Nad C 355 Brochure

It is fashionable to omit tone controls nowadays: However, provided that the tone controls are properly designed, they can be really useful tools in making improvements to the overall sound. The C355 tone controls only work at the frequency extremes leaving the critical mid-band essentially unaltered. The tone control circuits can be completely bypassed by using the tone defeat switch. The C355 also incorporates NADs acclaimed switchable Soft Clipping circuit, which significantly reduces the risk of damage to loudspeakers due to prolonged high power operation. Design: PowerDrive™ The C355 also benefits from NADs proprietary PowerDrive circuit topology, now well established and used throughout the NAD product range. The PowerDrive topology allows the C355 to deliver maximum performance under virtually any circumstance, independent of the loudspeakers it is driving. The circuitry automatically senses the impedance characteristics of the loudspeaker and will then adjust its power supply settings to best cope with that specific load. PowerDrive topology is a practical approach for enabling an amplifier to easily deal with musical dynamics and difficult speaker loads. Thus we have the highly desirable characteristics of high dynamic power and low impedance drive capability in one affordable package. NAD also takes a stand against the meaningless brochure power touted by many of our competitors by offering Full Disclosure power specs. We specify minimum continuous power, across the entire audible range of frequencies, at rated distortion, for both 8 and 4 Ohms with all channels driven simultaneously. Perhaps even more importantly, we also specify Dynamic Power at 8, 4, and even 2 Ohms, which better describes the way the amplifier will perform in the real world, with musical signals and reactive loudspeaker loads. Less Distortion = More Music Noise and distortion mask the fine details of a musical recording robbing musical texture and dimension and replacing them with non-musical artifacts. NAD is has spent the last 35 years perfecting our designs to have the lowest distortion and highest power in its price class. This cannot be overstated! Our competitors often rate distortion at only 80% of rated power, and even then cant match our very conservative spec of 0.03% at any frequency within the range of human hearing. At 80% power our distortion drops to 0.005% or less. Our noise spec is often 10dB (100 times!) less than that of competing amplifiers. This is far from trivial. However, even the most carefully reported specs cannot fully describe the sonic performance of an amplifier. Only your own ears can finally judge our achievement. We urge you to listen and compare NAD to other products in its price range, and even higher. We dont think youll find anything that comes close to offering the C355s overall musical satisfaction, well-rounded performance, and stellar value for money.
