They handle power without blowing their cool
High-speed MOSFET switching power supply offer fast response and high efficiency, plus generate very little heat. High current Bipolar Output Transistors pump maximum voltage and high current to your speakers or subwoofers.

Yes, circuit board design is important. Very important.
Double Layer Fiberglass Epoxy Printed Circuit Boards for more rigidity and less shrinkage, with plated through-holes instead of jumpers, for twice the amount of component contact area. Efficient layout packs more circuitry, with tighter component tolerances, into a smaller circuit board for a smaller overall amp footprint.

Let's talk about protection
This much power has to be kept under "lock and key," protected, and cut loose only under the right kind of supervision. So PA Amps have comprehensive, cover-your-butt 6-Way Smart System Protection (SSP) Circuits. Every amp includes Power and Ground-Reversal Protection, Thermal and Short Protection, Current Overdraw and Low Impedance Protection circuits with Auto-Standby Mode. It's all about safety, reliability and durability.

Built like a brick outhouse, but with anodized extruded-aluminum
PA Amps are armored with anodized, extruded brushed-aluminum covers and bullet-proof end caps that also act as thermal sinks to provide maximum heat dissipation. The end caps also hide connectors for a clean, minimalist look. Even the logo is solid aluminum, and the model panel is back lit in cobalt blue.

In polite circles it's called functionality, but it's really about kick-butt performance
Selectable 12 dB/octave high or low-pass crossover with fixed crossover frequency; can be defeated for full range (flat) operation. Monoblocks feature an adjustable 12 dB/octave low-pass crossover (30-250 Hz). All PA amps give you a switchable 8 dB bass boost at 40Hz for some extra bad boy thumping.
