RUBITM(/Japid-_Use Branched !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 wide band frequencies. Also, greater reserve gate power
is stored for low voltage conditions that occur during extreme conditions.
STACTTM (STabilized Apex
Topology)
Reduces power
- Current
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.
Fully Balanced Inputs for professional-quality performance and
noise cancellation. The 6-pin DIN plug carries (k) signal information
for Left and Right channels, audio ground, and * 15 Vdc to operate
the Soundstream BLT / BLT4 Balanced Line Transmitters.
Harmonic Bass AlignmentTM The 2nd and 3rd order harmonic peaks
are critically aligned to fundamental peaks at mid and low frequencies. This produces tighter, more accurate bass reproduction.
Drive Delay II TM 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.
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.
4
Dynamically Optimized Power GridTM Power grid is evenly
distributed between primary and secondary power supplies, providing greater dynamics and improved RF filtering.
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.
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 Autoadjust for linear performance while driving low impedance loads.
Removable Front Spoiler Allows for stealth installation of RCA,
Balanced Line, Speaker and Power wiring.

[ INSTALLATION STEP 2
The RUBICON Class A [email protected] and RWOIR amplifiers have the ability to operate in
any one of the following modes:
The RUBICON Class A PlclclSS0 and EIUOIR 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:
Stereo (STACT/Mxed Mono): Use this mode for either stereo operation (left
and right channels) or for Mixed Mono operation (stereo left and rigIht channels
plus bridged mono).
I
*
Brr’dged 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).
UNBALANCED tNPUl
Please follow the wiring schemes below for the correct operation:
ADVANTAGES
-
L+
-
1. Most preamplifier /
source units have
Unbalanced RCA outputs
(Industry Standard).
2. No Interface module is
necessary.
BALANCED INFUT
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 RIGHTchannel (channel 2) input
signal switch MUSTbe 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
whine or other installation noise with both switches in the “UNBAL” r>osition,
trv movincl the LEFTchannel input sianal switch to the “BAL” Dosition. This
should remove any system noise due to the installation.
U&g the “Balanced” DIN Input
When using the Balanced 6-pin DIN audio input, both switches MUSTbe in the
“BAL” position. Also, we recommend that when using this input configuration,
the input level controls be set to the “minimum” position (rotated counterclockwise). The system gain should then be adjusted on the BLT Balanced
Line Transmitter, other other balanced line audio source. For the pin configura-

REMOTE TURN-ON
Connect the “Remote” line to the turn-on lead from the source unit. When +12
Volts is received, the amplifier will turn on.
SIGNAL CABLE
Use a high quality cable that will be easy to install and has minimal signal loss to
guarantee optimum performance.
POWER AND GROUND
To ensure maximum output from your RUBICON Class A amplifier, use high
quality, low-loss power and ground cables and connections. The RUBICON
Class A 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 Class A amplifiers must be fused near
the battery. A fuse or circuit breaker must be located within 18” of the batterv.
This will prevent a fire in the even of a shorted cable. See the chart below to
determine the correct fuse value.

INTERNAL
The RUBICON Class A amplifiers are fused with an automotive-type fuse. In the
even of a blown power supply fuse, 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 warranfy!

INSTALLATION STEP 4 )
AMPLIFIER LOCATION
The RUBICON Class A amplifiers employ highly efficient circuitry, a customengineered 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.

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 5
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
Class A 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.

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 connection1
Re-connect the fuse or circuit breaker.
Once the amplifier is installed and the proper levels set, place the front spoiler in
position, and bolt it on 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.
