NAD C 298 Power Amplifier

A 185 W class-D amp that can be bridged to 620 W, with control inputs and outputs
The C 298 uses NAD's Eigentakt™ (self-clocking) technology, first introduced in the EISA Award-winning Masters M33. This affordable power amp is designed to be the perfect companion for the C 658 BluOS Streaming DAC pre-amp.
The C 298 may be a power amp, but NAD has carefully thought through all the use cases in modern audio environments and created a rich feature content. Selectable balanced inputs make the C 298 a natural for studio use or connection to high-end preamps and processors. These inputs have trim controls, allowing for precise matching to other components. A line out allows the addition of subwoofers or a second zone.
An auto-sense feature with selectable threshold is perfect for automating complex systems or hiding the amp out of sight in a cabinet. There is also a ground lug, which can eliminate ground loops and noise in complex multi-unit systems. Finally, when you're ready to upgrade, the C 298 can be bridged to deliver a massive 620 W in mono. Add another C 298 to drive high-end speakers.
