Redefining the relationship between Digital Audio and Music
A20 is derived from A30 and delivers the very same reference-level audio performance, but without the CD ripping and library management functionality. A20 also replaces A30’s factory-fitted 10TB HDD with two user accessible bays to install one or two 2.5” HDDs or SSDs for the music storage capacity needed or desired.
Employing the same renowned dual-mono AKM 4497 chipset as that found in model A30, you can expect nothing but the best in sound quality. A20 is ideal for the user seeking exceptional audio performance from files and streams without the fuss or complexity of separate components.
A20’s scaled back design makes no compromise where audio performance is concerned. Music lovers who have no need for CD ripping functionality and want a high-end DAC without adding more boxes will find A20 to be a stellar foundation to any system.
重新定义数字音频和音乐之间的关系
A20 源自 A30,提供完全相同的参考级音频性能,但没有 CD 翻录和库管理功能。A20 还用两个用户可访问托架取代了 A30 的工厂安装的 10TB HDD,用于安装一个或两个 2.5 英寸 HDD 或 SSD,以满足所需或期望的音乐存储容量。
采用与型号 A30 中相同的著名双单声道 AKM 4497 芯片组,您可以期待最好的音质。A20 是寻求从文件和流中获得卓越音频性能的用户的理想选择,无需单独组件的麻烦或复杂性。
A20 的缩减设计在音频性能方面毫不妥协。不需要 CD 翻录功能并想要高端 DAC 而无需添加更多盒子的音乐爱好者会发现 A20 是任何系统的出色基础。
Key Features
主要特点
Aurender’s Best DAC
Aurender designed the A20 for those seeking the simplicity of an all-in-one unit without sacrificing a high level of resolution, transparency, and the reproduction of inner detail. Built around an integrated dual-mono AKM4497 DAC module, A20 delivers MQA full-decoding to get the best performance out of MQA content, as well as every other major digital audio format.
Aurender 的最佳 DAC
Aurender 为那些追求一体式设备的简单性而不牺牲高水平分辨率、透明度和内部细节再现的人设计了 A20。A20 基于集成双单声道 AKM4497 DAC 模块构建,提供 MQA 全解码,以从 MQA 内容以及所有其他主要数字音频格式中获得最佳性能。
Linear Power Supply with Integrated UPS
A fully-linear power supply architecture with extensive shielding prevents noise from being delivered to sensitive DACs. Four discrete toroidal transformers power the server system, digital outputs and dual-mono DAC respectively. A “super capacitor” based UPS system stabilizes A20 in the event of an abrupt loss of power.
集成 UPS 的线性电源
具有广泛屏蔽的全线性电源架构可防止噪音传递到敏感的 DAC。四个独立的环形变压器分别为服务器系统、数字输出和双单声道 DAC 供电。基于“超级电容器”的 UPS 系统可在突然断电时稳定 A20。
FPGA-Based Precision Clock
A20’s precision clock generation system incorporates a Field-Programmable Gate Array (FPGA) with sub 100fs jitter-reducing clock generator to precisely time digital audio data transmissions and minimize jitter to below negligible levels.
基于 FPGA 的精密时钟
A20 的精密时钟生成系统结合了现场可编程门阵列 (FPGA) 和低于 100fs 抖动减少时钟发生器,可精确计时数字音频数据传输并将抖动降至可忽略不计的水平。
Variable Output XLR & RCA Outputs
A20’s high quality Balanced (XLR) and Unbalanced (RCA) outputs guarantee compatibility with any preamp, integrated amp, or even power amps! A20’s DAC-level lossless volume control enables it to function as a preamp when connected directly to a power amplifier.
可变输出 XLR 和 RCA 输出
A20 的高品质平衡 (XLR) 和不平衡 (RCA) 输出可确保与任何前置放大器、集成放大器甚至功率放大器兼容!A20 的 DAC 级无损音量控制使其在直接连接到功率放大器时可用作前置放大器。
Dedicated Headphone Section
In addition to being a stellar Analog Output Network Player for loudspeaker systems, A20 also features a 1/4″ headphone output for quiet times.
专用耳机部分
除了作为扬声器系统的出色模拟输出网络播放器之外,A20 还具有 1/4 英寸耳机输出,适合安静时使用。
Upsampling DAC Option
A20 is capable of upsampling non-DSD files up to 705.6/768kHz to the analog outputs. Or leave upsampling off (default setting) for an untouched bitstream.
升频 DAC 选项
A20 能够将非 DSD 文件升频至 705.6/768kHz 至模拟输出。或者关闭升频(默认设置)以获得未改变的比特流。
User-Installable Storage Options
A20 is built with two trays for user-installable storage. Need a lot of capacity? Load up to 2 8TB SSDs! Not into storing files and prefer to stream? Leave them empty, and don’t pay for storage capacity you won’t use.
用户可安装的存储选项
A20 内置两个托盘,供用户安装存储。需要大量容量?最多可装载 2 个 8TB SSD!不喜欢存储文件而更喜欢流媒体?将它们留空,不要为不会使用的存储容量付费。
Digital Connectivity
Four digital inputs are provided: one RCA Coax, one BNC Coax and two Optical. These inputs allow connection of additional digital sources such as a CD transport, TV, etc. Any device connected this way will take full advantage of the superior sound quality of the DAC within the A20.
数字连接
提供四个数字输入:一个 RCA 同轴电缆、一个 BNC 同轴电缆和两个光纤。这些输入允许连接其他数字源,例如 CD 传输器、电视等。任何以这种方式连接的设备都将充分利用 A20 内 DAC 的卓越音质。
