The C 328 can wirelessly connect to any smartphone, tablet, or Bluetooth®-enabled device within range, to give you a seamless listening experience. Featuring a MM phono input, the C 328 breathes new life into vinyl LPs, thanks in part to NAD’s innovative Hybrid Digital™ amp technology. The C 328 also features a headphone amplifier, letting you connect your favourite headphones and settle back into your own world of detailed sound. Although more modest in comparison to other Classic Series amplifiers, the C 328 will fit perfectly into your existing system and bring you the musical nirvana you’ve been searching for.

45 年来，NAD 已将有志向的听众介绍到广阔的高保真世界。从我们的旗舰系列，到经济实惠的经典系列，NAD都有适合每个人的组件。继承了NAD一些最优秀的产品，NAD C 328提供了最基本的功能，同时坚定地坚持了NAD对精致声音的承诺。C 328可以无线连接到任何智能手机、平板电脑或蓝牙设备，为您带来无缝的聆听体验。C 328拥有MM唱机输入，为黑胶唱片注入了新的生命力，这要归功于NAD创新的Hybrid Digital™功放技术。C 328还配备了耳机放大器，让您可以连接您最喜欢的耳机，回到您自己的世界，享受细腻的声音。虽然与其他Classic系列功放相比，C 328的体积较小，但它能完美地融入你现有的系统，为你带来你一直在寻找的音乐涅槃。

Getting the Basics Right

When it comes to Classic Series amplifiers, no feature is overlooked. Low noise circuits, precise volume control action, and accurate channel balance are all key characteristics of the C 328. With the added bonus of proper input and output impedance traits, plus high overload margins and stability with difficult speaker loads, the C 328 is the best choice for audiophiles who are just starting to build their dream systems. The C 328 also includes a MM phono stage with precisely correct RIAA equalization, high overload margins, extremely low noise, and an innovative circuit to suppress infrasonic noise that is present on all LPs—all without affecting bass response.

掌握基础知识

说到经典系列功放，没有一个特点会被忽略。低噪音电路、精确的音量控制动作和精确的通道平衡是C 328的主要特点。加上适当的输入和输出阻抗特性，再加上高过载余量和高稳定性的扬声器负载，C 328是刚刚开始建立梦想系统的发烧友的最佳选择。C 328还包括一个具有精确的RIAA均衡、高过载余量、超低噪音的MM唱机级，以及一个创新的电路来抑制所有LP中存在的次声道噪音，所有这些都不会影响低音响应。

Versatility in Spades

The line inputs of the C 328 can accommodate all kinds of analogue source components. It offers ideal input impedance attributes with linear, ultra-low noise buffer amplifiers to prevent any sonic degradation caused by improper loading of the source device. The C 328 also features a separate headphone amplifier with low output impedance and very high output voltage capability, enough in fact to drive even high impedance studio monitor headphones. The low impedance line outputs can also connect to a subwoofer to further extend the versatility of the C 328.

黑桃的多功能性

C 328的线路输入可以容纳各种模拟声源元件。它提供了理想的输入阻抗属性，具有线性、超低噪声缓冲放大器，可防止因源器件负载不当而造成的音质下降。C 328还具有独立的耳机放大器，具有低输出阻抗和极高的输出电压能力，事实上足以驱动高阻抗的录音室监听耳机。低阻抗线路输出也可以连接到超低音扬声器，进一步扩展了C 328的多功能性。

Ready for Streaming

With support for Bluetooth, you can instantly connect and listen to the music service of your choice, or wirelessly stream music and playlists stored directly on your smartphone, tablet or computer. Plus, with its high performance digital circuitry, Bluetooth streaming has never sounded as good as it does with the C 328.

准备好了的流媒体

通过对蓝牙的支持，您可以立即连接并收听您所选择的音乐服务，或直接在智能手机、平板电脑或电脑上无线串流音乐和播放列表。此外，凭借其高性能的数字电路，蓝牙流媒体的音效从未像C 328这样好过。

Sophisticated Power

Since moving away from old-fashioned linear power supplies and Class AB output stages, NAD has developed even better performing circuits based on switch mode power supplies and Class D output stages. Once thought to be inferior to traditional topologies, NAD’s advanced work in this area has led to some of the best performing amplifiers on the market today. These new designs are linear over a wide bandwidth and provide consistent performance into all speaker loads, delivering a dramatic advancement.

