MC402 specifications

The McIntosh MC402 is a powerful and elegant amplifier that represents the pinnacle of high-fidelity audio performance. This two-channel amplifier stands out in the McIntosh lineup, delivering a robust 400 watts per channel into 2, 4, or 8-ohm loads. It is designed for audiophiles who seek uncompromising sound quality and superior performance, making it an ideal choice for both home studios and high-end listening rooms.

One of the standout features of the MC402 is its unique Autoformer technology, which allows the amplifier to deliver the same power output irrespective of the speaker impedance. This feature ensures that users enjoy consistent performance whether they are using 2-ohm, 4-ohm, or 8-ohm speakers. The use of transformers is integral to maintaining fidelity and output power while providing an additional layer of protection for the amplifier and connected speakers.

Additionally, the MC402 employs a quad balanced circuit design, which helps to eliminate distortion and achieve greater clarity in sound reproduction. This approach ensures that the audio signal remains pure from input to output, allowing listeners to experience their music in the way it was intended to be heard. The dual-construction design of the amplifier not only enhances its aesthetic appeal with the classic McIntosh blue meters and sleek black glass front but also contributes to its durability and reliability over time.

The amplifier features a robust cooling system that includes large heat sinks to dissipate heat effectively, ensuring optimal performance even during prolonged listening sessions at high power levels. This aspect of its design guarantees that the MC402 maintains a consistent performance without overheating.

In terms of connectivity, the MC402 is versatile, featuring balanced and unbalanced inputs to accommodate a variety of audio sources. The amplifier also has a signal sensing circuit that automatically turns it on when an audio signal is detected and powers it down when the signal is absent, helping conserve energy and adding convenience for users.

Overall, the McIntosh MC402 amplifier combines cutting-edge technology with timeless design. Its impressive power output, advanced circuitry, and robust construction make it a top choice for those who demand the best in audio performance. Whether driving efficient speakers or high-power systems, the MC402 is engineered to elevate your listening experience to new heights.
