Panasonic's SD Players Promise Sound True to Original

摘要

Matsushita Electric Industrial Co., Ltd. (Panasonic) has released three Secure Digital (SD) audio players worldwide. These are the SV-SD710, the SV-SD510 and the SV-SD310. Panasonic underscores the importance of the digital amplifier in each of these models (Fig. 1). Typically, digital audio players use analog amplifiers. With analog amplifiers, noise is sometimes introduced during digital-to-analog conversion. By using a digital amplifier, such conversion is not necessary. The sound that listeners hear thus remains truer to the original.
