The NAD 2400 is a power amplifier that was produced between 1989 and 1992, designed to deliver robust audio performance. This amplifier features a continuous power output of 100 watts into 8 Ohms with very low total harmonic distortion (THD) of less than 0.03%. The dynamic power capabilities are impressive, reaching 370 watts at 8 Ohms, 400 watts at 4 Ohms, and 440 watts at 2 Ohms. It has a frequency response that spans from 3 Hz to 100 kHz, ensuring both deep bass response and high-frequency clarity. The amp employs a dual rail Class G circuit topology, which provides efficient power management by utilizing different power supplies for low and high power demands. The NAD 2400 includes various features such as a soft clipping mechanism, allowing it to handle transient spikes in audio without distortion. Additionally, it is bridgeable, providing 200 watts at 8 Ohms and dynamic power of 800 watts at 8 Ohms when operated in bridge mode. The unit offers 2 Cinch stereo inputs and 1 output, and it boasts a signal-to-noise ratio of 98 dB at 1 watt and 118 dB at nominal power. The amplifier's design includes a single finned heat sink and weighs 10 kg. The typical power consumption is rated at 390 VA. This model also includes an impedance switch for optimizing performance with either 4 or 8 Ohm speakers, enhancing its versatility in various audio setups.
