The C 298 may be a basic power amplifier, but we've carefully thought through all the typical use cases to create rich feature content. Selectable balanced inputs make the C 298 a natural for use in the studio or for connection to high-end preamps and processors.
These inputs include a trim control useful for adapting to other components. A line output allows for greater power addition on the same channel for additional speakers or subwoofers.
Automatic detection with selectable threshold is perfect for automating complex systems or hiding the amplifier in a closet. We even include a ground plug which can be very helpful in eliminating ground loops and noise in complex multi-unit systems.
Added to all this connectivity is a bridge switch that turns the C 298 into an incredibly powerful monoblock amplifier. Start with one and add a second C 298 later when you upgrade your speakers.
It's surprising how many seemingly advanced products are on the market today, often overlooking many of the most basic requirements for performance. Low noise circuitry, precise channel balance, proper input and output impedance characteristics, high overload margins and stability under difficult speaker loads.
NAD starts by getting these things precisely and moves forward from there. Our line inputs, both balanced and single-ended, can accommodate all types of analog source components by offering ideal input impedance characteristics with ultra-low noise linear buffer amplifiers to prevent any sonic degradation caused by improper loading of the source device. .
These are all the details that can be heard.
NAD has moved away from outdated and very power-hungry linear power supplies and class AB output stages that waste almost half of the power consumed producing heat instead of sound. Instead we have developed better performing circuits based on switching power supplies and Class D output stages.
NAD's advanced work in this area has created some of the best performing amplifiers, regardless of the basic design principle. These new designs are highly linear over a wide bandwidth and provide consistent performance across all speaker loads, providing a dramatic improvement over previous models.
The generously sized power supply easily enables 185 watts continuous and over 570 watts instantaneous for short duration musical transients. The innovative Asymmetrical Power-Drive fully utilizes every last available watt with its vast reserves of available dynamic power to accurately reproduce musical transients without distortion or compression.
It can operate on any AC mains voltage from 100 to 240 V and provides pure DC power to all stages of the C 298. This highly efficient supply also provides near perfect voltage regulation over a wide range of conditions and provides a solid and noise-free base for the amplification stages.
Purifi is a Danish technology company that has brought together several of the industry's leading engineers to apply advanced mathematical modeling to solve the latest limitations of audio amplifiers.
Although there are many good-sounding amplifiers on the market today, Purifi has taken a fresh look at all aspects of amplifier performance and found many seemingly small nonlinearities that can make a dramatic difference in the overall sound.
This return to basic principles has resulted in a surprisingly simple approach to some remarkably complex problems. With features and technology unmatched in other amplifiers in its class, the C 298 amplifier is an easy upgrade for any system and an amazing partner for the most sophisticated and advanced speakers on the market.
