NAD has always had a formidable reputation when it comes to high performance
budget amplifiers. The NAD 3020 in its various guises, and more recently the NAD
C 320 and C 370 all have received world-wide accolades for their outstanding musi-
cal performance and superb value. As an encore NAD is proud to present an updat-
ed version of it's most popular amplifier, further enhancing that reputation.
Many of NAD's most innovative circuit designs have come from the creative mind of
Bjorn Erik Edvardsen, Director of Advanced Developments. The BEE moniker for
NAD's latest amplifier recognizes Erik's contribution to the marque, now in it's 30th
year. Building on the class leading performance of the C 320, the BEE version
includes many circuit refinements and upgrades, as well as a striking new revision
of NAD's classic, understated industrial design.
Features
The C 320BEE is fully remote controlled and comes supplied with the NAD SR4 sys-
tem remote control. The remote control will also operate other NAD products such
as CD players, and tuners. Flexibility is another NAD strong point. The C 320BEE
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 320BEE can be expanded to meet future
system needs.
For remote on/off switching of ancillary components in a system, such as power
amplifiers or active speakers, the C 320BEE 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 320BEE 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 improve-
ments to the overall sound. The C 320BEE tone controls only work at the frequency
extremes leaving the critical mid-band essentially unaltered. The tone control cir-
cuits can be completely bypassed by using the tone defeat switch.
The C 320BEE also incorporates NAD's acclaimed switchable "Soft ClippingTM" circuit,
which significantly reduces the risk of damage to loudspeakers due to prolonged
high power operation.
Design
PowerDriveTM:
NAD takes a stance to the overblown power ratings quoted by many competitors,
which don't give a realistic indication of an amplifier's true capabilities. NAD's Full
Disclosure Power ratings give the guaranteed minimum continuous power output
under the "worst case" loading of 4 Ohms and 20Hz to 20kHz with all channels driv-
en simultaneously, as well as the more meaningful in actual use dynamic power rat-
ings.
The C 320BEE benefits from NAD's proprietary PowerDriveTM topology, this further
refinement of Power Envelope and ISC, is now well established and used throughout
much of the NAD product range. PowerDriveTM endows the C 320BEE with tremen-
dous dynamic power and low impedance drive capability, seemingly contradictory
traits to be found in a single amplifier. This is accomplished by using a multistage
power supply with a very sophisticated analog amplifier determining whether to
switch in a high voltage or a high current rail depending on the specific operating
condition. This optimization is fully automatic and utterly transparent in operation;
the result is that the C 320BEE sounds far larger and more powerful than its contin-
uous power rating would suggest.
PowerDriveTM is a practical approach to enable an amplifier to easily deal with musi-
cal dynamics and difficult speaker loads. Most impressive are the C 320BEE's
dynamic capabilities; up to 210W into 2 ohms and up to 50 amps peak current
capability!
Performance
Compared to the original C 320, the BEE version features many circuit refinements
trickled down from the award winning C 370 (European Amplifier of the Year 2001-
2002) including active current sources and common base current followers in the
power amp section. The effect of this is to improve supply rejection to unprecedent-
ed levels, well beyond the audible frequency range. This dramatically reduces
dynamic intermodulation distortion between music signal components in different
frequency ranges, and between the music signals and the power supply ripple and
distortion components. In measurement terms, static and dynamic IM distortion
are reduced by between 10dB to 20dB. (to between -90dB and - 100dB.) In audible
terms this improves definition, purity and resolution, hence imaging.
We have also improved the accuracy of the tone controls, increasing their boost/cut
range by 1.5dB and have specified a better quality volume control. While some of
these are small improvements in and of themselves, there is an additive effect that
results in a more refined and authoritative sound, building on the strengths of the
already very good design of the original C 320. The sensible Tone Control character-
istics, sonically transparent relay input switching, and Pure Class A modular preamp
stages and power amp driver stages, are carried over from the previous model. So
are the patented power amp output stages, unique low resistance binding post
design, copper bus bars for high-current paths, and low-noise discrete regulators.
The chosen topology and use of low noise FET class A preamp stages ensures very
high S/N ratio, even at low volume settings. In fact, the noise level produced by
even the most efficient speakers is well below 0 dBA SPL, by definition inaudible.
This is 10-15 dB better than the industry average - even for very high end compo-
nent hi-fi!
