ATI AT4000 Signature Series Modular Power Amps, 2-7 Channels

Morris Kessler’s Statement of What a Great Power Amplifier Should Be The ATI AT4000 Signature Series brings the design philosophy and circuit sophistication of ATI’s award-winning AT6000 Series to a slightly lower-powered, more attainable platform — 200 watts per channel into 8 ohms and 300 watts per channel into 4 ohms, all channels driven. Designed and assembled in the USA, the AT4000 Series is available in 2, 3, 4, 5, 6, and 7-channel versions, making it ideal for serious stereo, home theater, and immersive audio systems that demand clean power, low noise, and long-term reliability. This is not mass-market amplification. This is Morris Kessler’s Signature Series — a modern expression of the engineering discipline that began with SAE and continues today through ATI.
