DESIGN FEATURES

RUBITM(_Rapid-Use Branched Impulse) This new proprietary power supply topology eliminates “power sags” duringlow frequency repro- duction by rapidly increasing the duty cycle, stabilizing the power sup- ply and allowing it to deliver the power required when reproducing low frequencies. Also, greater reserve gate power is stored for low volt- age conditions that occur during extreme conditions.

STACTTM (STabilized Apex current _Topology) Reduces power sup- ply 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 ampli- fier 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 (>5 Volts) 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 provides a focused subwoofer boost (O-9 dB at 45 Hz) and routes otherwise wasted amplifier power back to the audible bandwidth.

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 IITM Amplifier section powers up 2 to 3 seconds after the power supply eliminating turn-on pops. Turn off process is reversed: Amplifier section turns off first, followed by the power supply.

Dynamically Optimized Power Grid TM Power grid is evenly distrib- uted between primary and secondary power supplies, providing greater dynamics and improved RF filtering.

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

Differentially Balance RCA Input eliminates ground loop related noise in the audio.

Continuously Variable Crossover Networks: 12 dB/Octave 2-way highpass variable from 65 to 220 Hz and 24 dB/Octave lowpass cross- overs variable from 30 Hz to 120 Hz. 805 only - 12 dB/Octave 3-way crossover which can be selected for mid-bass (65 to 500 Hz) or

midrange (65 to 4,000

Hz) operation.

Rear Channel De-Emphasis (805 only) A circuit based on theater surround technology in which rear fill information is rolled off with a -3 dB point at 7,000 Hz following with a 6 dB/Octave slope to provide a more realistic listening experience (in 5 channel mode only).

Flexible Dual Input Level Control allows 300 mV to 5 V input sensi-

tivity.

Symmetrical Discrete Balanced Class A Drive Boards Auto-ad- just for linear performance while driving low impedance loads.

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