NAD Stereo AM FM Tuner C427

Art and Sound

There’s nothing worse than bad reception when it comes to listening to radio. The harsh crackling sound of static can ruin the most sophisticated of systems, ultimately turning listeners away from the nearly 100-year-old medium. Thankfully, NAD has created a solution that will adequately deliver quality reception. With 40 presets available to program your favourite radio stations, the C 427 makes listening to the radio both smooth and enjoyable. When scanning through different stations, the C 427’s Auto Search will automatically stop at the strongest radio signal it encounters; the FM Mute feature removes inter-station noise, allowing only the strongest and clearest stations to come through. While keeping track of what stations you’ve programmed can be tricky, the C 427 actually stores all preset information, even when unplugged. With great reception and ease of use, the C 427 heightens all the things that make radio great, resulting in a gratifying experience.
