RUBITM(_Rapid-Be

_Branched

-Impulse)

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.

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 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.

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

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.

Drive Delay II

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.

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

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.

ChassisinkTM

All transistors are ideally located and sandwiched be-

tween the circuit board and the heatsink to provide coo

fiea operation.

Differentially Balanced RCA Input eliminates grou
