Careful Design and Engineering

NAD has an enviable reputation for creating great sounding products at very affordable prices and nowhere is this more evident than in NAD’s CD Players. NAD’s veteran engineers know exactly where to spend just a little extra money for a better quality part, in order to extract the very best sound from the Compact Disc. CD Players use mechanical, digital, and analog technology to produce sound, and all three forms of engineering greatly affect the end result and require careful design and engineering.

A solid mechanical foundation is paramount in reducing external vibration and providing precise location of the CD drive mechanism. This allows smooth operation and a minimum of tracking errors. Heavy gauge steel and non-resonant plastic moldings are carefully engineered to provide optimum results. The transport is mounted on reinforced steel rails and over 30 fasteners are used to lock the assembly together and maintain precise dimensional integrity.

Precise clocking of the digital data stream allows the Wolfson 24 bit DAC to provide accurate linearity for the PCM data conversion to analog waveform. Audio OP Amps buffer the output without adding noise or distortion to the music. Multi-layer PCBs using surface mount components allow for an enhanced circuit layout with very short signal paths. Powering these elements is a custom designed active power supply that provides multiple regulated voltages to the transport, digital circuits, analog circuits, and the control and display circuits. The result of this careful engineering is a sound that is at once both detailed and natural, with dramatic dynamic contrasts.

The NAD C 538 includes many desirable features that enhance listening pleasure. Front panel controls are duplicated on the hand held remote allowing Play, Pause, Skip, and Scan functions. In addition, many more features are available from the remote handset, such as RANDOM: Tracks/files are played at random mode, PROGRAM: Enter or exit program mode, REPEAT: Track, file, folder or whole disc is repeated, RPT A-B: Playback sequence is repeated. The dimmable dot matrix display shows tracks, total playing time. Track time, disc time, and remaining time are all available. The C 538 also can play CD-R/CD-RW discs allowing you to burn songs from your computer for playback on your CD Playing system.

Because these songs are encoded in MP3 or WMA format, you can fit up to 10 hours of music on a single disc which is great for party mixes and ambient listening. There are also both optical and coaxial digital outputs that allow connection to an external DAC or digital component (like an AVR) to provide the most efficient and best sounding system setups.

Although music downloads and streaming continue to grow in popularity, CDs are still the primary listening source for millions of people around the world. NAD continues to innovate and improve its CD Players to get improved performance while keeping prices low. Whether you are creating your first home system, or upgrading your current CD Player, you should consider NAD’s 45 year record of excellence, and its commitment to music lovers everywhere, when selecting a new player.

NAD的CD播放机以其实惠的价格创造出了令人羡慕的好声音，这一点在NAD的CD播放机上体现的淋漓尽致。NAD的资深工程师们知道，只要多花一点钱，就能得到更优质的零件，从而从光盘中提取出最好的声音。CD播放机采用机械、数字、模拟技术来制作声音，这三种形式的工程都对最终的效果有很大的影响，需要精心设计和工程。

坚实的机械基础是减少外部振动和提供CD驱动机构的精确位置的关键。这使得操作平稳，跟踪误差最小化。重型钢和非共振塑料模具经过精心设计，可提供最佳效果。运输机安装在钢筋钢轨上，并使用了30多个紧固件将组件锁在一起，保持精确的尺寸完整性。

数字数据流的精确时钟化使Wolfson 24位DAC能够为PCM数据转换为模拟波形提供精确的线性度。音频OP放大器可以缓冲输出，不会给音乐增加噪音或失真。使用表面贴装元件的多层印刷电路板可实现增强型电路布局，信号路径非常短。为这些元件供电的是一个定制设计的有源电源，为传输、数字电路、模拟电路、控制和显示电路提供多路稳压电源。这种精心设计的结果是，它的声音既细腻又自然，具有戏剧性的动态对比。

NAD C 538包含了许多理想的功能，提高了聆听的乐趣。前面板的控制功能与手持式遥控器相同，可以实现播放、暂停、跳过和扫描等功能。此外，遥控听筒还提供了更多的功能，如RANDOM等。以随机模式播放曲目/文件，程序。进入或退出程序模式，REPEAT：重复播放曲目、文件、文件夹或整个光盘，RPT A-B：重复播放顺序。可调光的点阵式显示，显示音轨、总播放时间。音轨时间、光盘时间、剩余时间均可显示。C 538还可以播放CD-R/CD-RW光盘，允许您从电脑上刻录歌曲，在CD播放系统上播放。

因为这些歌曲都是以MP3或WMA格式编码，所以你可以在一张光盘上容纳多达10个小时的音乐，这对于派对混音和环境音乐来说是非常不错的。此外，还有光纤和同轴数字输出，可以连接到外部DAC或数字组件（如AVR），提供最有效和最佳的系统设置。

尽管音乐下载和音乐流媒体不断增长，但CD仍然是全球数百万人的主要收听来源。NAD不断创新和改进其CD播放器，以获得更好的性能，同时保持较低的价格。无论您是打造您的第一套家庭系统，还是升级您目前的CD播放器，在选择新的播放器时，您都应该考虑到NAD 45年来的卓越记录，以及它对各地音乐爱好者的承诺。
