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
