Features & Specs
Purifi Eigentakt™ amplification for ultra-low noise and distortion
Designed to minimize distortion and noise across the audible range so fine detail, spatial cues, and dynamics come through naturally without harshness or haze.
185W x 2 into 8 ohms; 340W x 2 into 4 ohms
High continuous output power helps the amplifier stay composed at real listening levels, keeping bass tight and transients clean even when speakers become demanding.
Bridgeable mono mode up to 620W into 8 ohms
Run the C 298 as a potent monoblock for maximum output, or build a future upgrade path by adding a second unit for a dual-mono system.
Balanced XLR and RCA inputs with input level control
Connect easily to a wide variety of preamps and sources, and fine-tune input sensitivity to match system gain structure for optimal performance.
Line output for daisy chaining
Expand your system without complication—feed another amplifier for additional channels, zones, or future upgrades while keeping wiring clean.
Auto turn-on and 12V trigger integration
A selectable signal-sensing threshold plus trigger in/out streamlines daily use, especially in rack systems or hidden installs where manual power control is inconvenient.
