RUBITM(_Rapid-Be _Branched -Impulse) This new proprietary power sup- ply topology eliminates “powersags” 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.

4TridentTM 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 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 II TM 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 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.

ChassisinkTM All transistors are ideally located and sandwiched be- tween the circuit board and the heatsink to provide coo efficient ampli- fiea operation.

Differentially Balanced RCA Input eliminates grouid loop related

noise in the audio.

Fully Balanced 6-pin DIN Input for professional-quality performance and noise cancellation. The 6-pin DIN plug carries (*) signal informa- tion for Left and Right channels, audio ground, and * 15 Vdc to operate the Soundstream BLT / BLT4 Balanced Line Transmitters.

Continuously Variable Crossover Networks: 12 dB/Octave highpass variable from 70 to 160 Hz, and 24 dB/Octave lowpass crossovers vari- able from 55 to 220 Hz.

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 for linear performance while driving low impedance loads.

Removable Front Spoiler allows for stealth installation of RCA, Bal- anced Line, Speaker and Power wiring.
