The 150-watt-per-channel NAD C375BEE is far more than a bigger C355BEE. In fact, it is much closer in spec to the M3 integrated amplifier from NAD's high end Masters Series. It also incorporates an updated version of NAD's "Building Block" concept to make the addition of the PP375 phono module and other affordable future upgrades possible.Attention to the most minute detail is evident everywhere, from the heavy gauge steel chassis to the sophisticated power supplies and copper buss bars channeling almost absurd amounts of current to the custom gold plated speaker binding posts.
The C375BEE boasts many upgrades and refinements taken directly from the highly acclaimed NAD Masters Series M3 Amplifier. These include application of Bjorn Erik Edvardsen's innovative and patented Distortion Canceling Circuit in the output stage and BEE Clamp in the power supply.
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 you simply must be heard to be fully appreciated!
The C375BEE has seven line inputs (including 2 tape in/outputs with dubbing facility) and the preamplifier section can be separated from the power amplifier for easy upgrades or adding ancillary equipment. Thus the C375BEE can be expanded to meet future system needs.
Preamp and Subwoofer outputs
The C375BEE includes a pre-amp output. 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).
Additionally, there are two mono subwoofer outputs that can be connected to powered subwoofers, which is an increasingly popular option.
Bypassable tone controls
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 C375BEE 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 control button.
The C375BEE also incorporates NAD's acclaimed switchable "Soft Clipping" circuit, which significantly reduces the risk of damage to loudspeakers due to prolonged high power operation.
The C375BEE also benefits from NAD's proprietary PowerDrive circuit topology, now well established and used throughout the NAD product range. The PowerDrive topology allows the C375BEE 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 amplifier to easily deal with musical dynamics and difficult speaker loads. Thus it combines the highly desirable characteristics of high dynamic power and low impedance drive capability in one affordable package.
Getting high dynamic power from the power supply to your loudspeaker requires a fast wideband amplifier stage rugged enough to pass and control high peak currents without premature protection intervening. The safe operating limit for the C 375BEE has four times the capacity of the typical amplifier in this price range by using four pairs of 220W output transistors per channel.
Incredibly low levels of distortion and noise
The C375BEE has the lowest levels of distortion and noise available in its price class and is easily capable of embarrassing far more expensive products. To prove it, NAD uses Full Disclosure Power (FDP) - the most demanding criteria for performance measurement.
FDP specifies distortion under the most extreme conditions of low impedance loads and frequency extremes rather than the simple and easy 1 kHz at 8 Ohms test quoted by many of NAD's competitors. NAD uses this stricter performance criterion, because it more closely matches the demands of real music and real loudspeakers.
Maintaining specified distortion at 4 Ohms and at 20 Hz and 20 kHz is several orders of magnitude more difficult to achieve than the simple 8 Ohms and 1kHz test.
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 has spent the last 35 years perfecting its designs to have the lowest distortion and highest power in its price class. NAD's noise spec is often 10 dB (100 times!) less than that of competing amplifiers. This is far from a trivial difference as fine detail and nuance (micro dynamics) are often obscured by noise in lesser amplifiers, robbing a performance of that elusive sense of 'realism'.
For remote on/off switching of ancillary components in a system, such as power amplifiers or active speakers, the C375BEE is equipped with a 12-trigger system. When switching the amplifier on, the 12- trigger output is also activated, which in turn can activate a 12-trigger input switching on the remote devices. Besides the 12-trigger, the C375BEE also has rear panel IR input and output.
The C375BEE is fully remote controlled and comes supplied with the NAD SR 8 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 8 will also operate many other NAD products, such as CD players, tuners, etc. Flexibility is another NAD strong point.
