Unique is the Variable Pre-out 2 facility. Many systems can
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). Many speakers are all
ready set up for this with separate inputs for the low and
high frequency sections. But not all power amplifiers are
identical in gain (amplification factor). With the Variable
Pre-out 2 facility differences in loudness between power
amplifiers up to 12dB can be dialed out precisely.

C 162 pre-amplifier you can get the best of
both worlds: Ultimate performance combined
outward simplicity belies the sophistication of
the circuitry inside.
The low output impedance on the Pre-outputs allow the
C 162 to drive several power amplifiers 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).
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.
Design:
Following NAD’s “Music First” design brief, the C 162
utilizes completely new, innovative circuit topology which
allows for investment in high specification and close
tolerance components. Metal film resistors, polypropylene
capacitors, hermetically sealed relays and the Alps “Blue
Velvet” motorized volume control are a few examples of
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 filters are used to
maximize supply rejection for all sections of the C 162 to
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.
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
For remote on/off switching of ancillary
components in a system, such as power
amplifiers or active speakers, the C 162 is
