yper-Efficient) This
new dual function technology currently operates in two different ways in
different models. In subwoofer applications the power supply tracks the
incoming audio signal and increases or decreases its own voltage level
to mirror the input. This design results in enormous low impedance, low
frequency stability and maximum efficiency, since no power is wasted
maintaining an unnecessarily high voltage level in the power supply.

opology) 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.

¨ Trident™ 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 (> 5Volts) 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-on and off pops. The turn off process is
reversed: Amplifier section turns off first, followed by the power supply.
