DESIGN FEATURES

SLA/SH™(Speaker Load Adapting/ Subwoofer Hyper-Efficient) This new dual
function technology currently operates in two different ways in different models.
In full bandwidth applications the power supply adapts itself to the impedance
of the connected speaker load by continuously varying the internal supply
voltage, assuring maximum power output.
This design improves efficiency and allows for a greater level of installation
flexibility. In subwoofer applications the power supply tracks the incoming
audio signal and increases of 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.
BIO™Port(Bridging In and Out) Enables two identical mono amplifiers
channels to be fused together into a single subwoofer load with double the
output power.
STACT™ (STabilized Apex Current 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 inverted channels. In
the STACT design, inversion is done at the power amplifier drive stage. Since
the fully symmetrical power amplifier produces 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
(>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 - Fully adjustable subwoofer equalization circuit
providing frequency and boost("Q")adjustment for optimum subwoofer
performance. A frequency tracking subsonic filter protects woofers from
potentially harmful low frequency information and maximizes output in a usable
range.
