Great Reception
Auto Search automatically stops at the next strong radio signal it comes across and optimizes tuning. Weaker radio stations can be tuned into manually. Stations that are quiet in Mono but noisy in Stereo can benefit from the “Blend” feature that narrows stereo separation and lowers noise. FM Mute eliminates inter-station tuning noise and only allows strong and clear stations to emerge from the silent background. Although AM can never reach the quality of any FM transmission, the C 427’s AM section retains excellent clarity together with the lowest possible background noise.
Performance Driven
The NAD C 427 also offers features to get the maximum out of the airwaves. The MOS-FET RF Front End design together with high quality components and careful PCB layout guarantees excellent sensitivity with low intermodulation distortion to provide a quiet and musically satisfying performance.
Whether you are looking for excellent performance, ease of use or the convenience of RDS, the C 427 offers all these with the value to high performance ratio for which NAD is so renowned.
