SLA/SHTM
(Speaker Load Adapting I Subwoofer
Hyper-Efficient) This
new dual function technology currently operates in two different ways
in
different models. In subwoofer applications the power supply tracks the
incoming audio signal and increases or decreases its own voltage level
to mirror the input. This design results in enormous low impedance, low
frequency stability and maximum efficiency, since no power is wasted
maintaining an unnecessarily high voltage level in the power supply.
High Level Input with terminal block connector will accept a speaker
level input. This allows the user to hook this amplifier up to any factory
headunit.
Auto Turn On allows the amplifier to turn on without the use of a remote turn on wire, when the amplifier is using the high level inputs.
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 shutdown in extreme
thermal conditions.
Remote Wire Output provides a
+12
volt output to turn on another
amplifier.
Line Level Output
will allow the use of another Soundstream amplifier
to run the front speakers, while still retaining the factory head unit. This
option is only available when the high level inputs are used.
Hawkins Bass
ControlTM
provides a focused subwoofer boost
(O-6dB
at 45Hz) and routes otherwise wasted amplifier power back to the audible bandwidth.
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-on pops. Turn off process is reversed:
Amplifier section turns off first, followed by the power supply.
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 path.
Variable Crossover Network 12dB/octave low pass filter that is se-
lectable at 60, 80 or 1
OOHz.
Symmetrical Discrete Balanced Class A Drive Board auto-adjusts
for linear performance while driving low impedance loads.

RUBITM
Power Supply
(Rapid-Use Branched Impulse) Our new power
supply 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 now stored for low voltage conditions
that occur during extreme conditions.
+ STACTTM
(Stabilized Apex Current
lopology)
Reduces power supply
stress by 50%. Use of inverted channels usually degrades 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 preamp circuitry (which does produce even harmonics) is run completely in phase,
no even harmonic distortion phase reversal occurs.
+ TridentTM
Protection
Three types of protection for
RUBICON
amplifiers:
1.
Output protection against short circuits or improper loads.
2.
Ground fault detection shuts down the amplifier when a significant (5
volt or greater) voltage fluctuation occurs between audio ground and battery ground.
3.
Thermal protection will shut the amplifier down in extreme thermal
conditions.
+
Hawkins Bass Control
Provides focused subwoofer boost and routes
wasted subsonic power to the audible bandwidth. The A4 contains the
fixed Hawkins Bass Control which allows you to boost bass 6dB at
45Hz.
A built-in subsonic filter at 45Hz helps protect the speakers.

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.

Dynamically Optimized Power GridTM Power grid is now evenly dis-
tributed between primary and secondary power supplies, providing greater
dynamics and improved
RF
filtering.
