About the ATI AT528NC

The ATI AT528NC is an eight-channel Class D power amplifier introduced in 2018 by Amplifier Technologies Inc. It delivers 200 watts RMS per channel into 8 ohms and 300 watts into 4 ohms, utilizing Hypex N-Core® amplifier modules combined with ATI's custom gain stage and linear power supply. This amplifier incorporates advanced features such as microprocessor control for turn-on delay, automatic AC power recognition and configuration (auto-detecting 117V or 230V power), and a novel sleep circuit that powers down output modules after 10 minutes of no input signal, resuming playback instantly upon signal detection. It offers a frequency response of 5Hz to 20kHz, total harmonic distortion below 0.02%, a damping factor of 1600, and a signal-to-noise ratio of 123 dB, ensuring high fidelity and dynamic range suitable for music and cinema applications. The amplifier is housed in a compact 3RU chassis measuring 432 x 150 x 394 mm and weighs approximately 66 lbs (30 kg). It features both RCA and XLR inputs with input sensitivity of 1.5V and gain of 28.5 dB. The AT528NC is manufactured in Southern California with rigorous quality control, including in-house toroidal transformers and Audio Precision testing for consistent performance. It carries a 7-year warranty and is The amplifier cannot be upgraded in channel count beyond eight channels.
