C 268

Stereo Power Amplifier

A remarkably affordable stereo amplifier, the NAD C 268 has features and technology unmatched by other amplifiers in its class. Designed for multiple stereo setups, the C 268 can be used in a variety of scenarios, including traditional stacks with a preamplifier or for bi-amping your favourite loudspeakers. The NAD C 268 is even bridgeable, seamlessly transforming its bountiful output from 80 x 2 to an outstanding 300 watts. Although the C 268 may appear to be a straightforward power amplifier, this Classic Series amp is brimming with rich features that will elevate your system.

NAD C 268是一款经济实惠的立体声放大器,具有其他同类放大器无法比拟的功能和技术。C 268专为多种立体声设置而设计,可用于各种场合,包括传统的堆栈式前置放大器或为您最喜爱的扬声器提供双路升压。NAD C 268甚至可以桥接,将其丰厚的输出功率从80 x 2无缝转换为300瓦特。虽然C 268看似是一款简单的功放,但这款经典系列功放却拥有丰富的功能,可以提升您的系统。

Amazing Flexibility

As with every amp in the Classic Series, we here at NAD have carefully thought through all the possible use cases and strategically chosen the most essential of features. Thanks to selectable balanced inputs, the C 268 is a natural mate for high-end preamps and processors. These inputs include a trim control useful for matching with other components, or for use in bi-amping speakers. A line out allows further addition of power on the same channel for extra speakers or subwoofers. On top of all this connectivity is a bridge switch that turns the C 268 into an amazingly powerful Monobloc amplifier.

You can also pair the C 268 with the NAD C 368 Hybrid Digital DAC Amplifier, and with both units bridged for mono, 300 watts per channel of distortion-free sound become available for your listening pleasure. The C 268’s auto-sense feature with selectable threshold is perfect for automating complex systems or for hiding the amp out of sight in a cabinet. Included with the C 268 is a ground lug that is very useful for eliminating ground loops and noise in complex multi-unit systems.

NAD C 268立体声功率放大器

惊人的灵活性

与经典系列的每一款功放一样,我们NAD在这里仔细考虑了所有可能的使用案例,并战略性地选择了最基本的功能。由于可选择的平衡输入,C 268是高端前级放大器和处理器的天然伴侣。这些输入包括一个微调控制,可与其他元件搭配使用,或用于双振扬声器。线路输出允许在同一通道上进一步增加电源,用于额外的扬声器或超低音扬声器。在所有这些连接的基础上,还有一个桥式开关,将C 268变成一个功能强大的单体功放。

您也可以将C 268与NAD C 368混合型数字DAC放大器配对使用,两台放大器均为单声道桥接,每声道300瓦的无失真音质将为您的听觉享受。C 268的自动感应功能带有可选择的阈值,是复杂系统自动化或将功放隐藏在机柜中的完美选择。C 268还附带了一个接地插头,对于消除复杂的多单元系统中的接地回路和噪音非常有用。

Getting the Basics Right

As a member of NAD’s Classic Series, the C 268 delivers a richly satisfying sonic performance thanks to its “music-first” features. Accurate channel balance, proper input and output impedance characteristics, and low noise circuits all come together within this one stereo power amplifier. Additionally the C 268’s line inputs, both balanced and single-ended, can accommodate all kinds of analogue source components by offering ideal input impedance traits with linear ultra-low-noise buffer amplifiers to prevent any sonic degradation caused by unfitting loading of the source device.

掌握基础知识

作为NAD经典系列中的一员,C 268凭借其 "音乐至上 "的特性,提供了丰富的音质表现。精确的通道平衡、适当的输入和输出阻抗特性以及低噪音电路都是这台立体声功率放大器的特点。此外,C 268的线路输入,包括平衡式和单端输入,通过提供理想的输入阻抗特性和线性超低噪声缓冲放大器,可以适应各种模拟声源元件,防止因声源设备负载不合适而导致的音质下降。

Sophisticated Power

Having moved 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 resulted in some of the best performing amplifiers regardless of basic design principle. The overall design of the C 268 is very linear over a wide bandwidth, providing dramatic advances over previous models with consistent performance into all speaker loads.

The power supply of the C 268 is capable of nearly 200 watts continuously and over 500 watts instantaneously, allowing for short term musical transients. NAD’s innovative asymmetrical PowerDrive fully utilizes every last watt available with its vast reserves of dynamic power available to accurately reproduce the most demanding music without distortion or compression. It can also operate with any AC mains voltage from 100V to 240V, and provides pure DC power to all the various stages of the C 268. This highly 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 268 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 ever last drop of performance.

精密的电源

在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。曾经被认为是传统拓扑结构的劣质产品,但NAD在这一领域的先进工作,无论基本的设计原理如何,都已经形成了一些性能最好的放大器。C 268的整体设计在宽广的带宽上非常线性,在所有扬声器负载下都能保持稳定的性能,比以前的型号有了显著的进步。

C 268的电源可以连续输出近200瓦的功率,瞬间输出超过500瓦的功率,可以实现短期内的音乐瞬态。NAD创新的非对称式电源驱动,充分利用每一个可用的最后一瓦特,其丰富的动态功率储备,可以准确地重现最苛刻的音乐,而不失真或压缩。它还可以在100V到240V的任何交流电源电压下工作,并为C 268的所有不同级提供纯直流电。这种高效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 268采用了经过验证的Hypex UcD输出级的定制版本。这使得C 268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打造和完美执行,以发挥出最后一滴性能。
