High-Current Krell Amplification

The KAV-2250 was engineered to deliver substantial output power while maintaining the speed, control, and wide frequency response associated with Krell amplification.

Rated at 250 watts per channel into 8 ohms, the amplifier doubles its rated stereo output to 500 watts per channel into 4 ohms. This power capability makes it suitable for a wide range of demanding floorstanding loudspeakers and high-performance stereo systems.

Krell Current Mode circuitry operates its audio gain stages in the current domain rather than the conventional voltage domain, providing the foundation for fast transient response and extended bandwidth.

Balanced Connectivity and Flexible System Integration

The Krell KAV-2250 features balanced XLR and single-ended RCA inputs for connection to stereo preamplifiers, surround processors, and other compatible line-level sources.

Its two amplifier channels can also be configured for bridged-mono operation, delivering a rated 1,000 watts into an 8-ohm load. The amplifier additionally supports Krell Multi Amp Throughput (MAT), allowing flexible signal distribution for compatible multi-amplifier configurations.

12V trigger input and output connections simplify integration into home audio and theater systems.
