AudioControl A1500.1 amplifier

AudioControl A1500.1 Amplifier

AudioControl presents a 1-channel amplifier from the Altitude series, designed from the ground up with an emphasis on a modern and minimalist appearance. The elegant anodized aluminum chassis in matte gray provides effective heat dissipation. Altitude models feature Valet Mode, which protects the audio system from unintended damage by limiting maximum volume to 25% when activated. They are also compatible with start-stop systems and electric vehicles, ensuring top performance in any car. Altitude series amplifiers deliver high power in a compact package and class-leading sound quality. ParaBASS controls allow precise tuning of the bass response to your preferences. Take control of your sound and enjoy the bass exactly how you like it.

The power circuitry uses advanced pulse-width modulation integrated circuits that provide increased power and efficiency. The HEXFET® Power MOSFET transistors from International Rectifier are engineered for extremely low on-resistance and reliable high-speed switching. A premium toroidal transformer ensures optimal efficiency and minimal signal distortion. Low-ESR capacitors contribute to minimal losses and reduced heat. Precision metal potentiometers provide accurate adjustment and durable construction. The amplifier uses X2 class (500 V) capacitors with self-healing properties for high-frequency protection and MOSFET protection. Output filters with ferrite cores ensure high efficiency and minimal losses. A powerful intelligent Class D driver IC with PWM modulation and protection, together with HEXFET® MOSFETs, delivers ample power and high efficiency.

About AudioControl

As the name suggests, AudioControl has been all about controlling sound for more than 40 years. Especially in the United States, AudioControl is a respected and popular manufacturer of both car and home audio equipment. The company’s headquarters—including research, development, manufacturing, and training facilities—thrives in Mountlake Terrace, Washington, in the heart of the Pacific Northwest. All products are still designed and proudly made in the USA, ensuring high quality and reliability. This is reflected in the five-year warranty AudioControl offers on its products. AudioControl engineers are responsible for several patented technologies that have created new ways to improve vehicle audio systems, and that innovation remains the company’s focus. The product range is relatively narrow, specializing in premium digital amplifiers, DSP processors, equalizers, preamplifiers, and products for integrating new sound systems into existing factory units. Professional measurement tools are also available to help achieve AudioControl’s main goal, perfectly captured by their slogan "Making good sound great".
