Superior Sound that Lives up to the Standards of the PianoCraft Series The foundation of the MCR-332's excellent audio performance is a Yamaha-developed digital amp that provides smooth, unforced sound output. The receiver's separate digital and analog low-noise circuitry ensures thoroughly high sound quality, which is delivered by new-design speakers. Digital USB Connection for iPad and Other USB Devices A USB terminal on the top of the unit makes it quick and easy to plug in an iPad or other USB device. The digital connection permits fast, loss-free signal transmission. Dock digital connection for iPod, iPhone The iPhone/iPod dedicated dock provides a digital connection, which means that the digital signal from the iPhone/iPod is transmitted directly to the receiver. This minimizes noise interference and allows use of the MCR-332 DAC, rather than the /iPhone/iPod DAC, resulting in more precise sound reproduction.
