Purifi Eigentakt Amplification
The C 298 uses advanced Eigentakt™ technology to minimise distortion and noise across the audible range.
This results in greater detail, improved dynamics and a more natural, open sound presentation.
Power with Control and Headroom
The C 298 delivers strong continuous power with excellent dynamic headroom for demanding music.
It maintains composure across quiet and high-output passages, ensuring clarity and control at all levels.
Flexible Stereo or Mono Operation
The C 298 can operate in stereo mode or be bridged into a powerful mono amplifier delivering up to 620W.
This flexibility allows easy system upgrades and expansion over time.
Designed for Real-World Systems
Features like auto turn-on, 12V triggers and daisy-chain outputs simplify integration into complex systems.
These ensure reliable operation and consistent performance in both visible and hidden installations.
