The volume attenuator is very unique in that it uses discrete 1% precision resistors that

keep impedance (and noise) very low. It is arrayed in 3 stages to reduce the residual

noise in each amplifying stage and prevent the 'cascade effect' of noise that is present

in most preamp designs. This circuit also provides the balance control, and as a result

channel separation is superb and inter-channel cross talk is virtually eliminated. These

resistor arrays are switched using 15 volt digital switches under software control,

keeping all attenuation at the ideal point in the circuit architecture.

Low impedance stepped tone controls provide +/- 5 db of boost/cut in the bass and

treble regions, or can be configured to provide variable slope, or 'spectrum tilt' at +/-

3dB per octave.

Biamp function allows the use of a second amplifier or active subwoofer PREOUT 1,

and offers a high pass filter function on PREOUT 2, with selectable 40Hz, 60Hz, 80Hz,

100Hz or Full Range options. These are analog 2nd order filters configured around the

low impedance differential Class A output stage of the preamp. This output stage also

employs proprietary distortion cancellation circuitry.

A balanced line input is also provided using identical JFET buffers feeding a discrete

differential amp and yielding common mode rejection in excess of 80dB.

Separately regulated DC supplies are derived from the dual mono power supply.

Copper buss bars and discrete regulators keep circuit noise to an absolute minimum

throughout. The display and digital functions operate from an independent power

supply to prevent any interference with the analog signal path.

POWER AMP HIGHLIGHTS

The M3 features a Dual Mono design with separate unregulated and discrete regulated

supplies for different stages of the 2 channels. The custom wound Toroidal

transformers use proprietary magnetic shielding technology. High current rectifiers

feed low ESR 105C filter capacitors.

NAD's PowerDrive technology measures load impedance continuously on each

channel and adjusts the power supply voltage for maximum undistorted dynamic

power into the connected speaker at all times and under all operating conditions. The

signal processor also continuously measures temperature and average long term

power and, based on this information, chooses the optimum voltage.

PowerDrive allows the M3 to sound far more powerful than its already impressive 180

watt per channel rating would suggest. Totally effortless sound, even at elevated

levels, is the hallmark of the PowerDrive amplifier.

The M3 utilizes a wideband current-mode Class A voltage amp featuring large open

loop compensated bandwidth, and running from low noise stabilised power supplies.

NAD's patented current amp output stage starts with < 0.02 % static and dynamic

distortion open loop (before feedback); even into 3 ohms at 20-20k at all levels. By

utilizing small amounts of feedback the circuit returns distortion levels at all audible

frequencies that are at limit of measurement - less than 0.002%!

The super rugged output stage features 4 pairs of 150W discrete bipolar output

transistors per channel, for 50A peak undistorted output current. Massive heat sinking

assures a lifetime of trouble free operation.
