AudioControl A600.4 amplifier

AudioControl A600.4 Amplifier

AudioControl introduces a four-channel amplifier from the Altitude series, designed from the ground up with an emphasis on a modern and minimalist look. The elegant anodized aluminum chassis in matte gray provides effective heat dissipation. Altitude models are equipped with Valet Mode, which protects the sound system from accidental 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 amplifiers deliver high power in a compact body and class-leading sound quality.

Power circuits use advanced integrated PWM circuits that provide higher power and efficiency. The HEXFET Power MOSFET transistors from International Rectifier are designed for extremely low on-resistance in the on state and reliable high-speed switching capability. A premium toroidal transformer ensures optimal efficiency and minimal signal distortion. Low-ESR capacitors contribute to minimal losses and reduced heating. Precision metal potentiometers allow precise adjustment and durable construction. The amplifier uses X2 class capacitors (500 V) 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 modulator and protection, together with HEXFET MOSFET transistors, 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 very popular manufacturer not only of car audio but also home audio. The company's headquarters, including research, development, manufacturing and training facilities, thrive in Mountlake Terrace, Washington, in the heart of the Pacific Northwest temperate rainforest. All products are still designed and proudly manufactured in the USA, which guarantees their high quality and reliability. This is also reflected in the five-year warranty that AudioControl provides on its products. AudioControl engineers are behind several patented technologies that created new ways to improve automotive audio. That is precisely the company's focus. The product range is relatively narrow, specializing in high-end digital amplifiers, DSP processors, equalizers, preamplifiers and, above all, a range of products for integrating a new sound system into existing factory units. Professional measurement tools are also available, helping to fulfill AudioControl's main goal, perfectly captured by their slogan "Making good sound great".
