Technical Description

McIntosh Laboratory, the company who introduced the world’s first amplifier that could be called “High Fidelity”, has done it again. The McIntosh engineering staff has cre- ated a power amplifier without compromise, using the most advanced McIntosh circuit design concepts.

A continuous average power output rating of 500 watts and with an output current of greater than 100 amperes, makes this not only the most advanced, but also one of the most powerful amplifiers McIntosh has ever manufactured. The distortion limits for the MC501 are no more than 0.005% at rated power output for all frequencies from

20Hz to 20,000Hz. Typical performance at mid frequencies is less than 0.002%. The true distortion readings on the MC501 are so low, it takes special measuring techniques to make accurate readings. The MC501 can deliver the best possible performance from any type of high quality Loud- speaker System.

Creating an amplifier with this level of performance did not come easily. Many months of design, testing and mea- suring were required. Extensive controlled listening tests, the ultimate form of measuring, were made before the final design was accepted.

MC501 specifications

The McIntosh MC501 is a high-performance monaural amplifier that exemplifies the blend of cutting-edge technology and exquisite craftsmanship inherent in McIntosh products. Renowned for its exceptional audio performance, the MC501 is designed to deliver powerful and precise sound reproduction, making it a prized component in any audiophile's collection.

One of the standout features of the MC501 is its output power, providing a robust 500 watts into 2, 4, or 8-ohm loads. This level of power ensures that the amplifier can drive even the most demanding speakers with ease, producing dynamic sound across various listening environments. The MC501 features a unique autoformers design, allowing it to maintain consistent impedance, which results in superior sound clarity and dynamics regardless of speaker type.

The technological advancements in the MC501 include McIntosh's iconic Power Guard circuit. This system monitors the audio signal and automatically reduces the amplifier's output if it detects any distortion, protecting both the amp and the connected speakers from damage. Additionally, the amplifier incorporates McIntosh's Sentry Biasing technology, which ensures optimal performance while preventing overheating, making it a reliable choice for extended listening sessions.

Aesthetically, the MC501 is as impressive as it is functional. It showcases the brand's signature blue watt meters and backlit logo, which not only enhance its visual appeal but also provide real-time feedback on power output levels. Its solid construction and elegant design make the MC501 a striking addition to any audio setup, embodying a luxurious look that is synonymous with McIntosh.

Moreover, the MC501 is engineered with a balanced design, featuring both balanced and unbalanced inputs to ensure compatibility with various audio sources. This flexibility allows users to integrate the amplifier seamlessly into their existing audio systems while maintaining the highest sound quality.

In summary, the McIntosh MC501 monaural amplifier delivers exceptional power, advanced technologies, and unrivaled sound quality. Its robust output capabilities, protective features, and stunning design make it a cornerstone of any high-end audio system, appealing to both seasoned audiophiles and newcomers looking to elevate their listening experience. With the MC501, McIntosh continues to uphold its legacy of excellence in the world of high-fidelity audio.
