The Anthem Statement M1 Amplifier.


Class D architecture provides value over traditional Class A and Class AB designs because of its efficient output and smaller form factor, both of which the M1 perfectly embodies, Anthem says. Its heat pipe cooling system and deep side-mounted heat sinks allow multiple M1s, with feet removed, to be rack-mounted directly on one another, each occupying only a single rack unit. Its fanless design also makes the M1 as well-suited for the quietest of listening rooms as it is the most crowded equipment closets.

“The Anthem design team conceptualized the M1 almost 10 years ago, illustrating just how much in-house design and engineering went into producing this amplifier,” said Mark Aling, director of marketing for Anthem. “More than just a slim, technologically advanced monaural, the M1 demonstrates that Class D architecture isn't fundamentally flawed, it merely 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 resources necessary to create such a groundbreaking product and strongly believe our customers will appreciate the effort.”

Despite the “D” in “Class D,” the Statement M1 is not a digital amplifier. It boasts the warmth and clarity of a traditional amp, in addition to a temporal resolution more than 80 times that of the audiophile-favorite SACD format. While Anthem’s Statement P5 outputs 500 watts with a 4-ohm load, the M1 delivers 2,000 watts to the same speaker, with total harmonic distortion remaining under 0.1% from 20 Hz to 20 kHz. (Into 8 ohms, it delivers 1000 watts with a less than 0.06% total harmonic distortion.) And frequency response is load-independent, so the difference in response between a 2-ohm load and an open circuit is 0.1 dB at 20 kHz. Between 4 ohms and 8 ohms there is no change in frequency response.

The Statement M1 attains this level of power and performance through the employment of a few key technologies, including a proprietary load monitoring system that relies on a Digital Signal Processor to monitor line voltage, output current, ground fault detection, temperature, and DC voltage at the output to ensure the highest possible output from either a 120V or 240V circuit.

Power Factor Correction maximizes available power by marrying the voltage and current cycles, enabling continuous output from the power supply through the entire AC cycle without contaminating the AC line with noise.
