Canadian-based audio equipment manufacturer, Anthem, has just set a new bar for themselves in high-power amplification with their new Anthem Statement M1 Class D monoblock rackmount amplifier. The new M1 is engineered with advanced load monitoring and power factor correction technology to deliver up to 2400 W into one channel.

The M1 is also a true “double-down” amplifier, delivering 1000W into 8 ohms and 2000W into 4 ohms, with total harmonic distortion below 0.1% from 20 Hz to 20 kHz. As well, utilizing Class D architecture allows for a compact single rack unit size and efficient power demand. Anthem has also equipped the new Statement M1 with a heat pipe cooling system, allowing for fanless operation and stacked rack mounting.

Anthem’s Statement M1 uses a proprietary load monitoring system. Included in the system is a digitally modeled time constant of the circuit interruptor, something that does not trip the instant its maximum current is reached. Similar to slow-blow (time-lag) fuses and service panel breakers, it is meant to allow momentary current surges which do not last long enough to result in excessive heat.

In addition, the M1 contains active power factor correction to maximize available power. The result is that while the M1 can put out 2 kW continuously when fed by 240V mains, it can still put out 2 kW for the duration of typical musical peaks when fed by a dedicated 120V 15A line.

Additional specifications for the Anthem Statement M1 are below:
