NAD C 268 Stereo Power Amplifier

A remarkably affordable stereo amplifier, the NAD C 268 has
features and technology unmatched by other amplifiers in its class. Designed
for multiple stereo setups, the C 268 can be used in a variety of scenarios,
including traditional stacks with a preamplifier or for bi-amping your
favourite loudspeakers. The NAD C 268 is even bridgeable, seamlessly
transforming its bountiful output from 80 x 2 to an outstanding 300 watts.
Although the C 268 may appear to be a straightforward power amplifier, this
Classic Series amp is brimming with rich features that will elevate your
system.

NAD C 268 Stereo Power Amplifier

Amazing Flexibility

As with every amp in the Classic Series, we here at NAD have
carefully thought through all the possible use cases and strategically chosen
the most essential of features. Thanks to selectable balanced inputs, the C 268
is a natural mate for high-end preamps and processors. These inputs include a trim
control useful for matching with other components, or for use in bi-amping
speakers. A line out allows further addition of power on the same channel for
extra speakers or subwoofers. On top of all this connectivity is a bridge
switch that turns the C 268 into an amazingly powerful Monobloc amplifier.

You can also pair the C 268 with the NAD C 368 Hybrid
Digital DAC Amplifier, and with both units bridged for mono, 300 watts per
channel of distortion-free sound become available for your listening pleasure.
The C 268’s auto-sense feature with selectable threshold is perfect for
automating complex systems or for hiding the amp out of sight in a cabinet.
Included with the C 268 is a ground lug that is very useful for eliminating
ground loops and noise in complex multi-unit systems.

Getting the Basics Right

As a member of NAD’s Classic Series, the C 268 delivers a
richly satisfying sonic performance thanks to its “music-first” features.
Accurate channel balance, proper input and output impedance characteristics,
and low noise circuits all come together within this one stereo power
amplifier. Additionally, the C 268’s line inputs, both balanced and
single-ended, can accommodate all kinds of analogue source components by
offering ideal input impedance traits with linear ultra-low-noise buffer
amplifiers to prevent any sonic degradation caused by unfitting loading of the
source device.

Sophisticated Power

Having moved away from old fashioned linear power supplies
and Class AB output stages, NAD has developed even better performing circuits
based on switch mode power supplies and Class D output stages. Once thought to
be inferior to traditional topologies, NAD’s advanced work in this area has
resulted in some of the best performing amplifiers regardless of basic design
principle. The overall design of the C 268 is very linear over a wide
bandwidth, providing dramatic advances over previous models with consistent
performance into all speaker loads.

The power supply of the C 268 is capable of nearly 200 watts
continuously and over 500 watts instantaneously, allowing for short term
musical transients. NAD’s innovative asymmetrical PowerDrive fully utilizes
every last watt available with its vast reserves of dynamic power available to
accurately reproduce the most demanding music without distortion or
compression. It can also operate with any AC mains voltage from 100V to 240V,
and provides pure DC power to all the various stages of the C 268. This highly
efficient supply also provides near perfect regulation of voltage across a wide
range of conditions and provides a solid noise-free foundation for the
amplifying stages.

The C 268 uses a customised version of the proven Hypex UcD
output stage. This allows for massive power with nearly immeasurable distortion
and noise in the audible range. Every detail of this design has been carefully
crafted and perfectly executed to wring out ever last drop of performance.
