新的固态CD6 CD- DAC结合了超高分辨率的光盘播放机具有超高分辨率的数字 - 模拟转换器在一个紧凑的机箱。
许多技术和声波取得了进展,将更新这个模型从5-1/2岁CD5的前身,它取代。从REF DAC和CD9的发展中受益,该CD6采用单声道模式下运行,采用双主控振荡器的性能最高的四核24位DAC ,一个用于44.1/88.2/176.4采样率,其它为48/96/192kHz采样率。采样率转换是可选的所有输入,可播放的原始分辨率,或通过采样,包括光盘和USB 。此外,还有一个可选的数字滤波器提供快或慢衰减。
前面板的布局是相同的REFCD9 ,对左侧的可调光的显示。右侧有三个垂直LED显示器显示采样率( 192-176.4-96-88.2-48-44.1 ) ,输入( CD- RCA -USB- TOS1 - TOS2 ) ,和快 - 慢 - 升频功率。
有四个数字输入,包括异步USB 2.0HS ,同轴RCA ,和两个Toslink光纤。所有的输入处理24位/ 192K分辨率。正如你所期望的, CD6保留了飞利浦PRO2R运输,仍然可用的最好的专用光盘的机制。那简直是无法超越的光盘播放。除了数字输入,后面板包括两个数字输出( AES / EBU和BNC ) ,单端RCA和XLR平衡输出。
固态音频研究CD6(9000美元)提供了从它的异步USB和3 S / PDIF输入(1同轴S / PDIF和2的Toslink)24/192播放。该CD6是,很明显,亦配备了CD播放器,是你盘纺纱好消息,同时有RCA和XLR输出对。
更换古老CD5,音频研究已经发布了新的CD6其中包括异步USB以及其他通常的数字输入。里面有运行的双打/上采样无论通过USB进来和四倍44K和48K数字源均衡配置的四路DAC。
定价为$9,000的用户也将能够两个过滤器之间进行选择。 AR表示,他们看到的CD6为圆盘集合和电脑音频之间的桥梁。
Audio Research發表一部取代CD5的入門級唱盤CD6,除可播放CD,還支援光纖、同軸DAC、非同步傳輸USB.
