RUBITM(_Rapid-Be _Branched -Impulse)
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 low frequen­cies. Also, greater reserve gate power is stored for low voltage condi­tions that occur during extreme conditions.
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.
STACTTM (STabilized
Apex
orrent _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.
Hawkins Bass Control - Fully adjustable subwoofer equalizaton circuit
providing frequency and boost (“Q”) 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
The 2nd and 3rd order harmonic peaks are critically aligned to fundamental peaks at low frequencies. This produces tighter, more accurate bass reproduction.
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.
