NAD C 298 Stereo Power Amplifier

The C 298 is a simple, powerful power amplifier designed to offer flexibility and amazing sound. This innovative product uses Purifi Eigentakt™ to reduce unwanted noise and deliver impeccable sound from any input device. The inputs come equipped with a trim control, so you can easily mix and match other components to suit your liking. Plus, it also has a ground lug which is great at reducing noise in multi-unit systems that contain more complex parts and features. This stereo amplifier is ideal for true audiophiles looking to streamline their sound system without sacrificing quality.

Sophisticated Power

NAD has moved away from the old fashioned and very power hungry linear power supplies and Class AB output stages that waste nearly half of the energy consumed producing heat rather than sound. Instead we have 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 created some of the best performing amplifiers regardless of basic design principle. These new designs are very linear over a wide bandwidth and provide consistent performance into all speaker loads, providing a dramatic advance over previous models.

The generously dimensioned power supply easily allows for 185 watts continuous and over 570 watts instantaneous power for short term musical transients. Innovative Asymmetrical Power-Drive fully utilizes every last watt available with its vast reserves of dynamic power available to accurately reproduce musical transients without distortion or compression.

It can operate with any AC mains voltage from 100v to 240v and provides pure DC power to all the various stages of the C 298. 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.
