"Natural Sound"

The A-420 is part of Yamaha’s 1985 “Natural Sound” range, and it lives up to its name, producing excellent sound quality. It delivers 50 watts RMS per channel into 8 ohms, and with the “high dynamic output power” design can deliver much more for instantaneous music peaks. It also features Yamaha’s constantly variable loudness contour control.
This model gained an excellent reputation for good reason! You’ll enjoy the way it sounds.
