3.Connect the Krell CAST cables from your CAST-enabled preamplifier or source component to the left and right Krell CAST 4-pin bayonet inputs (16) on the amplifier (1) back panel. For balanced operation, connect the intercon- nect cable from your preamplifier to the balanced XLR input (15) on the ampli- fier back panel.

4.Connect the loudspeaker cables to the amplifier binding posts (17), located on the amplifier back panel. Amplifier binding posts accept spade lugs only.

5.Insert the AC mains power cord plug into the IEC power cord receptacle (20), on the back panel of the power supply chassis.

6.Turn to Amplifier Operation, on page 22.

Note

If a CAST and balanced source are connected to the amplifier during the initial installa- tion, the Evolution One amplifier defaults to CAST, when it is powered on. If only one source is connected, the amplifier will automatically select that source. For more informa- tion, see Switching Between CAST and Balanced Inputs, on page 23.

DC Protection Circuitry / Using a Tube Preamplifier

The Evolution amplifier has a built-in DC monitor that continuously monitors the audio signal at the input. If too high a level of DC is detected, the amplifier auto- matically mutes the output and engages DC coupling capacitors at the input stage.

For more information about DC protection circuitry features, see Amplifier Troubleshooting, on page 26.

Evolution One specifications

Krell Industries is synonymous with high-fidelity audio and innovative engineering, showcasing their prowess in speaker design with the Evolution One. This speaker embodies the cutting-edge technology and striking aesthetics that Krell is recognized for in the audiophile community.

The Evolution One features a unique dual-woofer configuration, delivering powerful bass response without distortion. Each woofer is meticulously crafted from advanced composite materials, ensuring that the sound remains accurate and dynamic, even at high volumes. This design aligns perfectly with Krell's dedication to reproducing music with the utmost authenticity.

At the heart of the Evolution One is Krell's proprietary CAST (Current Mode Amplification) technology. This innovation sets Krell apart from competitors by allowing the signal to flow through a path that maintains the purity of the audio signal. By operating in current mode rather than voltage mode, CAST drastically reduces the impact of circuit interference that often plagues traditional audio systems. The result is a level of transparency and low distortion that appeals to even the most discerning audiophiles.

The speaker also incorporates advanced crossover technology, which seamlessly integrates the woofers and tweeter. Krell employs a fourth-order Linkwitz-Riley crossover to ensure that the different drivers work in perfect harmony. This feature aids in achieving a balanced and cohesive soundstage, enhancing the listening experience across various musical genres.

Visually, the Evolution One is a statement piece. Its sleek, modern design is complemented by a high-gloss finish, ensuring it not only sounds exceptional but also serves as an elegant addition to any audio setup. The robust cabinet construction eliminates unwanted vibrations, further enhancing sound clarity.

Moreover, the Evolution One is equipped with advanced bi-wiring and bi-amping options, allowing audiophiles to optimize their setups based on personal preferences and system requirements. This flexibility makes the Evolution One an adaptable choice for those looking to refine their audio systems further.

In summary, the Krell Industries Evolution One is a culmination of innovative technology, premium materials, and exquisite design. With features such as dual-woofer configurations, CAST technology, and advanced crossover design, it stands as a testament to Krell's commitment to delivering high-fidelity audio experiences that resonate with both casual listeners and dedicated audiophiles alike.
