Should you wish to change between stereo and monaural operation please refer to section D. 5. This is only necessary when changing either unit from stereo to monooperation.

All KPAare shipped from the factory set-up for stereo operation. Please refer to section E. 1. d for information regarding dual-monooperation.

B. GENERAL INFORMATION

The KRELLKBL(Krell Balanced Line) and KPA(Krell Phono Amplifier)

present many new concepts in preamplifier design. The traditional preamplifier contains both a phono section and a line section. The KBLand KPAdivide these functions into two separate units. This was done for several reasons. The primary motivation was to allow adequate space to accommodatethe latest evolutions of preamplifier circuitry and functions.

KBL, KPA specifications

Krell Industries, a name synonymous with high-fidelity audio, has made significant strides in the high-end audio equipment market with its KPA and KBL models. These amplifiers epitomize Krell's commitment to exceptional sound quality, advanced technologies, and innovative design, catering to audiophiles who seek unparalleled listening experiences.

The Krell KPA, a cutting-edge power amplifier, showcases Krell’s renowned high-performance design. One of its standout features is the use of an ultra-linear, class-A amplification topology. This design principle not only enhances audio fidelity but also ensures lower distortion levels, allowing music to be reproduced with incredible detail and clarity. The KPA is also engineered to deliver substantial power output, with sufficient reserves to drive even the most demanding speaker loads, making it an ideal choice for dynamic music genres.

Another noteworthy aspect of the KPA is its sophisticated thermal management system. The use of oversized heatsinks and intelligent fan control keeps the amplifier cool during extended listening sessions, thereby preserving performance and longevity. The KPA also includes advanced connectivity options, including RCA and XLR inputs, which cater to a variety of system configurations, ensuring versatility in integration with other high-end audio components.

Conversely, the Krell KBL, a preamplifier model, is designed to complement the power capabilities of the KPA. The KBL's main features include a fully balanced design and multiple gain stages that contribute to its exceptional signal-to-noise ratio. This ensures that the audio signal remains pristine, free from interference and distortion, resulting in a true-to-life reproduction of recordings. The preamplifier also offers an impressive array of inputs, including analog and digital options, allowing users flexibility in their source selection.

Both the KPA and KBL incorporate Krell's proprietary technologies, such as the Cast™ technology, which facilitates a three-dimensional soundstage and unrivaled musical character. This technology seamlessly enhances the relationship between components, creating a cohesive sound that many audiophiles strive for. Furthermore, the build quality of both models is exceptional, with premium materials and craftsmanship that reflect Krell's dedication to performance and aesthetics.

In summary, Krell Industries' KPA and KBL models combine innovative technologies, remarkable power, and unmatched audio quality, making them ideal choices for serious music lovers. Their features, performance, and elegant design showcase Krell's unwavering commitment to the pursuit of audio excellence, setting new standards in the high-end audio luxury market.
