NAD M12 Preamplifier / DAC
Built for the future, the M12 is neither a typical DAC nor a typical preamplifier. In fact, the M12 is a high-resolution digital audio hub that boasts a full roster of audiophile-grade features. Modular Design Construction allows new features and functionality to be added now or in the future.
NAD’s DirectDigital™ processing, as well as a fully balanced Class-A buffer stage, provide amazing accuracy and transparency with a completely silent background. The M12 interfaces with all digital or analog musical sources, and renders them perfectly to power amplifiers and active loudspeakers with its balanced or single-ended outputs.
