Anthem M1

Anthem M1 Power Amplifier

State-of-the-Art Monaural Amplifier

The highest sound quality at all volume levels, flat frequency response into any load, and stable into the most difficult loads. The Statement M1 is a state-of-the-art monaural amplifier delivering 1,000 watts into 8 ohms and 2,000 watts into 4 ohms or less with THD remaining under 0.1% from 20 Hz to 20 kHz. Designed and engineered in our advanced research center in Ottawa, Canada, the M1 is manufactured in our Toronto facility.

More than just a slim, technologically advanced monaural design, the M1 demonstrates that Class D architecture isn’t fundamentally flawed, it simply hasn’t been implemented well in the past, mainly because it required such a heavy commitment to R&D. We’re fortunate to have the in-house resources to create such a groundbreaking product and one listen will reveal the truly extraordinary nature of this amplifier.

Cutting Edge Technology & Design

  • Full resolution of all of the sonic subtleties and complexities in the input signal.
  • Accurate reproduction of the full dynamic range of the signal.
  • Output stage is never allowed to clip.
  • No compression as output increases.
  • Flat frequency response into any load, without having to resort to digital conversion or equalization to compensate.
  • Stable into all loads including open circuit and short circuit.
  • A low noise floor.
  • Exceptional efficiency with low heat output.
  • An amp so mechanically silent it will suit even the quietest listening room.
  • A design that allows multiple units to be stacked with no danger of overheating.
  • All of the above delivered at a price point that while not inexpensive, delivers virtually limitless dynamic fidelity.

Best Value in the Market

The M1 enjoys all of the attributes of our award-winning Statement Class AB amplifiers but through exclusive Anthem technologies, goes far beyond the current capabilities of Class A, Class AB and prior Class D amplifiers in the market.The proprietary design employs all of the advantages of a Class D amplifier — high output, high efficiency, compact size — while avoiding the typical Class D limitations such as difficulty driving low-impedance (high-end) speakers, power line contamination, reliability issues and substandard audio quality. The absence of accurate dynamics is so common that it frequently goes unnoticed, but through the M1, music and movies are delivered with breathtaking realism.

Addressing the Class D bias

The “D” in Class D does not stand for digital. It was simply the fourth type of amp recognized and classified by the IEEE. The first was Class A, the second Class B, the third Class C, etc.
Contrary to the bias that exists among high-end enthusiasts and across the industry in general, the Class D design is not inherently flawed. The truth is that no existing designs have been able to reach the Class D’s inherent potential for performance. It is not the technology that yields fine audio performance but rather the implementation of the technology. At Anthem, we agree that most Class D amplifiers are poor performers. However the M1 uses Class D amplification of a different ilk (see later section on Class D for a full discussion).
The M1 is not a digital amp!
There are no A/D or D/A converters in the signal path. The amplifier’s control system continuously varies the width of the output pulse train in direct relation to the analog input signal. In essence, a side-to-side variation in width is analogous to a signal’s more familiar up-and-down amplitude variation, not at all the same as a digital string of 1s and 0s where all pulses have the same width.
Exceptional efficiency
Much has been written about Class D amps having twice the efficiency of conventional amplifiers at full output, but there’s more to this. Under normal conditions an amplifier operates at only a fraction of its full output capability. At 1/8th of its maximum output (the typical working level of an amplifier), our M1 is six times more efficient than a conventional amplifier.

Where mains voltage is 120V, one dedicated 15A circuit per amplifier is recommended depending on speaker. A 20A circuit is adequate for two amplifiers playing music where speaker impedance is 8 Ω. This product operates from a single phase AC power source that supplies between 108V and 264V at a frequency of 50 or 60 Hz.
