Whether you?re a beginner or regular performer, the Yamaha PSR-E473?s multitude of high-end features and performance-shaping options are sure to please even the most demanding keyboardists! This addition to Yamaha?s PSR-E series includes a whopping 820 lifelike instrument voices, 290 styles, and a wealth of rhythm and groove sounds. When testing this keyboard out at Sweetwater, we were highly impressed by the PSR-E473?s expressive potential; a pitch wheel, momentary Motion Effect button, and Live Control Knobs deliver real-time control for unique and dynamic performances. Dual 6W speakers provide a powerful sound that?s great for practice or jamming with others, plus the Mega Boost button kicks up your playing by 6dB for dramatic volume shifts. If you?re really looking to take your performance up a notch, the PSR-E473 has an external 1/4-inch mic input that lets your sing through your speakers and capture your voice with Yamaha?s Quick Sampling.
