AT522NC Power Amplifier: Unleash the Power of High-Fidelity Audio

Designed and manufactured by Amplifier Technologies Inc (ATI), this amplifier is a powerhouse that delivers exceptional performance, build quality, and utility. Whether you’re a music enthusiast or a home theater connoisseur, the ATI AT522NC is the perfect choice to elevate your audio experience.

Elegant and Functional Design

The ATI AT522NC amplifier features a sleek, modern design that seamlessly integrates into any audio setup. With its flat aluminum faceplate, elegant capacitive touch power button, and backlit ATI logo, this amplifier exudes sophistication. The amplifier also includes handles and 5-way binding posts for easy installation and connectivity. The AT522NC’s design not only enhances its aesthetic appeal but also reflects ATI’s commitment to delivering top-tier performance.

Uncompromising Performance

The ATI AT522NC amplifier is a Class D amplifier that utilizes Hypex N-Core technology, ensuring exceptional sound quality and efficiency. With 200W per channel into 8Ω and 300W per channel into 4 ohms, this amplifier delivers powerful and dynamic audio reproduction. The amplifier’s low distortion (<0.05%) and high signal-to-noise ratio (>120dB) ensure that you hear every detail of your favorite music or movie soundtrack with maximum clarity and precision.

Smart Features

ATI has incorporated intelligent features into the AT522NC amplifier to enhance user experience and optimize performance. The amplifier uses microprocessor control for turn-on delay, automatic AC power recognition, and configuration. This means the amplifier can automatically adjust its settings based on the power supply voltage, ensuring optimal performance and protection. Additionally, the amplifier includes a “sleep” circuit that conserves energy when no input signal is detected for a period of time. This feature not only reduces power consumption but also ensures instant playback when a signal is detected.

Versatile Connectivity Options

The ATI AT522NC amplifier offers flexible connectivity options to accommodate various audio setups. The amplifier includes both balanced and unbalanced connections that can be connected simultaneously, allowing you to integrate the amplifier into a separate 2-channel system. The outputs are numbered for easy identification, and the outer channels are recommended for the mains to optimize heat distribution. The amplifier also includes a single trigger input and peak/clip indicators for comprehensive control and monitoring.
