SHARP: 1-Bit Digital Audio Gallery


While personal MD players offer convenience and portability, they typically sacrifice sound quality to do so. Not any more. The MD-DR480H/470H takes portable music to new levels of fidelity, thanks to its cutting-edge SHARP technology. With its 1-bit digital amplifier, full-bridge output, and 4-pole earphone plug, the MD-DR480H/470H is nothing less than a small-scale revolution in sound.


The MD-DR480H/470H has all the music-playing stamina you need. Thanks to the low power consumption of the LSI circuit, you can enjoy up to 122 hours^1 of continuous playback – 2.5 times as much as on a conventional model. And when it comes to recording, the MD-DR480H/470H keeps going for a tireless 57 hours^2. Time to start planning your next MD marathon.

	The lifelike fidelity of 1-bit has been taking the audiophile world by storm. And now it's available on a smaller scale, so you can take it with you anywhere. Get ready, then, for a pleasant surprise. The MD-DR480H/470H's compact 1-bit amplifier will bring stunning new levels of realism to your portable music world.


	SHARP's newly-developed LSI circuit anticipates and compensates for potential signal distortion. It reduces distortion almost as effectively as a full-sized 1-bit amplifier. The result of all this is sound much cleaner than you would expect on a portable MD player.


	Distortion vs Volume Level	Distortion vs Frequency


	Conventional portable MD players employ half-bridge outputs. The MD-DR480H/470H, however, uses a full-bridge output to more fully separate the + (plus) and – (minus) signals. Signal noise and distortion are cancelled out, yielding an extremely pure signal stream.
		Noise Reduction Process


	SHARP's engineers thought of everything, even the earphone plug. The MD-DR480H/470H's premium-quality 4-pole plug clearly separates the left and right channels. In tandem with the full-bridge output, the 4-pole plug guarantees exceptionally clear sound.
