mpulse) 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.

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 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 (302) Provides focused subwoofer boost and
routes wasted subsonic power to the audible bandwidth. The RUBICON302
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 (502 and 1002) Fully adjustable subwoofer
equalization circuit providing frequency and boost (“Q”) adjustment for
optimum subwoofer performance. A frequency tracking subsonic filter
protects woofers from potentially harmful low frequency information and
maximizes output in a usable range.

♦ Harmonic Bass Alignment™ The 2nd and 3rd order harmonic peaks
are critically aligned to fundamental peaks at low frequencies. This pro-
duces tighter, more accurate bass reproduction.
