Our Monitor Series stereo receivers are unique in the industry. No design compromises are made simply
to meet a price point. Rather , NAD's receivers contain exactly the same circuitry as NADs high-
performance separates. The 7100 consists of the 3100 integrated Amplifier, with its astonishingly large
margin of dynamic headroom for the uncompressed peaks and climaxes in todays digital recordings,
combined with a very sensitive and selective digital tuner.

A remote control is include for added convenience, allowing armchair operation of numerous key
functions; volume, tuning (14 presets or station search), low level muting, six input selectors, and power
on off, The remote control actuates a miniature DC motor on the volume control shaft, avoiding the
potential noise and distortion of electronic volume circuits.

The tuner section of the 7100 employs substantially the same circuitry as NADs 1700 Preamplifier,
Tuner-including a sensitive dual-gate MOSFET input stage, a low-distortion quadrature detector, a PLL
multiplex decoder with uniformly wide stereo separation, and a three-stage e |.F . circuit whose narrow-
|.F. 1 mode cleanly extracts weak signals from the skirts of strong stations. FM NR improves the
listenability of stereo signals and provides a 50 dB stereo quieting sensitivity y of just 26 dBf (5.5uV into
75 ohms) . Up / down buttons provide manual tuning or skip to the next strong station.

With overload-proof line inputs, a feedback-operated volume control, and quiet low-impedance tone-
control circuits, the 7100 accommodates a dynamic range greater than 110 dB, preserving the
transparent clarity of the finest recordings . The MM, MC phono pre-amp has very low noise, precise
RIAA equalisation , correct interfacing with the complex impedances of phono pickups, and plenty of
headroom for high-level peaks without distortion.

Based on the 3100 Amplifier, the 7100 produces 50 watts/channel of continuous power and over r200
watts/channel of tone-burst power for music. In bridged mode with the companion 2100 power amp,
those ratings are doubled. The high-current output stage can deliver 30 ampere peaks for precise
electromagnetic control of voice-coil motion and will drive impedances as low as 2 ohms with ease and
authority. With the greatest ratio of useful power to price of many receivers on the market today , the
7100 Receiver is an astonishing value.
