NAD C 165BEE Stereo Preamplifier (DU)

C 165BEE

Stereo Preamplifier

Distinguished amongst analogue preamplifiers, the C 165BEE is built to be the heart of any advanced home audio system. Starting with six line level inputs, including MC/MM phono input, the C 165BEE is incredibly flexible. Featuring a superbly designed tone control circuit, the C 165BEE is an exceptional example of how to implement high-fidelity tone controls by affecting only the frequency extremes and leaving the critical midrange untouched, while also offering a bypass option. With a 12V-trigger output and IR inputs and outputs on the rear panel, the C 165BEE is ready to integrate with CI control systems. With outstanding build quality and true engineering sophistication, the NAD C 165BEE is the preamp you’ve been waiting for.

C 165BEE是模拟前置放大器中的佼佼者，是任何高级家庭音响系统的核心。C 165BEE有6个线级输入，包括MC/MM声道输入，灵活性极高。C 165BEE拥有一个设计精良的音色控制电路，它是如何实现高保真音色控制的杰出典范，只影响极端频率而不触及关键的中音，同时还提供了一个旁路选项。C 165BEE的后面板上有一个12V触发输出和红外输入和输出，可与CI控制系统集成。NAD C 165BEE是您期待已久的前级放大器

Performance Far Beyond Expectation

The C 165BEE is an all-new design representing a lifetime of design experience from NAD’s renowned Director of Advanced Developments, Bjørn Erik Edvardsen. New semi-conductors and improved production techniques such as surface mount devices (SMDs) have created opportunities for performance far beyond expectation when compared to previous products in this price range. Compared to its predecessor the C 162, an improved tone control circuit and revised PCB layout has reduced distortion and noise to unprecedented levels when combined with the high signal capacity of the NAD Class A Gain Modules.

远远超过预期的性能

C 165BEE是NAD著名的高级开发总监Bjørn Erik Edvardsen的全新设计，代表了NAD一生的设计经验。新的半导体和改进的生产技术（如表面贴装器件（SMD））为该价格区间的产品创造了远超预期的性能。与前代产品C 162相比，改进后的音色控制电路和改进后的PCB布局与NAD A类增益模块的高信号容量相结合，将失真和噪声降低到了前所未有的水平。
