We are a leading producer of affordable amplifiers that produce the full measure of dynamic headroom
required by digital recordings. The “best buy” 2100 Power Amp is remarkable even by NAD’s standards.
While its rated power for continuous test tones is 50 watts channel, it’s effective power output for music
is an impressive 200 to 330 watts per channel (depending on speaker impedance). Thanks to NAD’s
unique Power Envelope circuitry, this high level of tone-burst power is available not just for brief
transients but for the full duration of complex chords and musical climaxes.
Yet the 2100 has the same modest size and low price as other “50 watt” amplifiers with 40,000 µ F of
power-supply capacitance, the 2100 delivers peak currents as high as 30 amperes to cope with the most
complex and reactive loudspeaker impedances. In addition to power and control, the 2100 has delicacy;
with a signal-to-noise ratio of 117 dB, it faithfully reproduces every subtle strand of low-level musical
detail and back-ground ambience. With its high-speed output stage and ultra-low distortion, the clarity
of its sound must he heard to he appreciated.
You can use either wide-hand inputs or filtered inputs 112Hz to 80kHz that strip off interference,
prevent intermodulation distortion, and protect your speakers from unwanted subsonic signals
The filtered inputs also have input- level controls that match your preamp’s output, balance levels in bi-
amped or surround systems and allow you to bypass your preamp and connect a line level source
directly to the power amp. Heavy-duty binding-post terminals provide secure low-resistance connections
for all types of speaker wire.
If you need more power, a rear-panel switch combines the amplifier’s two channels to form a mono amp
rated at 100 watts continuous and 500 watts tone-burst output. The efficiency and compact size of the
2100 also make it a perfect choice for hi-amplifying speakers.
(Suggestion for a high-definition audiophile system: instead of buying exotic and expensive speaker
cables to stretch across the room, install a bridged or bi-amped 2100 directly behind each speaker,
connected with ultra-short wires.
