AudioControl A800.1 amplifier

AudioControl A800.1 Amplifier

AudioControl introduces a 1‑channel amplifier from the Altitude series, engineered from the ground up with a focus on modern, minimalist styling. The elegant anodized aluminum chassis in matte gray ensures efficient heat dissipation. Altitude models feature Valet Mode, which protects your system by limiting maximum volume to 25% when activated. They are also compatible with start‑stop systems and electric vehicles, delivering top performance in any car. Altitude amplifiers offer high power in a compact package and class‑leading sound quality. ParaBASS controls let you precisely shape the bass response to your preference — take control of your sound and enjoy bass exactly the way you like it.

Power circuitry uses advanced pulse‑width modulated integrated circuits for greater power and efficiency. HEXFET® Power MOSFET transistors from International Rectifier are chosen for extremely low on‑resistance and reliable high‑speed switching. A premium toroidal transformer ensures optimal efficiency and minimal signal distortion. Low‑ESR capacitors reduce losses and heat. Precision metal potentiometers provide accurate adjustment and robust construction. The amplifier uses Class X2 (500 V) self‑healing capacitors for high‑frequency protection and MOSFET safeguarding. Output filters with ferrite cores deliver high efficiency and minimal losses. A powerful intelligent Class D driver IC with PWM modulation and protection, together with HEXFET® MOSFETs, supplies ample power with high efficiency.
