Over the years, home theater amplifiers have achieved strong performance, but often with a focus on power parameters at the expense of sound quality. Starke Sound's “A Series” are designed with a compre- hensive objective in mind: high-power, multi-channel amplifiers with perfect sound quality. The new, 3-channel, A3 model applies Starke Sound's unique Class A+AB power amplifier design (3rd generation), with an output of up to 620 watts per channel at 4Ω, a fully balanced topology, and a power supply capacitor array delivering up to 80,000 microfarads. It is an extremely high bias design that main- tains Class A operation for music or audio signals in most applications. With very large signals, typically 1% of content, A3 enters Class AB to completely ensure that the dynamics of the system are not compressed. In other words, this is a pure Class A amplifier with high power reserves. An aluminum alloy and copper hybrid heat dissipation system eliminates the need for fans, ensuring silent operation and higher-quality audio output. The center channel of A3 has an input switch. When you turn off this switch, A3 becomes a pure 2-channel amplifier with proportionally higher power supply reserves. A3's ultra-low distortion, abundant energy, and flexibility make it ideal to serve as the core driving force behind private theaters and Hi-Fi systems.
