Ultra Low-Impedance Output Capablility: The RUBICONI 0.2 and
5.2 are designed for optimal performance into loads as low as l/2 or
l/4 ohm stereo (1 or I/2 ohm mono).

RUBITM(_Rapid-&e Banched _/mpulse) 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 orrent _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 (> Welts) 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 - Fully adjustable subwoofer equalizaton circuit
providing frequency and boost (‘KY’) adjustment for optimum subwoofer
performance. A frequency tracking subsonic filter protects woofers from
potentially harmfull low frequency information and maximizes output in
a usable range.
Harmonic Bass AlignmentTM 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 llTM Amplifier section powers up 2 to 3 seconds after the
power supply eliminating turn-oncand off pops. The turn off process is
reversed: Amplifier section turns off first, followed by the power supply.

Fully Balanced 6-pin DIN Input for professional-quality performance
and noise cancellation. The 6-pin DIN plug carries (*) signal information for Left and Rlight channels, audio ground, and * 15 Vdc to operate
the Soundstream BLT / BLT4 Balanced Line Transmitters and Balanced X.0 crossovers.
Output Clipping Indicators 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.
Dynamically Optimized Power Grid TM . Power grid is evenly distributed between primary and secondary power supplies, providing greater
dynamics and improved RF filtering.
Auto High CurrentTM automatically matches the amplifier to the load
being driven allowing greater system flexibility, greater output, higher
reliability, and high efficiency 1 ohm (stereo) operation.
ChassisinkTM All transistors are ideally located and sandwiched between the circuit board and the heatsink to provide cool efficient amplifier operation.
Differentially Balanced RCA Input eliminates ground loop related
noise in the audio.
Flexible Dual Input Level Control allows 300 mV to 5 V input sensitivity. Separate Left and Right level controls allow user to optimize
system level control.
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.
SLEEPING BEAUTY
The Class A 5.2 aka SLEEPING BEAUTY is an amplifier like no
other. It will produce l/4 of a watf x 2 at 4 ohms stereo but will
deliver 500 watts into a 2, 1 or l/2 ohm mono load. We do not
recommend running high impedance loads (3-4 ohm stereo) since
the output will be minimal.

Hawkins Bass Control - Theorv and Use
Hawkins Bass Control (parametric) is a unique
subwoofer control circuit included with the
Soundstream RUBICON Class A 10.2 and 5.2 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.

bandwidth. These potentially damaging signals can be removed by adding a subsonic filter. Figure 5 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.

the starting point of the subsonic fil0

and 5.2, the high pass filter has two dB +
frequency ranges. When the bass 1::

the high pass filter frequency can be adjusted from 13 Hz up to a maxi- ‘3010I
mum of 30 Hz. In this setting, no
boost “Q” control is available. This
control is useful for setting the lowest frequency that your subwoofer will
see (see figure 1). When the bass dB
control switch is set to “HAWKINS
BASS CONTROL”, the high pass filter frequency can be adjusted from
30 Hz to a maximum of 70 Hz. In
this setting, there is an available!
boost control of 0 to +9 dB.

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.

An easy method of optimizing your existing subwoofer enclosure with
Hawkin’s “Hz” control is as follows.
With Soundstream’s Hawkins Bass

SELECTING THE SPEAKER OUTPUT MODE
The RUBICON Class A 10.2 and
any one of the following modes:
5.2 amplifiers have the ability to operate in
Stereo (STACT/Mjx& 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).
The RUBICON Class A 10.2 and 5.2 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:
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).

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 RIGHT 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 vou exDerience alternator wine or other installation noise with both switches in the “UNBAL” position, try movina the LEFT
channel inout signal switch to the “BAL” Dosition. 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

The system gain should then be. adjusted on the BLT Balanced Line Transmitter,
other other balanced line audio source. For the pin configuration, see the diagram below:

WIRING
POWER AND GROUND
To ensure maximum 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.

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.
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.

INSTALLATION STEP 5
TRIDENT PROTECTION CIRCUITRY
Your Rubicon amplifier is protected against both overheating and short circuits
by means of main power fuses and the following circuits:
*
Auto High Current power supply
+
Speaker Output Protection
+ Ground Fault Differential
The input levels are adjusted by means of the individual channel 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.

Smart Power Supply Thermal Rollback and a Thermal Protection Circuit
T NOTE: If you experience blown main power supply fuses, it is like9
thaf the amplifier is seeing a dead short, either in the speaker wire or in
the speaker itself. Rectijl the problem before blowing multiple fuses!
DO NOT increase values beyond the original fuse value1 Doing so will
void your warrant and may damage your amplifer.
