NAD is a brand that specializes in high-fidelity audio equipment and electronics.

The NAD S 400 is an FM tuner designed to complement audio systems with a focus on sound quality and simplicity. Introduced around 1998, it features a robust build with thick brushed aluminium construction and a clear, ergonomic interface. The tuner includes advanced components such as a dual-gate MOSFET RF amplifier setup that utilizes two independent antenna inputs for optimized reception without interference. Its advanced filtering and sensitivity offer the potential for high-quality audio from both weak and strong signals. The S 400 also features a remote control and allows for 30 user-programmable preset stations, which store not just the frequency but also the selected features per station. The interior design includes a toroidal transformer and separate power supplies for various circuits, ensuring minimal interference and maintaining audio integrity. A balancing act between performance from weak signals and audio quality from stronger ones is achieved through its user-selectable bandwidth settings.
