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. Anthem are 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.
The M1 enjoys all of the attributes of Anthem’s 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.
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, they agree that most Class D amplifiers are poor performers. However the M1 uses Class D amplification of a different ilk.
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.
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.
