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
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.
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. In the STACT design, inversion is done at the power
amplifier drive stage. Since the fully symmetrical
duces no even-harmonic distortion itself and all preamplifier circuitry is
run completely in-phase, no even harmonic distortion phase reversal
occurs.
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 Alignment TM 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 informa-

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 distrib-
uted 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.

Differentially Balanced RCA Input eliminates ground loop related
noise in the audio.
Flexible Dual Input Level Control allows 300 mV to 5 V input sen-
sitivity. Separate Left and Right level controls allow user to optimize
system level control.
Symmetrical Discrete Balanced Class A Drive Boards Auto-adjust

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.
