C 165BEE Stereo Preamplifier
> POSITIONING
The C 165BEE is the perfect complement to NAD’s C 275BEE Power Amplifier making a reference level of performance available for far less money
than previously possible. Attention to the most minute detail is evident everywhere, from the heavy gauge steel chassis to the sophisticated
power supplies and custom Class A gain modules taken straight from the NAD Masters Series components.

The C 165BEE is an all new design representing a lifetime
of design experience from NAD’s renowned Director of
Advanced Developments, Bjorn Erik Edvardsen. New
semiconductors and improved production techniques
such as surface mount devices (SMDs) have created
opportunities for performance far beyond expectation
when compared to previous products in this price range.
Compared to its predecessor the C 162, an improved
tone control circuit and revised PCB layout has reduced
distortion and noise to unprecedented levels when
combined with the high signal capacity of the NAD Class
A Gain Modules.
Class A gain modules combine the short signal path
advantage of IC based OPAmps with the higher signal
and current capacity of discrete transistors. Here SMD
is used to miniaturize the circuit while the extruded
aluminum heat sink keeps all parts at the optimal
operating temperature for ultra low distortion. This
unique NAD development endows the C 165BEE with
lightening fast transient response and bass extension
and definition that is uncommon at this price level. High
frequencies are extended, silky smooth and grain-free.
In the phono stage we have added 3 position switches to
individually select the resistance and capacitance of the

phono stage to allow precise matching of most

cartridges. Other refinements have lowered noise
and improved the overload margin. Precision close
tolerance parts are used to achieve nearly perfect
RIAA response.
controls. Affecting only the frequency extremes
they leave the critical midrange untouched. Their
moderate action is perfect for touching up the tonal
balance of all the less than perfect recordings in your
collection. A Tone Defeat switch quickly selects flat
response and bypasses all the tone control circuitry.
We’ve also improved the headphone amplifying
circuit to better drive studio quality high impedance
headphones. Taken together, these improvements
mark a sharp upturn in performance that simply
must be heard, to be fully appreciated!
A full function remote control also includes controls
for other NAD components allowing a ‘one remote’
solution for your NAD system.
Features
With a 12V trigger output and IR inputs and outputs
on the rear panel, the C165BEE is ready to integrate
with CI control systems. Discrete On/Off codes and
direct access to inputs make programming easy.
Unlike many high-end preamps that skimp on inputs
and features, the C 165BEE has all the flexibility
you will ever need. Starting with 6 line level inputs
and the previously mentioned MC/MM phono input,
the C 165BEE also includes a superbly designed
tone control circuit. While tone control circuits in
general tend to hurt performance by adding noise
and distortion, the C 165BEE is a textbook example
of how to correctly implement high fidelity tone

Green Features
NAD has responded quickly and responsibly to the
new awareness of environmental damage caused
by human activity. The C 165BEE is manufactured
without the heavy metals that have been identified
as harmful to the environment and manufacturing
processes meet the latest stringent international
standards. Standby power consumption is best in
its class at <1 watt.
Value
We don’t think you’ll find another preamp with
the same pedigree, performance, and flexibility
at anywhere near the low price of the C 165BEE.
Classic understated styling, superb build quality and
true engineering sophistication at an affordable
price; that’s the NAD difference.
