AM/FM Stereo Receiver (1978-79)
Accurately matched performance specifications, functions and controls give overall performance which fully measures up to Yamaha’s high tuner, pre and power amplifier standards.
The CR-820 offers an extremely wide range of output powers for which both noise and distortion are below the rated value, for wide dynamic range in actual use.
Both signal strength and centre-zero meters are provided, with the signal strength meter doubling as a signal quality meter on FM.