The power supply of the C 328 is able to provide over 100 watts of audio output when needed. The C 328 can operate with any AC mains voltage from 100V to 240V and provides pure DC power to all of its various stages. This extremely efficient supply also provides near perfect regulation of voltage across a wide range of conditions and provides a solid noise-free foundation for the amplifying stages.

The C 328 uses a customised version of the proven Hypex UcD output stage. This allows for massive power with nearly immeasurable distortion and noise in the audible range. Every detail of this design has been carefully crafted and perfectly executed to wring out the best performance possible. The perfect starter amp for audiophiles and music lovers alike, the C 328 will flawlessly deliver NAD’s signature flexibility and expansive power.

精密的电源

自从摆脱了老式的线性电源和AB类输出级之后，NAD开发出了基于开关模式电源和D类输出级的性能更好的电路。NAD在这一领域的先进工作曾经被认为不如传统的拓扑结构，现在，NAD在这一领域的先进工作已经导致了目前市场上一些性能最好的放大器。这些新设计在较宽的带宽上都是线性的，并在所有扬声器负载中提供了一致的性能，带来了巨大的进步。

C 328的电源可以在需要时提供超过100瓦的音频输出。C 328可以在100V至240V的任何交流电源电压下工作，并为其所有的各级提供纯直流电源。这款效率极高的电源还能在各种条件下提供近乎完美的电压调节，为放大级提供了坚实的无噪音基础。

C 328使用经过验证的Hypex UcD输出级的定制版本。这使得C 328在可听范围内的失真和噪音几乎不可估量的情况下，实现了巨大的功率。该设计的每一个细节都经过精心制作和完美执行，以获得最佳性能。C 328是发烧友和音乐爱好者的完美入门级功放，它将完美无瑕地提供NAD标志性的灵活性和强大的功率。

D330

Midrange Driver

The D330 speakers incorporate an advanced midrange/bass drive unit, using the latest generation of Wharfedale’s woven Kevlar cones, bonded to a lightweight high tech foamed polyether surround. The driver delivers clarity and dynamic musical expression, for a detailed performance from a low-cost speaker.  The cone is driven by a super long throw voice coil motor system, for increased bass extension, with low frequency accuracy. The magnetic flux is controlled by a specially shaped pole plate that reduces inductance, ensuring distortion of bass frequencies remains at a minimum, while oversized ceramic magnets create high sensitivity and smooth response across the cone.

WFR Tweeter

The Wide Frequency Response tweeter was original developed in the Diamond 11 Series, and has been fine tuned for the D300 Series. The 25mm textile dome tweeter is built in its own cabinet, with fibre filling for damping. The tweeter is driven by an oversized ceramic magnet with a copper capped pole piece for flux control, and performs with a smooth and pure tone, producing defined high frequency detail.

Crossover and Cabinet

Wharfedale’s Advanced Software and Listening Iteration system has been used to carefully develop the new crossover to add emphasis on lifelike reproduction of voices and instruments. The crossover components use low loss polypropylene capacitors and laminated core inductors for the optimum signal transfer. The cabinets for the D330 speakers feature 28mm front baffles, profiled to reduce diffraction edge reflections from high frequencies. Inside the cabinet, critical bracing is employed on the panels to eradicate unwanted noise and the walls are lined with a specially developed fibre to absorb resonant sounds. The sound output by the speaker therefore remains free from external noise and colourations, to produce pure and delicate audio.

P-EQ Bass Reflex Port

The D330 speakers included the newly developed P-EQ Pressure Equalisation bass reflex port for deep and controlled bass. The bass frequencies are emitted through a downward firing port between the speaker and the plinth, sounding Omni-directionally into the room. This reduces the pressure differential between the high pressure port and the low pressure room, minimising turbulence and chuffing, whilst improving bass response and efficiency. The P-EQ bass port on the D330 creates the fundamental notes of bass instruments, to match the realism of the midrange and tweeter. With the down-firing port, the D330 speakers can also be placed closer to the wall than conventional speakers without affecting the bass response, making the speakers less obtrusive in a room.

The D330 speakers offer a remarkable performance from a budget, compact speaker, with an impressive midrange and fluid high end detail, with an accurate and controlled bass from the P-EQ port. The D330s are available in Black, White, Walnut and Rosewood finishes.
