Features
In the 80s, it became popular to use acronyms for amplifier features and technologies. In some cases, these acronyms
were nothing more than fancy words put together cleverly to form an acronym not worth its weight in poop! Sales people
memorized the silly acronyms but rarely knew what the feature encompassed. The features below are straight forward
facts about the amplifiers that make them yield audio nirvana.
General:
Full Signal Path Low Noise/Distortion Circuitry Topology
Optimal Component Layout for Minimal Distortion Induction & Signal Separation
Full Differential Feedback Surrounding Power-Amp Stages directly from Speaker Terminals resulting in Uncolored
Sound Reproduction and Elimination of Ground Loops
Differential Drives Divide Pre-Amp & Power-Amp Stages, Eliminating Ground Looping
Triple Darlington Audio Output Stages
Output Stage Bias Individually Sequenced, Optimizing Sound Quality
Close Tolerance Signal Path Components - 1% Resistors & 5% Capacitors
Stout 2 Oz. Copper Traces Effortlessly Transfer High Volume Internal Current
Differential RCA Inputs Isolate 12V/Audio to Ground, Eliminating Ground Loops and Noise
Sequenced Delays Eliminate Residual Power-Up/Power-Down Pops
Final PCB Layout Designs are a culmination of examination and fine tuning of all circuit elements to work in harmony
as a whole
Hawkins Boost Control - Proprietary Bass Equalization
Continuously Variable Crossovers
Tri-Mode Capable
