Owner’s Manual

and

Installation Guide

Congratulations!

You now own the Soundstream

RUBICON

Class A amplifier, the most musi-

cal amplifiers ever created for the

12

volt environment. Your Soundstream

RUBICON

IWKSO

and

ENOR

Class A amplifiers are critically engineered to
reproduce the most subtle details of high-pass and full-range applications
and will outperform any other amplifier in the world.

To maximize the performance of your system, we recommend that you thor­oughly acquaint yourself with its

capabilites

and features. Please retain this

manual and your sales receipt for future reference.
Soundstream amplifiers are the result of American craftsmanship and thf

highest quality control standards. When properly installed, they will providt

you with many years of listening pleasure. Should your amplifier ever need

service or replacement due to theft, please record the following information

which will help protect your investment.

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 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 (>

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 Alignment

TM

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.

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

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.
