The C 352 is the latest in NAD’s range of
affordably priced, yet very high performance
Integrated Amplifiers. Building on the strengths
of our highly acclaimed C 350 (Winner of
the 2002 Diapson d’Or), the C 352 boasts
many upgrades and refinements. Immediately
noticeable is the new cosmetic appearance
and more robust all metal construction of
the chassis, along with the improved remote
control handset. Inside, we’ve upgraded
the Pure Class A preamp and driver stage
modules using the latest high performance
semiconductors. The power supply has also
received a complete upgrade, with the larger
custom wound toroidal transformer and
105C smoothing capacitors contributing to
a 25% increase in output power, to 80 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!
The C 352 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 352 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 352 can be expanded
to meet future system needs. The C 352 sports 2 preamp 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, which has identical
amplification factor (gain) as the C 352’s power amp
section - is easily connected.
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 352 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 352 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 352 tone controls only work
at the frequency extremes leaving the critical mid-band
essentially unaltered. The tone control circuits can be
completely by passed by using the tone defeat switch. The
C 352 also incorporates NAD’s acclaimed switchable “Soft
Clipping” circuit, which significantly reduces the risk of damage to
loudspeakers due to prolonged high power operation.
Design: PowerDrive
The C 352 also benefits 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 352 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 we have the highly desirable characteristics of high dynamic
power and low impedance drive capability in one affordable
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 finally 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 find anything that comes close
to offering the C 352’s overall musical satisfaction, well-rounded
performance, and stellar value for money.
