The NAD 2100 is a power amplifier produced between 1988 and 1989, originating from Japan, and is characterized by its anthracite color. It has dimensions of 435 x 106 x 385 mm (WxHxD) and weighs approximately 9.5 kg. The power consumption stands at 330 VA and its original pricing was around 398 US dollars or 800 DM. The amplifier features two CINCH stereo NORMAL inputs with an input impedance of 10 kOhm and a capacitance of 600 pF, accommodating a signal of 850 mV. The technical specifications indicate that the continuous power output is rated at 60 W into 8 Ohms with a distortion level of 0.03%. Dynamic power ratings are significantly higher, delivering 200 W at 8 Ohms and up to 250 W at 4 Ohms. The total harmonic distortion is rated at less than 0.03%, while the damping factor exceeds 100 at 50 Hz with an 8 Ohm load. Frequency response is impressive, ranging from 3 Hz to 80 kHz (+0 / -3 dB), and it offers a signal-to-noise ratio of 100 dB at 1 W and 117 dB at 50 W. This model is bridgeable, allowing for a continuous power output of 100 W at 8 Ohms and dynamic power levels reaching 500 W at 8 Ohms and 660 W at 4 Ohms, with a peak current capability of up to 30 amps. The NAD 2100 shares its power amplifier modules with the NAD Monitor 3100, and it can also be configured as a mono power amplifier for additional channels.
