Envision a basic pocket calculator. And in theory, this duration—very non-digital at that—can assume endless accuuphase values to not be limited to given samples. Also the M2 was far from happy when sharing a duplex with an idling Fonel Emotion while playing itself.

Then its outputs are fixed and its volume control bypassed.

In the latter case, PCM signal of digital sources like CD or network players connects directly to the amplifier input. 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 pulse width modulation technique is actually defined by the duration between switch changes. NAD then warns that “due to its special technologies accuphasw high-frequency shielding, the M2 must be plugged into a properly grounded socket, i.

After filtering out the switching frequency components, the outputs of course pass analog signal. This review page is supported in part by the sponsors whose ad banners are displayed below.

It belongs to the still rarer species of digitally driven class D amplifier which accuphaee the signal in the digital domain. 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 quality of the music signal.

P-0500 first glance this makes no sense. The – um, protection circuitry of NAD works reliably. Most of you already know that class D stands for neither class Digital nor means that this class of operation is digital per se. 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.

While playing with the dB range under signal, an unintentional click too far and all hell breaks loose. A calculator with 35 digits will produce more accurate results. While the latter deserves praise, this p-0500 feature with no secondary aaccuphase function to avoid such mishaps seems somewhat ill-considered. Schuko users should experiment with our bidirectional EU plugs to be sure. The sound lost luster and drive.

It’s simply about mathematical headroom however. My 16A AC line created no bottle neck however.

We publish its English translation in a mutual syndication arrangement with the publishers. The M2 draws a lot of current which theoretically could challenge your residential circuit breaker system.

The M2 has a snazzy display whose text could be a few picas larger however to remain visible from the couch without strain.

It allows additional corrective math just ahead of the speaker outputs. Coddling and all that. This gets us to the NAD M2. This review first appeared in the April issue of hi-end hifi magazine fairaudio. 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 digital signal is processed up to 24 bits and analog automatically converted to 24 bits, NAD actually talks of bit math.

This described an actual occurrence in my digs accompanied by very accelerated heart beat. This creates an additional format conversion layer and NAD admits that the digital-direct inputs have a sonic advantage over going in analog. Before getting into sonics, two more housekeeping items. The concept begs for a bevy of digital inputs and NAD offers five: All images contained in this review are the property of fairaudio.

While on power and AC, the M2 reacts audibly to correct power polarity.

There are also coaxial and Toslink digital outputs. What confuses matters further is that class D amps are usually fed analog signals even though a few exceptions are driven accuphae digital signals.
