NAD Master Series M22 Details

NAD Master Series M22 Stereo Power Amplifier: Hybrid Digital Power for massive analog emotion
  • 225W x 2 into 8 ohms and 4 ohms (continuous output power at rated THD, 20Hz-20kHz, both channels driven)
  • Hybrid Digital Amplification for tight, detailed sound with amazing control and transparency
  • Clean dynamic power supply
The NAD M22 Stereo Power Amplifier lets you connect to the emotion of a live performance. It features wide open-loop bandwidth, extremely low-phase shift, almost non-existent noise, harmonic and intermodulation distortion independent of load, high current capability, low output impedance (high damping factor) uniformly at all audible frequencies-it all adds up to incredible performance. You just have to hear it to believe it – and feel it!

Hybrid Digital Amplification
The M22 incorporates the latest nCore™ amplifier technology licensed from Hypex to provide a nearly ideal amplifier with distortion below measurement, an ultra-high damping factor, and unconditional stability with any speaker. The all-discrete driver and output stage have also been improved for lower open-loop THD as well as lower idling losses, normally conflicting requirements with conventional IC driver circuitry. The result is tight, detailed sound with amazing control and transparency.

> Effortless power
Employing the latest generation of digital PowerDrive™, the M22 offers a minimum of 250W per channel with amazing reserves of dynamic power at lower impedances. The M22 is capable of >300W dynamic power per channel even in 8 ohms, and >600W in 2 ohms. It can effortlessly power any loudspeaker to live performance levels with amazing efficiency and low power consumption.

Clean and dynamic
The performance of the entire signal path is critically dependent on the power supply; in this case a well regulated, but not too tight, custom switch mode design. This allows maximum dynamic power, very high current yet with very low distortion. Secondary supplies are individually regulated and decoupled at each opamp for lowest possible noise and maximum dynamic range.
