For most manufacturers, the highest quality parts and most highly refined designs are used only in

separate audio components-in preamplifiers, power amplifiers, and tuners. Integrated amplifiers are

usually made to a less exalted standard, while all-in-one stereo receivers are regarded as compromise

products suitable only for casual listeners. But not at NAD. NAD electronics are designed in modular

form, and many of the same circuits are used in all product categories. The 3100 Integrated Amplifier,

for example, combines NAD’s robust 2100 Power Amplifier with high-quality preamplifier circuitry

derived from some of NAD’s finest preamplifiers. The pre- and power amplifier sections of the 3100 are

joined by removable external jumpers that allow you to insert external processors such as a surround-

sound unit or an electronic crossover for bi-amping in the signal path.

The power amplifier section of the 3100 employs all of the NAD innovations described on pages 4 and

5. Like the 2100 Power Amplifier, it is conservatively rated at 50 watts/ channel for sine-wave test tones,

while its Power Envelope circuit produces 200 to 330 watts channel of long-term tone-burst power for

the dynamic waveforms of music. Its high-current output stage, impedance selector, and heavy-duty

speaker terminals are designed to deliver maximum power to loudspeakers of any impedance. The

preamplifier section of the 3100 contains the same low-noise MM/MC phono stage as the 1700

Preamplifier/ Tuner and the same switchable Infrasonic Filter, flexible two-way tape connections, Bass

EQ, and ultra-quiet feedback-operated volume control as NAD’s state-of-the-art 1300 Preamplifier.

The tone controls are Baxandall bass and treble circuits, but with their parameters carefully selected to

allow substantial adjustments at low and high frequencies without altering the neutrality of the

midrange.
