RADIUS ポータブルDAC RK-DA50C

コメント不要で即購入OK

【音質とポータブル性を追求】
ポータブルヘッドホンアンプに求められるものは音質とコンパクトさ。本製品はその両方において非常に優れていて、24bit/192kHzのハイレゾ再生に対応。また接続したリモコン・マイク付きイヤホンの操作機能をそのまま使え、通話も可能。ポータブル環境での圧倒的なパフォーマンスを発揮します。

【Qualcomm社製の高品質チップを搭載】「Qualcomm Aqstic DAC」を備えており、消費電流を極限まで抑えながらも、広いダイナミックレンジ・低歪み・高い周波数応答特性に優れています。また、USB入力からヘッドホン出力までの信号処理をチップ単体で行うため、効率的な基板設計が可能となり筐体の小型化が実現しました。

【高精度なD/Aコンバートを実現する位相同期回路】
音源のデジタル信号をアナログ信号に変換する際、38.4MHzの外付けの水晶発振器から9.6MHzと11.2896MHzの2種類のマスタークロック信号を、時間誤差±0.00001% で生成します。48kHz系の音源と44.1kHz系の音源に対しマスタークロック信号を切り替え、内部で生成する音の揺らぎを限りなく抑制することで、高精度なD/Aコンバートを実現しました。

【省電力かつ音の再現性の高いH級ヘッドホンアンプ】
本チップに備わるH級ヘッドホンアンプは、信号レベルが低い時には電源電圧を落としてイヤホンへ供給する電力を抑え、信号レベルが高い時には電源電圧を上げて、より多くの電力を供給します。信号レベルの大きさに合わせて効率良く動作するため、接続先機器の消費電流の低減が期待できます。また、内部で負の電源電圧を生成することで信号からの直流成分を排除。アンプ出力とイヤホン間の、特に低音域へ悪影響を及ぼす大容量コンデンサーが不要となり、優れた楽曲の再現性を発揮します。

【高純度の単結晶銅と銀メッキ単結晶銅のツイストケーブル】
単結晶銅は特別な鋳造方法により信号伝送方向の結晶粒界(結晶同士の隙間)をなくし、不純物等の混入を低減した導電性に優れる極めて純度の高い導体です。銀メッキ単結晶銅は外観の美しさを向上させると共に、絶縁処理工程での熱による導体の劣化を防ぎます。単結晶銅の優れた電気的特性や柔軟性を損なうことなく、より高いS/Nを実現します。
