For optimum compatibility with the broadest range of sampling frequencies, the DA-300USB is equipped with two master clock crystals, instead of the usual one.</p><p>For the widest dynamic range and lowest distortion, the DA-300USB features sophisticated digital signal processing, including Denon's exclusive Advanced AL32 processor that delivers vastly improved detail especially through the critical midrange band, providing noticeable improvements in clarity with low level softer sounds.</p></div></div></div></div></div><div class="section bg_RadialContent3"><div class="wrapInner"><div class="row- marT30 marB30"><div class="col_3 c_OffWhite MS_100 M_50"> <hgroup class="f30 c_White marB20 MS_noTMar"> <h4 class="ff_77">Audiophile</h4> <h5 class="ff_45">Grade Design</h5> </hgroup> <div class="lH24"><p>Housed in a sleek casing, the DA-300USB features no less than 7 separate printed circuit boards, to ensure the highest isolation between circuit blocks. Powered by a 15V/1A AC adapter, the DA-300USB features sophisticated DC power conversion technology with a power block that delivers separate DC voltage sources to power the various stages.</p><p>To ensure the most stable and accurate digital audio and timing data at the critical D/A converter stage, the DA-300USB also features advanced isolator chips that combine high speed CMOS technology with unique on-chip micro air-core transformers. A total of 9 isolator chips are employed, with 18 channels of isolation, delivering superior common mode noise rejection and maximum protection against digital noise transfer between critical stages, compared to conventional optoisolators.</p></div></div><div class="col_3 M_50 M_imgFull MS_100 MS_imgFull"> <img src="" alt="" />  </div></div></div></div><div class="section bg_White"><div class="wrapInner"><div class="row- marT30 "><div class="col_6 MS_100"> <hgroup class="f30 ff_45 marB20 MS_noTMar"> <h4 class="c_PremiumBlue ff_77">Wide Range</h4> <h5 class="c_Black">of Connection Options</h5> </hgroup> </div><div class="col_3 M_50 MS_100"><div class="lH24"><p>The asynchronous USB-B port connects to your computer's USB-A port.
