equipped with a 12V trigger system. When switching the
pre-ampli er on, the 12V trigger output is also activated
which in turn can
activate a 12V trigger input and switch on the
remote devices.
Unique is the Variable Pre-out 2 facility. Many systems can
bene t from the use of multiple power ampli ers for “Bi-
Amping” (using separate power ampli ers to drive the bass
and treble section of a loudspeaker). Many speakers are all
ready set up for this with separate inputs for the low and
high frequency sections. But not all power ampli ers are
identical in gain (ampli cation factor). With the Variable
Pre-out 2 facility differences in loudness between power
ampli ers up to 12dB can be dialed out precisely.
The low output impedance on the Pre-outputs allow the
C 162 to drive several power ampli ers in parallel and/
or the use of long interconnect cables (without the
degradation of the performance that can so often
become apparent when long cables are used).
Design:
Following NAD’s “Music First” design brief, the C 162
utilizes completely new, innovative circuit topology which
allows for investment in high speci cation and close
tolerance components. Metal  lm resistors, polypropylene
capacitors, hermetically sealed relays and the Alps “Blue
Velvet” motorized volume control are a few examples of
this.
Special attention has been paid to the power supply
section of the C 162. The toroidal transformer has 4
separate secondary windings followed by 6 main low-
noise regulators. From here no less than 6 super low-
noise subsidiary regulators and active  lters are used to
maximize supply rejection for all sections of the C 162 to
more than 100dB.
Often other manufacturers disregard the importance of a
phono stage. NAD recognizes the performance potential
of a good turntable and has made sure that the C 162 will
not be the limiting factor. The MC phono stage is built
pretty much like a small “power amp” so that a wide range
of MC cartridges can be used while keeping noise very
low combined with a high overload margin. Likewise, the
C 162 Stereo Preampli er
With the arrival of the all new NAD Model
C 162 pre-ampli er you can get the best of
both worlds: Ultimate performance combined
with the convenience of remote control. Its
outward simplicity belies the sophistication of
the circuitry inside.
Features:
With 6 line inputs (two of which are Tape In/
Out) and an MM/MC phono input available it’s
unlikely you will run out of inputs to connect
your sources to. The C 162 is fully remote
controlled and comes supplied with the NAD
C Series system remote control. As the
C 162 has NAD Link, the remote control will
also operate many other NAD products such
as CD players, tuner etc. The headphone
socket will drive virtually any non-electrostatic
headphones.
It is fashionable to omit tone controls
nowadays: However, provided that the tone
controls are properly designed, they can really
be a useful tool to make improvements to the
overall sound. The C 162 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.
For remote on/off switching of ancillary
components in a system, such as power
ampli ers or active speakers, the C 162 is

MM phono stage also can cope with a wide range of cartridges and
operates entirely in Class A. The built-in infrasonic  lter  lters out
unwanted rumble components from the turntable or record itself
but without introducing any signi cant group delays. To ensure
accurate RIAA response the entire circuit uses 1% tolerance metal
 lm resistors and 2% tolerance capacitors.
Essentially the same circuitry used for the phono circuit is also
used for both the line input and output stage: A modular FET amp
operating in Class A. The line output stage is capable of driving 10V
into 600 ohms. This, combined with the high input impedance of
the line input ampli er (500k ohms) means that the C 162 can be
combined with a vast range of sources and power ampli ers. For
the inputs themselves, the NAD engineers have opted for using
relays rather then using electronic switching between sources.
All input and output sockets are gold plated.
Often it is said that performance and convenience don’t go
together, but the NAD Model C 162 is the exception to the rule. At
this reasonable price, the Model C 162 deserves to partner with the
 nest of ancillary components.
