4STACTTM (STabilized Apex orrent _Topology) Reduces power supply stress by 50%. Typical designs degrade the stereo image due to phase reversal of
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
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 (‘KY’) 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.
4Harmonic 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.
4Drive Delay llTM Amplifier section powers up 2 to 3 seconds after the power supply eliminating

Fully Balanced
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 cool efficient ampli- fier operation.
Differentially Balanced RCA Input eliminates ground loop related noise in the audio.
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
Removable Front Spoiler allows for stealth installation of RCA, Bal- anced Line, Speaker and Power wiring.
SLEEPING BEAUTY
The Class A 5.2 aka SLEEPING BEAUTY is an amplifier like no other. It will produce l/4 of a watf x 2 at 4 ohms stereo but will deliver 500 watts into a 2, 1 or l/2 ohm mono load. We do not recommend running high impedance loads
