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.

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.

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

Chassisink™ All transistors are ideally located and sandwiched between the
circuit board and the heatsink to provide cool efficient amplifier operation.

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

Continuously Variable Crossover Network : 12dB/Octave highpass
crossover variable from 50 to 200 Hz and 24dB/Octave lowpass crossover
variable from 40 to 160 Hz.

Flexible Input Level Control allows 300 mV to 5 V input sensitivity.
Symmetrical Discrete Balanced Class A Drive Boards auto-adjust for linear

performance while driving low impedance loads.
