With the arrival of the all new NAD Model C 162 pre-amplifi 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 amplifi ers or active speakers, the C 162 is
activate a 12V trigger input and switch on the remote devices.
Unique is the Variable Pre-out 2 facility. Many systems can benefi t from the use of multiple power amplifi ers for “BiAmping” (using separate power amplifi 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 amplifi ers are identical in gain (amplifi cation factor). With the Variable Pre-out 2 facility differences in loudness between power amplifi 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 amplifi 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 specifi cation and close tolerance components. Metal fi 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 lownoise regulators. From here no less than 6 super lownoise subsidiary regulators and active fi 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
