RUBICON amplifiers will
accept up to 4 gauge power and ground cables. Determine from the chart below
the minimum gauge power and ground wire for your application.

EXTERhlAL
Like all audio components, the RUBICON amplifier must be fused near the battery.
A fuse or circuit breaker must be located within 18” of the batters. 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 amplifier is fused with two automotive-type fuses and the
RUBJCON805 is fused with a single Maxi-Fuse. In the event of blown power supply fuses, 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!

LEVEL SETTING
INSTALLATION AND MOUNTING
AMPLIFIER LOCA T/ON
The RUBICON amplifier employs 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
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
a.
b.
C.
Using the amplifier as a template, mark the holes on the mounting surface.
Remove the amplifier and drill the holes for the mounting screws.
Secure the amplifier to the mounting surface using the supplied hardware.
INSTALLATION STEP 4 1
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 amplifier, follow these steps for
setting the input levels:
1.
2.
3.
Turn the amplifier’s 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.
WIRING
a.
b.
C.
d.
e.
f.
Run and connect the audio signal and remote turn-on cables to the amplifier
from the source unit.
Carefully Nn 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.
Once the amplifier is installed and the proper levels set, place the front spoiler in
position, and secure it using the supplied hardware.
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.
