AM/FM Stereo Receiver (1978-79)
Enjoying novel and useful features, the CR-420 receiver combines super broadcast reception with the finest audio quality, and is currently setting new standards for receiver performance in it's class.
The unit features accurately matched performance specifications, functions and controls, fully measuring up to Yamaha's high standards for separate tuners, pre and power amplifiers.
The CR-420 offers an extremely wide range of output powers for which both noise and distortion are below the rated value, for the widest possible dynamic range in actual use.
The sophisticated differential gain technique enables the Yamaha to combine high station-getting ability, razor sharp tuning, and ultra-low distortion in the tuner section.
