NAD C272 - Manual

• PowerDrive™
• High Current Holmgren™ Toroidal Power Transformer
• Bridgeable to 300W mono (8 ohms)
• Both fi xed and variable inputs, switch selectable
• Double set of loudspeaker binding posts to facilitate
bi-wiring
• All Discrete Circuitry
• Gold plated RCA Connectors
• NAD Soft Clipping™
• 12V Trigger Input for remote Stand-by/On switching
• IEC Detachable Power Cable
• ATO Logic
The output relay protection circuit provides silent switch
on and off, together with non-evasive protection against
error conditions such as short circuits and overheating.
Using the 12V trigger input, the C 272 is easily switched
On or to Stand-by from remote components featuring
12V trigger outputs. NAD’s own C 162 preamp sport 12V
trigger outputs, for instance. The inclusion of 12V triggers
make the C 272 an ideal choice for demanding, high
quality Custom Install applications. Equipped with two
sets of loudspeaker binding posts, adding a second pair of
speakers becomes easy. The second set of binding posts
will also facilitate “bi-wiring” speakers, a practice popular
with demanding audiophiles.
PowerDrive™
The C 272 also benefi ts from NAD’s proprietary
PowerDrive amplifi cation circuitry, now well established
and used in many NAD models including the highly
reviewed C 320BEE and C 350. PowerDrive allows the
C 272 to deliver maximum performance under virtually
any circumstance, independent of the loudspeakers it is
driving. The circuitry automatically senses the impedance
of the loudspeaker and then adjusts its power supply
settings to best cope with that specifi c load.
With PowerDrive, the relationship of voltage to current
is kept at an ideal proportion, eliminating the current
limiting distortion common in lesser designs. This also
gives it an unusual characteristic compared to traditional
amplifi ers when measuring its continuous output power;
the RMS output power remains the same at 150 watts with
either an eight or a four-ohm load. This is not unusual for
NAD however. NAD takes a stance against the mindless
“brochure power” approach which doesn’t give a realistic
indication of an amplifi er’s true capabilities. Instead,
PowerDrive is a practical approach to enable an amplifi er
to easily deal with musical dynamics and diffi cult speaker
loads. More meaningful in the real world are the C 272’s
dynamic capabilities; up to 450 watts into 2 ohms and up to
70 amps current capability into 1 ohm!
C 272 Stereo Power Amplifi er
The all-new NAD C 272 is part of a new range
of amplifi ers, which will further enhance
NAD’s enviable reputation for state of the art
products at sensible prices. The key design
goals of the new range are PERFORMANCE
and RELIABILITY. Both are attained at a very
competitive price through effi cient innovative
design, simple circuitry and meticulous
engineering.
“Building Block Concept”
For maximum fl exibility, the C 272 can operate
in bridged mono mode, nearly tripling its single
channel stereo mode continuous power rating
into 8 ohms.This makes it an ideal choice for a
subwoofer amplifi er or part of a high powered
home theatre or stereo system.
Additional Features
The C 272 also incorporates NAD’s acclaimed
switchable “Soft Clipping” circuit that
signifi cantly reduces the risk of damage to
loudspeakers due to prolonged high power
operation. The technological effort behind the
C 272 results in a relaxed unstrained musicality,
