Anthem M1 Mono Power Amplifier


... a technological tour de force that outputs an enormous amount of power from what seems to be an impossibly small and lightweight package. ... If you’ve got a big home theater space to fill and speakers that require a great deal of power, the Anthem M1s are certainly worth considering


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 and 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


Power Output

Continuous, 20 Hz to 20 kHz, <0.1% THD+N

  • 8 Ω 1000 W
  • 4 Ω 2000 W
  • 3 Ω 2400 W
  • 2 Ω >2000 W depending on line voltage regulation

With 120V AC supply the amplifier’s maximum output into impedances 4 Ω and lower, as well as its maximum duration, vary depending on line voltage regulation.

Frequency Response

20 Hz to 20 kHz

  • Open circuit +/- 0.1 dB
  • 8 Ω +/- 0.1 dB
  • 4 Ω +/- 0.1 dB
  • 2 Ω +/- 0.2 dB

Power Bandwidth

1000 W at 8 Ω 5 Hz to 45 kHz


At 1 kHz, 8 Ω
  • 1 W 0.01 %
  • 10 W 0.01 %
  • 100 W <0.03
  • 1000 W <0.06


19 kHz + 20 kHz, CCIF 0.003%

S/N Ratio

Ref. 1000 W, IEC-A 113 dB 

Voltage Gain

29 dB

Input Sensitivity

100 mV for 1 W output, 3.2 V for 1000 W output (8 Ω)

Input Impedance

10 kΩ (RCA), 20 kΩ (XLR)

Damping Factor

800 to 1400 depending on frequency

XLR Configuration

Pin 1: Ground, Pin 2: Positive, Pin 3: Negative

Power Requirements

Consumption in a typical music/theater installation

  • Standby mode, 120V mains <1 w="" li="">
  • Standby mode, 240V mains <2 w="" li="">
  • Operate mode, idle 33 W
  • Typical operation 300 W
  • 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.
