Clear, Musical Reception (Section 1 of 3)
The C 427 is designed to focus on what matters most when listening to radio, delivering clean reception and natural musical clarity. Its carefully designed tuning circuitry and high-quality components help reduce background noise and interference, allowing broadcasts to sound more open and enjoyable. Whether listening to music or spoken-word programming, stations come through with greater stability and consistency.

Easy, Intuitive Listening (Section 2 of 3)
Listening to the radio should feel relaxed and intuitive. The C 427 makes it easy to find and enjoy stations with Auto Search tuning that locks onto clear signals, while FM Mute keeps tuning quiet between stations. The Blend function helps improve sound quality on weaker stereo broadcasts, making listening more comfortable over longer sessions. A smooth rotary control and clear display keep operation straightforward and distraction-free.

Seamless System Integration (Section 3 of 3)
With space for 40 presets, the C 427 lets you organise your favourite AM and FM stations and access them quickly. Station names and radio text are displayed clearly, so you always know what you are listening to. Preset information is stored internally, so your settings are remembered even if the unit is disconnected from power. For more advanced systems, RS-232 and IR inputs allow easy integration with external control solutions, while efficient power management keeps energy use low when the tuner is not in use.
