True. Pure. Enveloping.
The C372 represents the pinnacle of our cost effective, high-performance stereo integrated amplifiers that build on the technological strengths of its highly successful predecessors. At 150-watts per channel, this powerhouse of our line will best your greatest expectations delivering clean, reliable power.
Important Ventilation Notice for owners of the C372 Stereo Integrated Amplifier
At 150-watts per-channel, the C372 is capable of powering many of today’s demanding low-impedance, audiophile-grade speakers with the power and finesse of a traditional separates component system. The massive internal amplifier features a Holmgren™ toroidal transformer and NAD’s proprietary PowerDrive™ technology and can be bridged into a mono configuration to deliver a incredible 400-watts (8-ohms). The preamp section of the C372 is impressive on its own, boasting 7 line inputs, main-amp inputs and 2 preamp outputs. While there are direct access controls on the front panel, the SR-5 remote provides the convenient control of features and general use.

A CLoser Look
Immediately noticeable is the new cosmetic appearance along with the improved SR-5 remote control handset. Inside, we’ve upgraded the Pure Class A preamp and driver stage modules using the latest high performance semi-conductors. The power supply has also received a complete upgrade, with the larger custom wound toroidal transformer and 105C smoothing capacitors contributing to a 20% increase in output power, to 150 watts continuous. An improved tone control circuit and revised PCB layout has reduced distortion and noise to unprecedented levels. Taken together, these improvements mark a sharp upturn in performance that simply must be heard, to be fully appreciated!
Features:
The C 372 is fully remote controlled and comes supplied with the all-new NAD SR-5 system remote control. The remote control features an ergonomic form, with large buttons that are differentiated by shape and position, to make operation intuitive and enjoyable. The SR-5 will also operate many other NAD products such as CD players, tuners, etc.
Flexibility is another NAD strong point. The C 372 has 7 line inputs (including 2 tape in/outputs with dubbing facility) and the pre-amplifier section can be separated from the power amplifier for easy upgrades or adding ancillary equipment. Thus the C 372 can be expanded to meet future system needs. The C 372 sports 2 pre-amp outputs: Many systems benefit from the use of multiple power amplifiers for “Bi-Amping” (using separate power amplifiers to drive the bass and treble section of a loudspeaker). With the second Preout 2 facility an extra power amplifier, such as NAD’s C 272, is easily connected. There is an adjustable gain setting for this second Preout 2, allowing virtually any amplifier to work with the C 372. This output can also be used to connect a powered subwoofer, an increasingly popular option.
For remote on/off switching of ancillary components in a system, such as power amplifiers or active speakers, the C 372 is equipped with a 12V trigger system. When switching the amplifier on, the 12V trigger output is also activated which in turn can activate a 12V trigger input and switch on the remote devices. Besides the 12V trigger, the C 372 also has an AC switched outlet (North American version only) so you can easily switch your entire system on or off with the remote control or from the front panel. 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 C 372 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 C 372 also incorporates NAD’s acclaimed switchable “Soft Clipping” circuit, which signifi cantly reduces the risk of damage to loudspeakers due to prolonged high power operation.
Design: PowerDrive
The C 372 also benefi ts from NAD’s proprietary PowerDrive circuit topology, now well established and used throughout the NAD product range notably, in the highly reviewed models such as the C 320BEE and C 370. The PowerDrive topology allows the C 372 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 to enable an amplifi er 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.
But even the most carefully reported specs cannot fully describe the sonic performance of an amplifier. Only your own ears can fi nally judge our achievement. We urge you to listen and compare NAD to other products in its price range, and even higher. We don’t think you’ll fi nd anything that comes close to offering the C 372’s overall musical satisfaction, well-rounded performance, and stellar value for money.
