Design Features
RUBI™(Rapid-Use Branched Impulse) This new proprietary power sup-
ply 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 frequen-
cies. Also, greater reserve gate power is stored for low voltage condi-
tions that occur during extreme conditions. чи
STACT M (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 in-
verted channels. Inthe STACT design, inversion is done at the power
amplifier drive stage. Since the fully symmetrical power amplifier pro-
duces no even-harmonic distortion itself and all preamplifier circuitry is
run completely in-phase, no even harmonic distortion phase reversal
OCCUrs.
Trident ™ 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 (> 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 (RUB300-2) Provides focused subwoofer
boost and routes wasted subsonic power to the audible bandwidth. |
The RUBICON RUB300-2 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 (RUB500-2 and RUB1000-2) Fully adjust-
able subwoofer equalization circuit providing frequency and boost (“Q”)
adjustment for optimum subwoofer performance. A frequency tracking
subsonic filterprotects woofers from potentially harmful low frequency
information and maximizes output in a usable range.
Harmonic Bass Alignmetn ™ The 2nd and 3rd order harmonic peaks
are critically aligned to fundamental peaks at low frequencies. This prc
duces tighter, more accurate bass reproduction. ЩИ
Drive Delay | ™ 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 (RUB500-2 and RUB1000-2) 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 Current ™ 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 be-
tween the circuit board and the heatsink to provide cool efficient ampli-
fier operation.
Fully Balanced 6-pin DIN Input (RUB500-2 and RUB1000-2) for pro-
fessional-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 Ba-
lanced Line Transmitters.
Continuously Variable Crossover Networks : 12 dB/Octave highpass
variable from 70 to 160 Hz, and 24 dB/Octave lowpass crossovers vari-
able from 55 to 220 Hz on (RUB500-2 and RUB10002).
12 dB/Octave highpassvariable from 50 to 200 Hz, and 24 dB/Octave
lowpass crossovers variable from 40 to 160 Hz on (RUB300-2).
Flexible Dual Input Level Control (RUB500-2 and RUB1000-2)
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, Bal-
anced Line, Speaker and Power wiring.

Crossover Adjustments
The RUBICONRUB300-2, RUB500-2 and RUB1000-2 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 lowpass portions of the crossover can be set independently of
one another.
To engage the High Pass filter on the Rubicon RUB500-2 and RUB1000
-2, 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 RubiconRUB300-2 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
A 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 RubiconRUB
500-2 and RUB1000-2, and 50 to 200 Hz on the RubiconRUB300-2, at 12
dB/Octave. The low pass crossover on the RubiconRUB500-2 and RUB
1000-2 is independently variable from 55 to 220 Hz and 40 to 160 Hz on the
RubiconRUB300-2 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 han-
dling, 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 bé severely
limited, |

Hawkins Bass Control-Theory and Use (RUB300-2)
Hawkins Bass Control (variable) is a unique subwoofer control circuit in-
cluded with the Soundstream RUBICON RUB300-2 amplifiers. It is capable
of removing subsonic energy in program material below 45 Hz
at 12 dB/Octave, while boosting subwoofer frequencies. The a
‘rcuit consists of two controls. One engages a subsonic Г |
“High Pass filter at 45 Hz, and the other adjusts the amount ond BAS о
of boost from 0 to +9dB.
The Boost control adjusts the amount of level applied at ae
the set frequency, and is adjustable from 0 to +9dB (see CONTROL
figure 2). When the boost is set to 0, Hawkins Bass Control O
acts as a sub sonic filter only. The simple act of removing 079
potentially harmful low frequencies can improve system -out q
put by as much as 3 dB LH

7.5 mm at 10 Hz. With Hawkins Bass Control properly adjusted, this excur-
sion can be reduced to less than 1 mm. This is of great benefit to lowering
woofer distortion and increasing output.

SELECTING THE SPEAKER OUTPUT MODE
The RUBICON RUB300-2 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 Modéw
the RCA inputs are automatically summed, so use both inputs.
The RUBICON RUB500-2 and RUB1000-2 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 contro! (for use with a singular mono input).

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:

characteristics.
2. No Interface module is
necessary.
3. Immune to noise radiated in the
car audio environment.
The RUBICON amplifiers’ signal inputs accept a wide range of input level: from
300 Vrms 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
~utput.
== 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. 1f you experience alternator wine or other instal-
lation 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

POWER AND GROUND
To ensure maximum output from your RUBICON amplifier, use high quality, low-
loss 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.

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 sup-
plied. 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-engineerew,,
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
a. Using the amplifier as a template, mark the holes on the mounting surface.
b. Remove the amplifier and drill the holes for the mounting screws.
c. Secure the amplifier to the mounting surface using the supplied hardware.
WIRING
a. Run and connect the audio signal and remote turn-on cables to the ampli-
fier from the source unit.
b. Carefully run the positive cable from the amplifier to a fuse or circuit breaker
within 18” of the battery.
c. Connect the fuse or circuit breaker lead to the battery. Leave the circuit
breaker off or the fuse out until everything is bolted down.
d. 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.
e. Double check each and every connection!
f. 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.
13
(INSTALLATION STEP 5 |
LEVEL SETTING
he input levels are adjusted by means of the input level controls located on the
(ont 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. Turn the amplifiers’ input levels to minimum position (counter-ciockwise)
2. Set the source unit volume to approximately 3/4 of full volume.
3... 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
( ec amplifier is reaching its maximum level, and has begun to clip (RUB500-2
nd RUB1000-2 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.
