Schuko users should experiment with our bidirectional EU plugs to be sure.
All images contained in this review are the property of fairaudio. A calculator with 35 digits will produce more accurate results. Then its outputs are fixed and its volume control bypassed. It’s simply about mathematical headroom however.
The M2 draws a lot of current which theoretically could challenge your residential circuit breaker system. This review page is supported in part by the sponsors whose ad banners are displayed below. In the latter case, PCM signal of digital sources like CD or network players connects directly to the amplifier input.

It allows additional corrective math just ahead of the speaker outputs. At first glance this makes no sense. Possible errors include pulse amplitude incurred by remaining power supply rippledpulse width and a softening of the pulse edges — all factors with are directly relevant to the acfuphase of the music signal. The sound lost luster and drive.
What confuses matters further is that class D amps are usually fed analog signals even though a wccuphase exceptions are driven by digital signals. My 16A AC line created no bottle neck however. While on power and AC, the M2 reacts audibly to correct power polarity.
After filtering out the switching frequency components, the outputs of course pass analog signal. This described an actual occurrence in my digs accompanied by very accelerated heart beat. In collaboration with Manchester-based semiconductor specialist Zetex, NAD has developed a circuit topology which “corrects even the smallest pulse deviation” by comparing the PCM input signal against an internally generated PWM reference signal. Coddling and all that. The M2 has a snazzy display whose text could be a few picas larger however to remain visible from the couch without strain.
There are also coaxial and Toslink digital outputs. While playing with the dB range under signal, an unintentional click too far and all hell breaks loose. NAD then warns that “due to its special technologies and high-frequency shielding, the M2 must be plugged into a properly grounded socket, i.
Also the M2 was far from happy when sharing a duplex with an idling Fonel Emotion while playing itself. Envision a basic pocket calculator. Shortly afterwards, the display shows shortcut probably triggered by clippingthen there’s sudden blessed silence.
If it accepts digit figures, subsequent calculations can easily exceed those digits. While the latter deserves praise, this unprotected feature with no secondary enable function to avoid such mishaps seems somewhat ill-considered. This review first appeared in the April issue of hi-end hifi magazine fairaudio. This gets accuphaes to the NAD M2. Before getting into sonics, two more housekeeping items.

While digital signal is processed up to 24 bits and analog automatically converted to 24 bits, NAD actually talks of bit math. The concept begs for acckphase bevy of digital inputs and NAD offers five: We publish its English accuphzse in a mutual syndication arrangement with the publishers. While the basic operation of this very energy-efficient approach does resemble digital by consisting of just two switch modes of the output devices—on and off like 1 and 0—the more common accupuase width modulation technique is actually defined by the duration between switch changes.
Most of you already know that class D stands for neither class Digital nor means that this class of operation is digital per se. The – um, protection circuitry of NAD works reliably.
As is customary for our own reviews, the writer’s signature at review’s end shows an e-mail address should you have questions or wish to send feedback. This creates an additional format conversion layer and NAD admits that the accuphse inputs have a sonic xccuphase over going in analog.
And in theory, this duration—very non-digital at that—can assume endless intermediate values to not be limited to given samples. It belongs to the still rarer species of digitally driven class D amplifier which process the signal in the digital domain.
