We faced the daunting task of improving our now legendary ASA-Series amplifiers. Welcome ASA3! Our third generation of ASA-Series amplifiers have a narrower footprint for installation versatility, increased overvoltage protection, broader input sensitivity, new extruded chassis designed for better heat management and a sporty light-up badge. We still managed to keep all the popular features usually found only in other brands' high-end ranges. Feature-packed with a wide line-up of 2-, 4- and even 5-channel amplifiers, ASA3 Amplifiers meet the needs of any serious audiophile. The new, improved heatsink uses more extruded fins, while still maintaining the clean lines that made ASA a classic. These amplifiers always deliver pure, clean power with the soul of rock and roll or whatever your taste. They feature variable 12 dB, high-/low-pass electronic crossover for infinite system applications.
